MorrowVault — product and UI design by tPanel for iOS and Android: one slide a day to say you’re okay, trusted circles with their own timing, and a vault shared only after quiet days.
How tPanel Designed a Daily Check-In Mobile App for iOS and Android
MorrowVault is a daily check-in app: one slide a day tells the people who matter that you are okay, and nothing happens unless the days go quiet. The brief came from a real gap — people who live alone, or far from family, either share live location (which feels like surveillance) or rely on someone noticing a silence (which is unreliable). The product had to reassure without tracking: no location, no feeds, just a gentle daily rhythm.
tPanel designed the product and interface for iOS and Android around three surfaces. The home screen is a single action — slide to check in — with the last check-in time always visible, so users never wonder whether it registered. Trusted circles let each group of people — family, close friends, an executor — have its own quiet-day threshold and its own message, because the right response to silence is different for a spouse than for a solicitor. The vault holds voice messages, photos and letters, each item released to its chosen people only after a set number of quiet days.
The hardest constraint was tone. A missed check-in must never read as an alarm — most quiet days are just a busy weekend — so the app nudges its owner first and escalates to circles only after each group’s own threshold passes. There are no streaks, badges or guilt mechanics anywhere in the interface.
“For an app whose whole job is noticing silence, calm is the feature.”
