ISO of someone who can help me develop an app and website. I have an idea that I want to make come to life and can handle all of the business side of things.

Serious inquiries only. Will setup a meeting for an overview discussion.

I have been trying to develop some APKs. From what i have heard, Flutter is good for its UI and Efficiency and for all other stuffs React Native is good. IF someone have experienced anything about those. Please Suggest me something,i personally think React Native would be a better choice as i am from web development. Thanks!

I'm getting ready to post an RFP for a fixed-fee dev build and wanted a gut check from people who actually do this kind of work before it goes out.

It's a real-time multiplayer app (think social game, players in a shared room, live score sync, sessions that can run over several days instead of one sitting).

Building it web-first (React/Vite + Supabase for auth/db/realtime), then wrapping it for iOS and Android with Capacitor, with Stripe on web and native IAP on mobile.

Budget I'm working with is $16–26k fixed fee for the whole build (web + native wrap), paid out over milestones. Timeline is roughly 3 months, kickoff to app store submission.

Trying to figure out before this goes live:

Does that budget range seem reasonable for this scope, or am I off somewhere?

Is 3 months realistic for one dev or a small team, especially with native IAP in the mix — that's usually the part that eats time. Any concerns with Supabase Realtime for this kind of multiplayer sync at small-medium scale?

And is fixed-fee + milestones the right structure here, or would you expect to bid this hourly instead?

Not trying to lowball anyone, just want the numbers to be realistic before real people are quoting against them.

Thanks!

How do mobile teams detect performance issues that only happen on certain devices, OS versions, or network conditions?

Some users may experience slow loading, freezing, or failed screens while the app works fine for others.

Do you segment monitoring by device model, OS version, app version, region, network type, or user session behaviour?

Interested in how developers identify these hidden performance problems before they become widespread complaints.
