☆☆ Powerful, Simple, Fastest & Ergonomic ☆☆ Instant ON! Fastest on the App Store!! Ready for iPhone 5 Simple & Settingless! Just know what you want! Everything just works! That's why it's also called "j"Light! Features: ✓ Intuitive & simple design, no accidental touch ✓ Fastest on & tiny size ✓ Screen light(real brightness change & instant on) ✓ Strobe & SOS(International Standard) ✓ Self-learning auto power-off Detailed description: Only 1 button for accessing: ✓ Tap to switch on and off. ✓ Press&hold to light up until release. ✓ Double tap for strobe and SOS. Auto power-off(screen) after leaving it unused for 5 minutes under torch mode, but won't disturb you when using! Strobe & SOS frequency is adjustable! These functions are rarely used and will keep hidden to prevent any accidental operation. Light up very fast "every time" you start it! Other similar apps might tell you fast but actually only since 2nd start! They hide in background consuming memory space, just waiting for 2nd start. jLight stops everything when it is not on screen! (Please note that double click home button will show iPhone's task list, the list shows not only "app running in background" but also "recently opened apps". jLight is the latter!) Screen light has 2 colors(red/white) and 5 brightness strength. The brightness is changed for real! Not just change color "from black to red" or "from black to white". Red light can be used for astronomy or any time when night-vision should be kept. White color is for the situation that torch mode is too bright. After 20 minutes the screen will start to blink. That means auto power-off is going to work. If the screen was tapped at this moment, you will get another 20 mins to use, and next time the auto power-off will be triggered only after the total time you use at this time. Moreover, when the battery level is below 20%, similar procedure will be triggered to keep your iPhone from running out of the battery. The only way to run out of the battery at this mode is only when you insist! (If you want to reset the setting, please delete jLight and download it again from the App Store) (Because of iOS limitation, before exit please tap the "reset brightness" button. If you forgot to do this and cause the screen be too bright, just turn the screen off and than switch it back on) A pin is also provided to let user can use screen light directly when app is on. Caution! Continued use of the flash may dramatically decrease battery life.
