Hey guys, I am like a very top developer toptal certified and earning well . Every app I can think of has very much competition. But I, being a redditor myself , wanted to see what ideas you can think of?

I will decide what to build based on Upvotes I get! When the app gets live , I will get a working MVP within week whatever you say ! For reddit users I will give everyone a free trial !

Hoping my fellow redditors help me bring it to life!!!

Comment your idea , what makes it unique and what is competition level (if you know) .

Thoughts? Made a live demo which you can play around here: https://the-eureka-database-eg44.lovable.app

Básicamente tengo mucha familia y amigos y es un dolor recordar los gustos y los cumpleaños de todo el mundo...

Una app tipo asistente que recuerde cumpleaños, que te dé ideas de regalos para cada persona e incluso un enlace al regalo o algo sin tener que decirle cada vez los intereses...

Que lo único que haya que rellenar sea la fecha de nacimiento y los gustos de esa persona... Las que hay son muy genéricas y tienes que rellenar datos cada vez...

Ya he probado Finder y Giftster y cada una tiene sus cosas, pero no quiero andar con varias aplicaciones para lo mismo...

I find myself texting my todo list to a random number to keep track of my stuff just because I really like having it in the messages app. Has anyone made some sort of bot that I could text like a human to keep track of my todo list?

Does anyone else have a similar problem/desire?

About a year ago, I became obsessed with a simple idea: instead of waiting for people to fill out forms or book demos, could software identify real intent from public conversations and filter out the noise?

I spent the past year building an intent engine that ingests public discussions, classifies them, and runs them through a filtration pipeline to surface only the strongest signals.

The interesting part is that I realized the engine itself isn't the product it's infrastructure. The question is: what product should sit on top of it?

I recently put together a basic version, but it hasn't gained any meaningful traction yet. Rather than adding more features blindly, I'd rather understand what people would genuinely find valuable enough to pay for.

If you had access to an engine that could continuously analyze public conversations and detect meaningful intent, what problem would you want it to solve?

Some possibilities I've considered:

• Finding potential customers before they start evaluating vendors.
• Continuous market or competitor research.
• Discovering recurring feature requests or product pain points.
• Detecting companies likely to switch away from a competitor.
• Something I haven't thought of.

I'm not looking to promote anything or collect signups I deliberately haven't linked the project because I'd rather hear unbiased opinions.

If you think this idea is fundamentally flawed, I'd honestly like to hear why. And if you think there's a niche where this would be genuinely useful, I'd love to understand the workflow, who the customer is, and why they'd pay for it.

Thanks in advance I'm hoping to avoid spending the next six months building something nobody actually wants.

I've worked in social listening and health marketing analytics for the past 5 years now and always wondered what made people comfortable enough to share their personal health information online. With the implementation of agentic AI in almost every telehealth platform, I know that people are willing to "talk" to synthetic health care providers like they would to their PCP.

That being said, I have an app idea that combines agentic AI and social listening (real posts from real people) but in a private environment, a way for those who don't want to post on Reddit or TikTok to ask questions about their health problems, physical and mental, and insurance woes.

Essentially, a patient could describe a persona of a person they want to have a conversation with (doctor, friend, caretaker) and real time social data (API integration) matches the patient with the advice they need to seek personalized care WITHOUT posting online or asking someone in real life first.

I can see this being used for those who are anxious or stressed about their health and don't exactly want to speak to a friend or health professional right away, and don't want to turn to the internet to post about their symptoms.

Is this idea feasible or a waste of time and effort?

I’m exploring whether there is a real need for a camera-first troubleshooting assistant, and I’d appreciate honest criticism before investing more time in it. The concept is simple: someone points their phone at an appliance, tool, router or electronic device, explains the problem, and receives one troubleshooting step at a time instead of searching through forums and long videos. I imagine the initial users would be renters, homeowners and DIY beginners who want a sensible first diagnostic step before calling a technician. The technical approach includes a specialized on-device language model trained with synthetic troubleshooting data. The intention is to let people use a local mode without sending details about their home or equipment to a cloud model. Cloud assistance could remain optional for harder problems. My concern is that this may still be an unnecessary product when people already have Google, YouTube, manuals, repair forums and general AI assistants. On-device processing may improve privacy, but that alone may not be enough to justify a dedicated app. It would also need firm safety boundaries. It should never encourage users to attempt electrical, gas or other hazardous work that requires a qualified professional. I’m not sharing a product link or asking anyone to download anything. I’m trying to validate the underlying problem. I’d especially value feedback on: Is this problem painful enough to justify a dedicated app? In what situation would you actually use it instead of Google or YouTube? Which type of user has the strongest need for it? Would local, on-device processing materially affect your trust? What safety or liability issue could make the idea unworkable?

Please be brutal: is this a useful product, or just an AI wrapper around Google, YouTube, and repair forums?

What if you could rent almost anything from people nearby instead of buying it? 🤔

I’m building a peer-to-peer rental marketplace where people can rent out their unused items, vehicles, and spaces—and earn money from assets that would otherwise sit idle.

Imagine renting:
🔧 Tools & garden equipment
🏕️ Camping gear
🎉 Party equipment
🚐 Trailers & vehicles
📦 Storage spaces
🚗 Driveways & parking spaces
🏡 Workshops, studios & more

Instead of spending hundreds (or thousands) on something you’ll only use once, simply rent it from someone in your local community. And if you own something that’s rarely used, why not turn it into an extra source of income?

Think of it as Airbnb, but for everyday items and spaces.

I’m still building the idea and would love your feedback.

Would you use an app like this? What would you rent out—or rent yourself? Let me know in the comments! 👇

Hi everyone!

I'm currently building a note-taking app and would love to get some ideas from people who actually use these kinds of apps.

If you could add one feature or tool that would make a note-taking app significantly more useful for studying, work, or everyday organization, what would it be? It can be something you've always wished existed or something current apps don't do well.

I'd really appreciate any ideas. Thanks!

Open Source and free, no sell and no enroll, hope you'll have fun !

This is an unapologetically claude code vibe-coded project; the approach is explained here: https://lia.jeyswork.com/story

If you like it, please don't hesitate to show your support with a star on GitHub!

LIA acts as a true personal assistant. It is proactive, featuring its own distinct personality and a complex emotional system, an evolving structured memory, its own reflective memory of your conversations, and all the standard tools (image creation/editing, RAG, skills, MCP, scheduled tasks, etc.)—all wrapped in a seamless "one-click" interface (details here: https://lia.jeyswork.com/why).

I paid special attention to code quality and documentation, treating it exactly like a professional enterprise-grade project. This ensures that anyone can easily take ownership of the source code and build upon a clean, robust, and highly scalable foundation (details here: https://lia.jeyswork.com/how).

On another note, once self-hosted, it can double as a family AI server. As an administrator, you have full control to manage and monitor the API consumption of your family members, friends, etc.

I was thinking about how convenient it would be if you could drop a small object into any drink and instantly create a sparkling texture without changing the flavor.

It wouldn’t need to be an ice cube — maybe a portable, shelf-stable object.

Do you think something like this is technically possible or would you use it?

I’m looking to build a SaaS and want ideas from people around the world — what’s a problem in your daily life, job, or hobby that you wish there was a simple tool/app for? Doesn’t matter the industry, even something small or oddly specific is welcome.

There’s this niche I really like to watch on YouTube like travel content but I usually like to watch the ones like Billy Martin or discover connection where they talk to people and travel the world for cheap or for what they have. Imagine a game where you can go anywhere in the world and meet ai npcs , befriend them , invite them places , rent mopeds , cars , go travel the world with like a starting amount of money and being able to live on the generosity of the people in the game (npcs) and see the world seems sick but expensive I also have no idea how to code 😭💔

so i'm 20, been building this app solo for the past few months and i genuinely can't tell anymore if it's good or if i'm too deep in it. need outside eyes.

it's called RizeAI. the basic idea: every wearable and health app just gives you numbers. sleep score 42, recovery red, HRV down. cool. and then what? you still feel like garbage at 2pm and nobody tells you what to actually do about it.

so my app takes your real data from apple health, sleep, resting heart rate, workouts, whatever your wearable writes, and instead of another score it builds you an actual plan for the day. when to have your first coffee and when to hold off. what supplements make sense for you today and when to take them. focus windows for when your energy actually peaks. when your crash is coming and what to do before it hits. it even checks the weather, so on a hot day it bumps your hydration and tells you to train earlier.

every recommendation has a little "why" under it based on your numbers, like "resting heart rate 54 + 7h light sleep, so magnesium before your peak window." no two people get the same plan because no two people have the same data.

works with whoop, oura, apple watch, garmin, anything that syncs to apple health. one thing i'll say honestly, it doesn't do deep per-person learning yet like "coffee doesn't affect YOUR hrv specifically," that's the roadmap, right now it builds fresh plans daily off your actual metrics.

it's live on the app store, has a free trial, small user base so far, mixed feedback which is why i'm here lol.

what i actually want from you guys: does this solve a real problem for you or is "tells you what to do" not actually what wearable people want? what would make you actually pay for something like this? and what's missing that would make it a no brainer? and also would you guys in this subreddit  use ti?

Thank you for your help. Check it out if you like https://apps.apple.com/us/app/rizeai-maximize-your-energy/id6762402079

The idea came up during another family vacation, where we took over 1500 photos and videos over 14 days. We upload all this material to Google Drive and that's it.

The idea is to upload hundreds of photos and short videos from your vacation, and then let artificial intelligence recreate the trip as a coherent 10-15-minute film: animate the selected photos, identify places and events, construct a narrative, add transitions, music, and, optionally, voiceover. The result should be something like a short travel documentary.

I think there's a market for this, what do you think?

Hi everyone! I have a concept for an educational AR (Augmented Reality) game designed to teach children multi-dimensional physics, ecology, and system thinking in a completely intuitive way. I don't have the resources to build this myself, so I'm putting it out there into the public domain. If this inspires you, please take it and build it!

The Core Concept: The Glass Cube

Imagine a virtual, holographic glass cube sitting on a child's desk in AR. Inside the cube, there is a small plant in a pot.

The plant exists in standard x, y, z space, but the game introduces a 4th dimension—Time (t)—and maps it to physical space:

Time Slider: Moving the physical cube (or swiping) to the left rewinds time. The flower shrinks back into a sprout, then a seedling, and finally a seed.

Moving it to the right accelerates time, showing the flower blooming, aging, and eventually decomposing back into the soil.

The Magic: Color Filters (Dimensions of Data)

Instead of teaching kids complex formulas, the game gives them "colored glass lenses" (filters) they can look through. Each lens represents a different physical dimension/property of the simulation:

The Blue Lens (Moisture & Fluid Dynamics):

Looking through this shows water molecules flowing. Kids can see the soil dry up as time moves forward, water evaporating from the leaves, and eventually forming a tiny rain cloud at the top of the cube.

The Red Lens (Energy & Thermodynamics):

This lens visualizes heat and metabolism. The plant glows red when absorbing sunlight. If the child brings a virtual heat source (like a candle) near the cube, they can watch the heat transfer through the glass in real-time.

The Grey Lens (Structure & Material Density):

This visualizes structural integrity. When the plant is watered and healthy, its stem is rigid and dense. If it dries out, the density drops, making it fragile and prone to snapping if the cube is shaken.

Unleashing Childlike Curiosity (The Sandbox)

The magic happens when kids start mixing these dimensions. They aren't bound by strict levels or pre-made scenarios. They can play like "mad scientists" in a safe sandbox:

What happens if I freeze time (t=0), turn the temperature to maximum (Red Lens), and shake the cube?

What if I flood the cube with water (Blue Lens) and fast-forward time by 100 years?

By interacting with these invisible forces visually, children will develop an intuitive, deep understanding of cause-and-effect, thermodynamics, and fluid dynamics before they ever have to memorize a single formula in school.

Why AR?

Using AR glasses or a tablet, the simulation can interact with the real world. The virtual "rain cloud" created by the plant's evaporation could escape the glass cube and float up to the child's actual ceiling, or the virtual plant could react to the real light levels in the room.

License: This idea is 100% Open Source / Public Domain. Feel free to copy, adapt, or build this into a commercial or non-commercial project. I just want to see a game like this exist in the world to help shape the next generation of Einsteins! 🚀

Need some opinion on my side project. I love sending postcards and I collect them everywhere I travel. But I never manage to mail them from the actual place. They come home with me, and mailing them later from my couch defeats the entire point of a postcard. So I built the digital version that keeps the constraints instead of removing them. It gives users the novelty of sending postcards at convenience, yet giving the authenticity of sending it from the exact location (like a real postcard).

How it works: This is a webapp where you can only write a postcard while you're actually there (in neighborhood). It gets postmarked with the approximate location, date, local time, and that day's real weather, and the postmark can't be faked. Then it takes 3 to 5 days to arrive, on purpose. The recipient gets a sealed envelope digitally, breaks the wax seal, and flips the card over to read it (on phone/laptop). No app or account needed on either side.

Not sharing the link just yet, polishing a few rough edges this week.

Sharing some screenshots.

This is not a promotion post. Would love your honest take: is this something you'd actually use, or does it stay in side project territory?

I recently got a bidet but I dont think water is quite enough to clean down there ALL the time. I do use baby wipes but I would like a more "fresh" feel than something for babies as even then you have to shower them after wiping eventually. I want to cut the middleman out and have a baby wipe like product that has soap on it so I can properly clean myself on the go without showering. I know there are body wipes but those are too big, just something the size of a baby wipe that has some soap on it with the same hydration of baby wipes. Preferably if they're fragrance free and not irritable for sensitive skin. If there is a product like this please recommend (not baby wipes).

Ive seen robot lawnmowers and seen them charge from a solar charge point but thought instead the solar panels could be on top of the robot itself. It could be left outside and charge off the sun while not in use ready for the next time its needed. Get it to park in the sun and manage the lawn in an automated way and park out the way when done.
