Description

From the listing uploaded by “emilnet87ii”.

Does jet lag get you down every time you travel across time zones? Are your sleep patterns off the chart? Researchers at Stanford University think they have a solution. They've found that brief, frequent flashes of light while you sleep resets your circadian rhythm. An hour of intermittent light flashes while sleeping shifts your "sleep" clock by 2-3 hours. Jet Lag Buster leverages this cutting-edge research to provide similar flashes (Camera Permission is required!). The App: Use dropdowns to select your travel time zones; the app will calculate the flash profile. Override it, if required. If flying east, set flashes for early in the morning (just prior to waking); if going west, set flashes for the period just after you fall asleep. Set it up on the night prior to your flight, then wake up ready to take on the world! Go get 'em, tigress.

Jet Lag Buster APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Jet Lag Buster APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 258851e7c7256edc6b70df6bf6f45270.
