moss vs kSafe
A $59 container with a timer lid. Locks the whole phone away, with no app.
Checked 11 November 2026 against Kitchen Safe's own pages. We make moss, so we have linked every source below.
What kSafe is
The kSafe is a plastic container with a timer built into the lid. You put the phone in, set a time and it will not open until the timer ends. It costs $59 ($69 for the XL), needs no app or subscription and works with any phone, or with anything else that fits. It locks away the whole phone, calls and maps included.
What moss is
moss is an iPhone app that comes with a small physical stone. You choose the apps that distract you, tap your phone on the stone, and those apps stay locked until you tap the stone again. People who live together can link their phones to share schedules and put their phones down at the same time, while each person keeps control of their own phone. Locking is free in the app, the stone is a one-time purchase, and the household features are a paid add-on.

- Works with any phone, Android included, and with no software at all.
- One box holds several phones.
Where moss is better
- Your phone still works for calls, maps, music and anything else you did not lock.
- An emergency does not mean smashing a box.
- Schedules, modes and a household view.
