A $249.99 phone-sized ePaper Android device, with Wi-Fi only and the Play Store on board.
Checked 11 November 2026 against Onyx Boox's own pages. We make moss, so we have linked every source below.
What Boox Palma 2 is
The Boox Palma 2 is a 6.13 inch ePaper device the size of a phone, priced at US$249.99. It runs Android 13 with the Google Play Store installed and connects by Wi-Fi and Bluetooth only, so it is not a phone. The slow black and white screen makes video and feeds less appealing. Nothing is blocked: any app from Google Play can be installed on it.
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.

| How you lock | Tap the stone, or start from the app, a Shortcut, the lock screen or the Action Button. Schedules by day of week | It does not. The ePaper screen makes feeds and video dull |

Where Boox Palma 2 is better
- It gives you something else to pick up: a reader that fits in a pocket.
- The friction is in the screen itself and cannot be switched off.
- It works alongside any phone.
Where moss is better
- It acts on the phone you already carry. With a Palma, your iPhone is unchanged.
- It costs much less: moss is US$49 against $249.99.
- A real lock that needs the stone to undo.
