moss vs Light Flip
A $349 flip phone running LightOS. Reservation only when we checked.
Checked 11 November 2026 against Light's own pages. We make moss, so we have linked every source below.
What Light Flip is
The Light Flip is a flip phone from Light that runs LightOS. It has T9 typing, voice-to-text, 9 speed dials, 5G, a headphone jack and USB-C, and it comes in six colours. It costs $349 unlocked, or from $39 a month on a two-year Light Service contract, and it needs a carrier plan. When we checked it could only be reserved, and Light's page did not give a delivery date.
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.
