I love this app but I have a few suggestions:
1. Make the History in a Calendar Format, for an increase in motivation in completing streaks. And each completed day shows a check mark and when you click on the day, it still shows you the information or progress you made for that day.
2. Add a little interval timer aside from the total timer. Every time I see a timer, it makes me push myself harder.
3. Add more motivation voice coaching especially for more difficult intervals.
4. Add a reminder notification. Say remind myself every 10am.
