Changelog / Version 4.2

4.2 - Your personal coach wraps up every session

New AI-generated session summary with strengths, areas to improve, videos of your best reps and recommended work for your next session.

Version 4.2

December 29, 2025

This is one of the biggest updates we’ve shipped. When you finish your training session, your AI coach now looks at EVERYTHING you did and gives you a full summary: what went well, what to improve, and exactly what to focus on next time.


🧠 AI session summary

Until now, FITIZENS analyzed each set on its own. Now it goes much further: when you finish your session, the AI looks at your whole workout and generates a smart summary.

What’s in your session summary?

Full session summary

  • Coach Summary: an overall read of your session written by the AI, as if your coach gave you feedback at the end
  • Your Strengths: what you did well and should keep doing
  • Areas to Improve: specific technical points to work on
  • Overall Quality: your average technical level across the session

Session stats

Session stats

At a glance, every key number from your session: total sets, exercises, total volume, heaviest weight, valid reps and total time.

Videos of your best reps

Best reps videos

The summary gives you direct access to the videos of your best reps of the session. You can see exactly what you did well and replicate it.

Key focus point

Key focus point with evidence

The AI picks ONE key thing to focus on. Not an endless list of corrections, but the single most important thing for your progress right now. It includes:

  • A clear explanation of why it matters
  • Evidence videos showing the reps where the issue is most visible
  • “Recurring” badge if it’s a pattern that shows up repeatedly in your technique

Recommended work

Recommended work

Based on your analysis, the AI suggests specific exercises to work on in your next session. Every exercise comes with:

  • Recommended sets and reps
  • The “why”: how that exercise will help you fix your weak point

No more guessing what to do next: you get a concrete plan.


🌙 Dark mode, refreshed

New color palette optimized for OLED screens: purer blacks to save battery, better contrast and vibrant colors that keep the FITIZENS identity. Great for training in low-light gyms.
