Yata! really is just "another timer app." It is extremely simple to use and anyone can figure out how to work it in seconds. When one first opesn the app, the default time is 10 minutes. There are 3 increments of time that can be added or taken away: 5 minutes, 1 minute and 10 seconds. That's it. No using a keyboard or adding the time yourself just press one of the 6 buttons (3 for adding, 3 for taking away) and press start. This simple method works great for shorter times but it can be tiresome and take an unacceptable amount of time to get longer limits. For example, if I wanted to get a timer of 2 hours (for cooking) it would take 23 clicks to reach 2 hours. The app can run in the background and a notification appears in the tray when your time runs out. Overall, it is a simple and effective countdown timer, for shorter times. Four Stars.
