Checked 11 November 2026 against Cement Planet LTD's own pages. We make moss, so we have linked every source below.
What FocusFlight is
FocusFlight is a focus timer that shows each session as a flight between cities. Its Airplane Mode blocks apps and sites through Screen Time while the flight is in the air. The App Store lists All-Access at $3.99 a month or $18.99 a year, and Lifetime at $18.99, $19.99 and $33.99, so check the price in the app. It runs on iPhone, iPad, Mac and Vision, and needs iOS 17 or later.
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.
