Finish and move on - Mark it complete, then choose your next focus. 4. Be honest with yourself - Did not finish? Carry it forward or let it go, but you have to decide. ------ FEATURES * One task at a time * Daily focus screen * Streak tracking * Calendar view * Progress tracking * Light and dark mode * Adjustable text size * No account required ------ BUILT FOR * People who feel overwhelmed by to-do lists * People who start but struggle to finish * People who want clarity, not complexity ------ NOT FOR * Complex project management * Team collaboration * Full task lists and planning systems ------ PRIVACY Your data stays on your device.

About

Orbit

Set a timer, put the phone down, and actually stay off the apps that pull you away. Orbit is a focus timer built for ADHD brains that set timers and then ignore them. Most timers just count down in the background. Orbit shields your distracting apps for real, using iOS Screen Time, so the pull is gone while you work. A single hand-drawn tangle of line sits on a black screen and slowly threads with color as your session runs. It is your clock, your progress bar, and something calm to rest your eyes on instead of a feed. Touch it and the strands spring and swirl back into place. Why it fits an ADHD brain: - One tap to start. Pick a preset and you are focusing, no setup wall. - Real app blocking, not a nag. The apps you choose stay shielded until the session ends. - A calm, no-shame stop. Sessions wind down gently instead of slamming shut on a hyperfocus. - Focused days, not guilt streaks. Orbit counts the days you showed up and never punishes a miss. - Nothing to read while you focus. Black screen, one moving thing, silence. Free forever: - Focus sessions with the live tangle - A basic streak of your focused days Orbit Pro: - Unlimited sessions and full app blocking - Complete history and insight into where your time actually goes - Home Screen and Lock Screen widgets No ads. No account. Works offline. Your session data stays on your device. Untangle your time. Terms of Use: https://readbuildship.com/apps/orbit/terms
