StopIt

StopIt blocks distracting apps when you need to focus. It includes a Pomodoro-style focus timer (25 minutes on, 5 off, or your own rhythm), and the apps you picked stay locked for the whole cycle, breaks included, so a "quick break" never turns into 30 lost minutes.

StopIt uses the Accessibility API to detect when user-selected distracting apps are opened and to immediately show a blocking screen while a manual lock, timer lock, or routine lock is active. It may also detect uninstall attempts during an active lock to reduce lock bypass. This access is used only for core app-blocking and lock-maintenance features, and is not used for advertising, profiling, selling data, or sharing data with third parties. If the user turns on short-video blocking, StopIt also checks whether a short-video screen has opened in the video apps the user chose, using only the identifiers of on-screen elements, and sends the user back to the previous screen. It does not read on-screen text or message content, and does not send it off the device.

StopIt uses Android's VpnService for its website blocking feature. It is a local, device-only VPN that filters DNS lookups: requests for the websites you selected are blocked, and every other lookup passes through unchanged. It runs only while a lock is active and never connects to a remote VPN server. StopIt never shares DNS queries or browsing history, and never sends the names of blocked sites to its developer or any third party. To show in your lock history which of your selected sites were blocked and how often, it keeps that record on your device only, for 30 days, and leaves it out of backups and device transfers. Once a day it sends usage statistics with only count ranges (for example, 1–5 blocked attempts on 1 site), never site names. Traffic from other apps is never intercepted or monetized.

Select the apps that break your concentration, then lock them instantly, by timer, or on recurring routines. Instead of only reminding you, StopIt is built to block access when you actually open the app.
