I have never written a review before. However, this app has changed my life. I have ADD. When I tried to study before I used this app, I had to spend an unsustainable amount of time to complete my work. This was because I was constantly getting distracted. Now, when I work, I always have my cell phone out on my desk with this app going. For me, distraction always starts with me looking up and around. Now, when I do that, I see this app’s “focus session” screen counting away. Then I remember that I am on “focus” time, and get back to my task. Also, knowing I have a guilt-free break coming up makes me not rebel against focusing for 25 minutes. The knowledge that I will have time to get important things done besides studying motivates me. I recommend getting the pro version. Being able to adjust the time for breaks is essential for me. I am a mother, so the things that I used to try to multitask, I now do one at a time during my breaks. Sometimes, I need more than 5 minutes to finish the dishes, etc. I can adjust the time of each break on the “break screen” with pro. It takes 2 seconds. Setting my chores, studying, etc up this way takes away the excuse that I had about needing to do chores or other important things instead of studying. Because this app prevents the screen from locking, it never disappears like the regular timer app on my phone. I don’t have to reset it each time a session ends either. It is all automatic. Resetting a timer over and over on my own would never have worked with my ADD. I don’t think I conveyed how much this app has changed my life. It is a night and day difference.
