Multimer

I created this app for myself, because every existing app had pre-built routines that do not adapt to what I was looking for. Also I like watching videos while exercising and most apps do not allow split-screen mode.
I have been using it for a couple of weeks now, and I find it really useful. I hope I can help other people with their exercise routines or other routines that require time tracing.
It is free and currently available in the Google Play Store for Android. I am planning on releasing it for iOS if it has good feedback! :)
Feel free to ask for new features, if they make sense and add value to the users, I will add them right away.
