I don't want to make a thread for a single question. So feel free to recommend any app you use and think is useful for your life and/or profession. For example I use "My Piano Assistant" to easily visualize and listen to musical scales, intervals and chords, really handy app. Coursera has also some really cool courses and content.
Now back to my question: Does anyone know an Android app that has a snap grid in wich you can draw straight lines to make sketches and plans, zoom in-out and scroll along the canvas? just like some simplified version of mapster 2D view.
