This is the free but full version of the app with the same name. It has over 11 different functions that transforms your phone into a light yet reliable toolbox. Some of them use the sensors in your device and for this reason the results might be slightly different from one phone to another, depending on its quality.
The functions are as follows:
1) A calculator, useful for anyone that has to deal with numbers from time to time.
2) Flashlight - it turns your full-size screen into a torch! It also can flicker in different colors and at various speeds.
3) Bubble level - to measure angles, letting you selecting a reference (horizontal, vertical etc)
4) Alarm - a reliable alarm clock that wakes you up using a different ringtone every time, from the ones you have in your cellphone
5) Compass - feeling lost? Have a look and find where the North is. Or South, East or West for that matter.
7) Recorder - audio records up to 60 minutes at a time.
8) Ruler - in inches and centimeters
9) Accelerator - shows how fast you device is going.
10) Countdown - baking something and want to be sure you won't forget about it? Use this timer!
11) Counter - perfect to count the sheep when you go to sleep.
It you like the app and want to support me you can buy the pro version. It has the same functions, but is a bit smaller, it requires less permissions and it has no ads.
Made it compatible with tablets, fixed some bugs.
