Minder turns your phone into a pair of eyes that watch you work. Prop your phone up, slide to focus, and get to it. The eyes stay with you: they blink, glance around, raise an eyebrow, look proud when you've been going a while, and get very suspicious if you pick your phone up mid-session. It's body doubling for people with ADHD, or anyone who works better when someone's watching. A black screen, two eyes, and a reason to keep going. FREE, AND BUILT TO BRING YOU BACK โ€ข Slide to focus; a timer and gentle check-ins every 15, 25, 45 or 60 minutes โ€ข A daily goal ring and a streak, with one Streak Shield every month for the day life gets in the way โ€ข A monthly challenge to chase, with a trophy when you get there โ€ข Tag each session (Work, Study, Read, Write, Create) and plan it: open-ended, 25, 50 or 90 minutes โ€ข A 5-minute break when you finish, while the eyes doze off too โ€ข A Lock Screen and Dynamic Island timer while you focus โ€ข Widgets for the Home Screen, Lock Screen and StandBy; tap one to start focusing โ€ข A Start focusing control for Control Center, the Lock Screen and the Action button (iOS 18) โ€ข Brown noise to focus to, made on the phone โ€ข Your week, and where the time went, by tag โ€ข Siri and Shortcuts: "Start focusing in Minder" and "How long have I focused in Minder" MINDER PLUS (SUBSCRIPTION) Everything in Pro, plus, while you're subscribed: โ€ข Every eye pack (Galaxy, Gilded, Toxic, Blood moon) and the rain and fireplace sounds โ€ข The Eye of the Month: a new look every month, kept in your collection โ€ข 3 Streak Shields and 5 poster credits added at the start of every month โ€ข Insights: your best focus hours, average session, pick-ups an hour and the month as a calendar โ€ข iCloud backup of your focus history, in your own iCloud account Minder Plus is $2.99 a month or $14.99 a year in the US (local prices vary), and the yearly plan starts with a 1-week free trial for new subscribers.
