moss vs AppBlock
Blocks apps and sites by time, place or Wi-Fi network. Android first, with a free tier.
Checked 11 November 2026 against MobileSoft s.r.o.'s own pages. We make moss, so we have linked every source below.
What AppBlock is
AppBlock blocks apps, websites and keywords on Android and iPhone, with browser extensions for Chrome, Edge and Brave. Profiles can switch on by time, day, location or the Wi-Fi network you are connected to, and a Strict Mode can require another person's approval to unlock. On iPhone the free plan allows a quick block of up to 4 hours, 2 schedules and Strict Mode for up to 12 hours. Premium is a subscription, with a lifetime option.
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.
