Mortise is a small, private app made by Hadger. If something isn't working, or you have a question, email hadger.support@gmail.com and we'll help.
Where is my data? Only on your two phones. There is no server and no account, so we cannot recover a lost report — and no one else can read it either.
Do both people need the app? Yes. Each person answers on their own iPhone, and the results cross phone-to-phone. You can also try the built-in sample report on one device.
Is it really free? Yes — no subscription, no in-app purchases, nothing to cancel.
