What devices can I use AlzLife on?

AlzLife is available for all iOS devices running iOS 11 or later. However, to use the light therapy part of this application your device refresh rate has to be at least 120Hz (screen is updated 120 times per second). At this time, devices with 120Hz refresh rate include iPad Pro released since 2017 (Here are links to least expensive iPads released in 2017: iPad Pro 10.5 and iPad Pro 12.9).

All other devices (including all other iPhones, iPads, Android devices, and laptops) have refresh rate of 60Hz. Devices with refresh rate of 60Hz are only able to generate maximum light frequency of 30Hz. Frequencies less than 40Hz have NOT been shown to produce the same effect in regards to the clearance of amyloid beta protein.

In other words, it is not a software problem. It is a hardware limitation. The minimum necessary refresh rate is 80Hz (one white frame + one black frame 40 times per second = 80 frames per second or 80Hz). This refresh rate is only available on iPad Pro 2017 or newer.
