Simple app to help you follow ab routines made by Dominic Sky. It contain three routines of different difficulty for you to choose from. All the routines were introduced by Dominic in his video Deadly Ab Routines and I took the video and made an app which not only tells you what exercises to do but also shows you how to do them.
And on top of that it can keep track of time it took you to finish the set and how many sets you already did. Oh and by the way... There is a dark mode ideal for people with AMOLED displays.
The app is completely free, with no ads (only abs) and open source. You can see the source code on Github: https://github.com/lsrom/DeadlyAbRoutines
