Nice app. Bug Found: If You change the language a couple of times the app crashes. Besides, only in English the status bar is visible. ---

There isn’t a specific block, isn’t it? fyi there is the [Light Sensor Extension](https://puravidaapps.com/light.php) to get the illuminance… @aylin_mohamed, did you use an extension by accident? If yes, it would be great, it you could give credit to the extension developer… Taifun ---

Unfortunately quite useless if you do not provide any good guide how to use… Also the user is given an option to “calibrate” the device sensor but how on earth should anybody know what value to set? I like the idea but I think the execution is not very good 😕 ---

i will make new update … i will show a sign next to the label text to tell the user if the light is enough or not and provide a better guide as you said calibration is on all other competitor app …can be used only to calibrate with a real light meter device the standard number is value \*1.6 because i use a real device to compare my sensor thanks for your notes 😄 ---
