Do app developers even exercise?

Shonan Charlie

Denoted as a simple Ab exercise application. I'm sorry to say this doesn't come close to being simple or useful. Application UI is cumbersome, doesn't apply normal exercise logic patterns, usability is low. Commercial laden and annoying even after paying for extension programs.

Likely a developer project slammed together to grab some unearned profitability from the unsuspecting user. I was connected by then advertisement via the Tanita Health scale and surprised a major company would support this commercially. I would give this negative stars if possible. Needs a serious redesign... back to the whiteboard and done time in the gym would be a plus.

Sit ups


By far the best sit up app on the market. Once you buy the goal setting kit your smooth sailing. This app has helped me learn disipline and hard work and I've only had it for 2 weeks. With this app I've been to go from 1 sit up to 20 by increase my goal every 2 days. Way worth the money for the add ons and thanks to the creators

Great app !!


Great app which do work in making sure the correct way to do sit-up and monitoring the progress. The only the down side of the app is the graphic display and also the design layout. Some app which have great design and graphic display that you can refer like Nike Fuelband, Sleep Time, Digifit etc... Looking forward to the next version :)
