Hi HN,

I just launched Fitspire, a small iOS app built around one idea: workouts shouldn’t require 45–60 minutes to be effective.

I’m a builder, and like many people working long hours, I found it hard to stay consistent with traditional fitness routines. Most apps felt either too intense, too time-consuming, or overloaded with features.

So I built Fitspire around:

1. Structured 5-minute workouts 2. Minimal, distraction-free UI 3. Simple progress tracking (streaks, reports, history) 4. No subscriptions at launch (100% free for now)

The goal isn’t to replace full gym training — it’s to reduce the friction of starting.

Tech stack:

1. Built with React Native 2. Backend with Firebase 3. iOS release via App Store

I’m mainly looking for feedback on:

Does 5-minute positioning make sense? What would make this actually sticky? Where do fitness apps usually fail in retention?

Would appreciate any honest feedback — especially critical ones.

Thanks.
