moss vs Light Phone III
A separate $899 phone with a camera and a few tools, and no browser, social media or email.
Checked 11 November 2026 against Light's own pages. We make moss, so we have linked every source below.
What Light Phone III is
The Light Phone III is a standalone 5G and 4G LTE phone with a camera and a short list of optional tools, including directions, a music and podcast player, rideshare, an authenticator and a hotspot. It has no browser, social media, email or news. It costs $899 unlocked, or from $59 a month on a two-year Light Service contract, and it needs a phone plan. It has been shipping since March 2025, but a new order is a reservation that Light expects to deliver in late December 2026. Its FAQ says there is no Spotify, Signal or WhatsApp today.
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.
