GymStamp - Proof you went

A stamp only gets its color on site.
GymStamp is a ledger for the fact that you went to the gym. It is not an app for filling in the week from memory on Sunday night.
■ You can only stamp on site
Stamping works within 100 meters of the gym you registered. Open the app, tap "Record here", and that exact moment is what gets saved. The same gym can be stamped again after four hours.
■ A stamp only takes color when the place was confirmed
One visit is coral, two or more on the same day turn blue. A day where the location could not be confirmed stays gray on the page. Nothing is inflated, nothing is quietly removed.
■ Log the training, right there
Straight after the stamp, write the exercise, weight and reps (or minutes).
・140 exercises included. The ones you use most rise to the top. Reorder them, hide them, or add your own.
・"Same" repeats your last set in one tap. "History" offers the weights and reps you actually lifted before.
・Notes at three levels - the day, the exercise, the set. Every one of them searchable later.
・A rest timer between sets (60/90/120/180 seconds, or any time you type).
・Export everything as CSV.
■ Work written on site carries a mark
Records written after the app confirmed you were at the gym carry a "verified on site" mark, so they are never confused with entries added later. If a simulated location is detected, the mark is not given.
■ The days you log get a flame on the stamp
Any day with a workout logged gets a flame behind it. The days you showed up and the days you worked sit on the same page, and they look different.
■ Four numbers, and no more
This month, week streak, total days, all time. There is no way to raise them other than going.
■ The only audience is you
No account. Everything stays on your device and is never sent to the developer. Search by gym name, exercise or note - searching your own records runs entirely on your device. Only when you look for nearby gyms is your approximate location sent to a map service, and your records are never sent with it. Location is used only while the app is open, never in the background. Ads are non-personalized and do not track you.
■ Free means one gym
The free plan registers one gym. If you later change or remove it, that gym's stamps, visits and workout records are all deleted, and it cannot be undone (up to twice a month, with a confirmation screen first).
On the free plan, nearby gym search is limited to 15 times a month while you pick your first gym, and 5 times a month when you change it.
This app is built for people who keep going back to the same gym.
■ What the one-time purchase removes (three things)
Ads disappear. You can register any number of gyms, and every gym keeps its records. Nearby search is available 50 times a month. One payment, no subscription.
Workout logging, the rest timer, CSV export, search, the flame and the share card are all free.
■ Also
Dark mode follows your device setting. Export your data to a file and load it on a new phone. On Thursday evening, if the week is still empty, GymStamp says so (optional). 24-hour gyms and other large chains are supported; anything missing from the map you can register yourself.
