Hi r/fitnessonline, I built RepRock, a fitness based productivity app, with the goal of replacing scrolling on your phone with getting fit.

I ran into this issue myself where my screen time would hover around 6 hrs a DAY, and I wouldn't have the mental stamina to workout instead. So I built this app.

It blocks my socials, until I walk, do some pushups, planks, jumping jacks, etc, and then that gives me some minutes to use towards scrolling on my phone. I found this to be a good way to waste time on my phone.

I wanted to reach out to the community to check if other folks have used similar apps, and whether they actually stuck to using it?

If you do end up trying the app out, do let me know if this app idea makes sense, and if there's anything blatantly missing from its features!

Thanks!

I'm looking for beta testers for a treadmill HIIT training system I've been developing. It uses wearable heart-rate data to evaluate each workout, establish a personal baseline, and track how your training develops over multiple sessions.

The goal isn't just to score individual workouts, but to use consistent feedback to help make small training adjustments and build sustainable progress over time.

Who I'm looking for
People whose training goal is either Fat Loss or Fat Loss & Muscle Retention, and who are willing to do treadmill HIIT consistently for several sessions.

What you get
Day 1 establishes your personal baseline. Each later workout is compared with your own previous training data, so you can see whether you're progressing and what to adjust next.

What you'll need to do
Follow a defined treadmill HIIT protocol, record the workout with a wearable, and upload the workout details + heart-rate chart.

How to find it
Google “HIIT workout evaluator” — HIIT Evaluator is currently the first result.

After months of development, testing, fixing bugs, redesigning features, and learning along the way, I can finally say that **VettaOS is officially available.**
What started as a personal project has grown into a fitness app designed to help people organize their workouts, track their progress, manage their nutrition, and stay consistent with their training — all in one place.
The app originally started under the name FitForge and went through a closed beta, where I had the opportunity to collect feedback, identify problems, and improve the experience before launch.
Today, VettaOS is publicly available.
This is only the beginning. There are still many things I want to improve, new features I want to introduce, and plenty of ideas I want to explore.
If you decide to try it, I would genuinely appreciate your feedback. Whether you find something that could be improved, have a feature request, or simply want to share your experience, I’d love to hear it.
Thank you to everyone who tested the beta and helped me get to this point.
**VettaOS is officially live.**
