iOS-> Android – need equivalent help

Just moved from iPhone to Android phone – there are few apps that I miss – appreciate if anyone can recommend similar apps
1. Remind Me to Call – Loved the simplicity in which it does the work – anything like that (looked at few but they have too may things or not simple)
2. Chimes – Again a simple app that speaks the time at every hour. What I could find so far on Android are ones that would play a sound but not speak the time (which do not work when there are so many other reasons for the beep to go off). 3. Integration of Lotus Notes calender on same calender default calender – this could be related to how to configure. Notes did not work under default email setup – so had to Install Notes Traveler – which then does everything in its own apps (which also are multiple). 4. Email reader (default) that gives a bubble ‘counter’ with unread messages.
TIA
