Angie- Founder of YourApparelI have used this app and you have different characters varying from strict with few breaks to kind with longer breaks. I like this app because you can set different intervals depending on the tasks.
Angie- Founder of YourApparelDifferent take in the pomodoro technique. It has different characters with different levels of strictness to focus on your task. Flip your phone to stay focused. The app will give a signal when it's time for a break. The app deducts points and reprimands you when you pick up your phone early. You can set blocks from 1-8 hours.
