I'm looking for a countdown app for Android that:

• displays hours and not days
• countdowns till at least 100h
• doesn't show ads in countdown
• doesn't display some event name that can't be configured (eg "birthday"): I'd like to either not show any event name, or write it down myself.

Preference for a gratis application.

What I've tried so far:

1. https://play.google.com/store/apps/details?id=com.jupli.countdowntoanything shows days:

2. https://play.google.com/store/apps/details?id=me.gira.widget.countdown displays days:

3. https://play.google.com/store/apps/details?id=me.gira.widget.countdown has ads unless one pays for the premium version:

4. https://play.google.com/store/apps/details?id=com.BirthdayCountdown only specializes in birthdays:

5. https://play.google.com/store/apps/details?id=de.kempmobil.timer and https://play.google.com/store/apps/details?id=at.cwiesner.android.visualtimer only go up to 24 hours.
