When developing Forma, I paid special attention to minimalism. As a result, I got a fully functional workout tracker, which works completely offline and has no extra functions at all. The interface is so intuitive that it is impossible to get lost. I’ve honestly tried my best to make it nice & simple! The app is great for both gym and at home workout, because the list of exercises is created by you. Instead of hundreds of preset workout programs (invented by nobody knows who), you form your own database - leave only what is important for you personally. ‣ Create any exercise: from yoga to strength training. ‣ Customize them: workout with dumbbells, barbells or with your own weight. ‣ Log your results in a few clicks. ‣ Keep track of your progress: stay toned, gain or lose weight. Together with other users who regularly write great reviews, we strive to keep the app simple. As a result, as many superfluous elements as possible have been eliminated from the app, but functionality has been retained. However, if you do miss something, you can always contact me directly from the app and I will try to implement your ideas. The only limitation of the free version is the maximum amount of 8 workouts. You can ignore this limit by deleting old workouts, or remove the restriction completely with a premium subscription at a reasonable price. This kind of support, as well as honest feedback, helps me grow the project. I promise, I do not and will not have any advertising and unnecessary purchases. Everything is extremely transparent. I am using it myself, so I do not want to make another Frankenstein out of the app. Policy: http://gymtracker.tilda.ws/privacy-policy Terms and Conditions: http://gymtracker.tilda.ws/terms-of-use Thank you for reading to the end, so it was not in vain!
