Your tracker tells you what happened. Sixteen tells you why, then does something about it.
Connect your Whoop band or your Apple Watch and Sixteen reads what they already measure, then does the part they never do. It finds the reason behind a bad recovery, names the one thing worth fixing today, and locks the apps standing between you and it.
Everything your band tracks, in one place
Recovery, strain, sleep and stress, scored from the band you already own. Connect a Whoop over Bluetooth or an Apple Watch through Apple Health. No new hardware to buy.
Plus the two things they miss
Log a meal with one photo and see your protein, carbs and calories. Track your screen time and focus through the day. The two numbers that move your recovery the most, finally next to it.
It tells you why
A short night is never just a number. Sixteen traces it back to the cause, the late scroll, the midnight meal, the day you overreached, and shows you the one that mattered.
Then it fixes it
When Sixteen sees a weak recovery coming, it locks the apps that would make it worse and reminds you before the damage is done. Distracting apps stay shut until you earn them back, so the phone becomes the thing you protect your health with, not against.
Earn your screen time
Do the work, then scroll. A workout, a walk, a logged meal, a focus block. Every action you take unlocks the apps you love, guilt free.
Built for the people who already track everything
If you wear a band and your scores go up and down while your days stay the same, Sixteen is the app that finally closes the loop.
