Too quiet

Alarms volume is too quiet, cant hear them with traffic, music and other noises drowning them out. Also, police alarm? Not a good choice. Do you run? Run faster, stop, lay down? Jump off a bridge?


The smartest timer app ever

This app is so easy to use and so smart. It has all you need to create simple or complex sessions. I absolutely love it. One improvement greatly needed is the volume of the warning tones. On the iPad the tones are very difficult to hear even with the volume turned up all the way. Also the range of sounds is very limited. So a hgher volume and more tone alert types would make this app the best in its class.

I have a GymBoss but the screen is very poor and setting up with the GymBoss is not as as smart as the app. Please make a gym boss that has all the ease of use and the clear screen of teh iPhone and I will gladly buy one and use it instead of this app.


Worth the wait

Having used the old version of this app I was expecting a Bette version. Well the new version is far better then the last and the stop watch application works a treat. It's easy to design your own timers and unlike the last version you can edit your intervals in a very easy to do and uncomplicated way. Plus the option to repeat and add Laps is a bonus. All up I rate it 5 stars. Great job guys
