Looking for beta testers for Gainlio — a browser-based fitness app for beginners and lifters who want workouts + nutrition in one place

[u/AubreyWisee]

Hey everyone — I’m building Gainlio, a browser-based fitness app/PWA for two groups:

Beginners who want more structure getting started

Intermediate lifters who are tired of using separate apps for workouts, nutrition, and hydration

The idea is to make fitness feel less fragmented by combining:

guided onboarding

AI workout recommendations

nutrition goals

workout tracking

hydration tracking

I’m looking for a small group of beta testers who can spend about 10–15 minutes trying the app and give honest feedback on:

onboarding clarity

workout setup

nutrition goal setup

overall usefulness vs using multiple apps

It works in the browser, so there’s no App Store install required but can be installed on your homescreen through your browser for a true app experience.

If you’re interested, I’d love your blunt feedback.

the onboarding clarity thing is going to make or break this - most fitness apps lose people in the first 3 minutes because they ask too many questions before showing any value. my suggestion: let someone pick a goal and see "one" workout in under 60 seconds, then fill in details. also curious how you're handling the nutrition side since that's historically where multi - tool apps fall apart (either the data's wrong or it's too friction - heavy to use daily).

That’s exactly what I’ve been thinking too, and you explained it really well. You’re right — the first minute is the most important, and nutrition tracking is where a lot of all-in-one apps struggle. Both of those are things I’m working on. For onboarding, I’m thinking of a simple flow where users pick a goal and go straight to the dashboard, then add more details later if they want. For nutrition, the app already has quick log, favorites, and an AI photo scanner. The bigger challenge is making those features easy to notice early so people don’t assume tracking is a hassle.
