One purchase, no subscriptions, no recurring fees.

Your intentions, anchored where you can’t miss them. CognitiveAnchor turns the thing you’re trying to remember into a living presence on your Lock Screen, Dynamic Island, and Home Screen — so “don’t forget” becomes “can’t forget.” No accounts, no cloud tracking, no clutter. Just a calm, glanceable anchor for what matters right now. WHY IT WORKS Out of sight is out of mind. An Anchor keeps your task visible with a color, an icon, a live countdown, and a subtle animation — the kind of persistent, ambient cue that actually changes behavior instead of buzzing once and disappearing. WHAT YOU CAN DO • Live Activities — watch an Anchor and its countdown live on your Lock Screen and in the Dynamic Island. • Home Screen & Control widgets — start your favorite Anchors in a single tap. • Walk-away failsafe — set an on-device geofence and get a time-sensitive alert if you leave before you’re done. Perfect for the oven, the laundry, a parking meter, or a child in the car. • Countdown timers with early warnings — a heads-up before time runs out, not just after. • One-tap parking — launch Pango, CelloPark, ParkMobile, or EasyPark with a live timer already running. • Ready-made templates — medication, EV charging, deep-focus sessions, baby feeds, watering plants, the oven, laundry, tea, hydration, naps, and more. • Make it yours — pick the icon, color, duration, and animation for every Anchor. • Accessibility built in — color-blind-friendly palettes and full support for six languages (English, Hebrew, Spanish, French, German, Korean). BUILT FOR People with a lot on their mind — parents, students, people with ADHD, shift workers, cooks, EV drivers, and anyone who’s ever walked away from something they meant to finish. PRIVACY BY DESIGN Your location never leaves your device — geofencing is handled entirely on-device to power local reminders. No ad tracking. No analytics profiles. Anchors you choose to share travel through your own iCloud. PREMIUM (one-time unlock, no subscription) Upgrade once to run up to four Anchors at the same time, unlock every premium template, and create free-form custom-text Anchors. Includes Restore Purchases; your unlock is yours to keep. Anchor your attention. Finish what you start.
