Flashlight by Rik 4+

The completely free, ad free, advanced flashlight app for your phone with all possible controls in a simple interface optimized for speed.

Averaging 5-star ratings and millions of downloads, this flashlight app is a must-have utility for your phone. It fully remembers its state when you quit, and doesn't have any useless bloated art. Even if you already have a flashlight app beyond the standard iOS widget, my bet is that it wastes your phone's memory and loads slower than this one.

This app transforms your iPhone into a very powerful flashlight using the torch of the rear camera. It works 100% of the time (unlike others), it is exceedingly small and fast loading (unlike others), and is completely free (unlike others). No internet connection used, no ads, no upsells, no marketing, just a flashlight.

FEATURES:
- No ads
- Flash on/off, INSTANT on.
- Complete range of light intensity control
- Any screen size from iPhone SE up
- Emergency Morse SOS mode on shake
- Strobe with complete control over the light AND dark timings (10ms to 2s)
- 40Hz Mode for those wanting to experiment with brain waves
- Morse mode (manual strobe)
- Loads extremely quickly, fastest flashlight on the app store
- Can completely darken your screen for better effect
- No wasteful pretty images
- Remembers its state when in background mode and across restarts

Caveats:
- It is impossible to keep the flash running in the background, iOS forbids it for 3rd party apps.
- This app manages a 10ms strobe speed (100 strobes / second), which is about the best that the devices can achieve.

If you're looking for a flashlight app that just works, loads as quickly as possible, stays in multitasking memory as much as possible for later reuse, or want complete control over strobe timings, this one is for you.

Please note: Continued use of the flash may dramatically decrease battery life
