Measure the light levels of your surroundings. Featuring min and max levels and real time graphs, this app is all you need for your measurements.
 

 

New in 1.1.0:

• Time period in graph can be changed between 80s, 800s, 1h, 5h, 10h and 24h
• Screen saver to prevent screen burn-in on longer measuring periods
• Online ranking for brightest things (o_O)

New in 1.1.1:

• Fix false readings
• Fix graph inaccuracy with low values

Important! The light sensor on cell phone can’t match the accuracy of any real measuring equipment. The app shouldn’t be used in any professional measurings.
