I work in a gym where memberships were still managed manually.
Every time someone wanted to renew, staff had to open profiles manually, change expiration dates by hand, handle cash, and deal with mistakes like forgotten renewals or incorrect dates.
So I built a local desktop app for gyms that:
- works with existing barcode cards
- instantly validates memberships
- allows 1-click membership renewal
- supports monthly / 6 month / yearly plans
- automatically calculates expiration dates
- prevents manual date mistakes
- works offline locally on the PC
- can be customized per gym
The cool part is members don't even notice the transition because they still use the exact same cards.
Currently testing it in a real gym environment and it’s working surprisingly well.
Would love feedback from gym owners or people working in fitness businesses.
The app is currently in Croatian because it's being tested in a local gym, but I can easily switch the entire UI to English or customize it for different gyms.
