Questions, answered.
Do I need an iPhone Duo?
No. On iPhone Duo the hinge measures the angle directly. On any other iPhone, Angled uses tilt mode: press the edge against a surface to measure, or lay it flat as a level.
How accurate is it?
For the best result, use Zero here on a level surface first, then rest one half flat while you measure.
How does the Daily Angle work?
Everyone gets the same target angle each day. The reading is hidden, so you fold by feel, lock it in and see how close you got. Play every day to build a streak.
What do I get with Angled Pro?
Unlimited saved readings and more colours, as a one-off purchase. There is no subscription.
Does Angled collect my data?
No. There are no accounts, analytics, ads or tracking, and your readings never leave your phone. See the privacy policy.
How do I restore Angled Pro?
Open Settings in the app and tap Restore Purchases.
When does the Daily Angle change?
At midnight, your local time.
