About this app

Gymmons is a collectible fitness app: every check-in helps you and your group hatch eggs, evolve creatures, and advance in the league.
Train, track your progress, and turn every active day into a lasting reward.
Invite your friends to a private league and evolve together.

What you can do:

• Log workout activity, duration, and notes
• Add photos to check-ins
• Track XP, eggs, evolutions, and your collection
• Track streaks, achievements, and progress
• Join private leagues, automatic battles, and a feed with your group

An indie project, made with love:

Hi! I’m Marco, the developer of Gymmons. I’m a solo developer building the app I’ve always wanted to help me stay active. Every screen, rule, and creature passes through my hands, so the app grows a little with every update.

This first version starts with a smaller selection of creatures so I can test, improve, and care for the experience together with the community. The collection will expand in future updates.

Transparency about the artwork:

Drawing more than 100 creatures takes time and, as a one-person team, I haven’t finished them all yet. While I finish the illustrations, some images in this version are AI-generated and used only as temporary placeholders. They do not represent the final art direction: all AI-generated artwork will be replaced by original hand-drawn illustrations by me and/or invited artists, always with proper credits.

Your feedback at this stage is worth gold. If something breaks or you have an idea, let me know! :)
