Well I've made two free, ad-free lesser-known apps with good reviews:)
Meet Me In The Middle - lets you find the middle spot between you and your friend to meet, so that each one of you goes the same distance. It also find nearby restaurants etc.
Learn & Work Scheduler - helps you with managing your time during learning and working. You can add multiple sessions, like reading, or learning math. It reminds you about breaks.
