Tap "Knok" once a day to check in. The people who watch over you see at a glance that you're fine. If someone you watch hasn't checked in within their chosen window, you'll know to reach out. HOW IT WORKS • Tap Knok to check in — that's it. • Add the people you care about. When they accept, you watch over each other. • Everyone appears as a simple traffic-light tile: green (recently checked in), amber (due), red (overdue). • Set your own check-in interval and quiet hours, so you're never nudged at the wrong time. Each person's time is shown in their own timezone. WHO IT'S FOR • Older parents and their adult children staying in touch. • Friends and family who live alone. • Anyone who wants a low-effort way to say "I'm okay" without a phone call. UNLIMITED (OPTIONAL) • Free plan: fully see your first 4 contacts. • Unlimited subscription: watch over everyone in your circle, no limit — 4.99 USD/month (local pricing shown in-app for your country). Auto-renews monthly until cancelled; manage or cancel anytime in your App Store account settings. PRIVATE BY DESIGN • No social feed, no ads, no tracking. • You only ever share your status with the people you approve. • Delete your account any time, right from the app — it removes your data and frees your number. IMPORTANT knokkeroo is a personal check-in and communication tool. It is NOT a medical device, emergency response system, or a substitute for professional or emergency services. If someone is in immediate danger, contact your local emergency services right away. Terms of Use (EULA): https://www.odderonphi.com/knokkeroo-terms ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Unlimited | $4.99 | per month | ## Version history (last 5 releases) ### 5.7.34 — 2026-08-28 • Widget fixes: the widget now always shows your true check-in status. No more false "Verification needed" while you're signed in, and no more out-of-date colour after you check in with your shortcut. • Tapping the widget now records your check-in even when the app hasn't been opened for a while. • Your music keeps playing. The knock sound used to take over your phone's audio and pause whatever you were listening to. It now plays alongside it. • The Back button at the top of a screen is now on the right, on every screen. ### 5.7.28 — 2026-08-23 Better visibility for everyone: the quiet hours moon, the lock on locked tiles and the saved check-in message are now clearly readable in both the light and dark looks, and the home screen widget always matches your chosen look, updates instantly, and clears itself when you log out. Apple Watch pairing now uses a simple 6 digit code shown on the watch, plus a clearer contact settings layout, a tidier profile screen, and the settings back button within easier reach. ### 5.7.16 — 2026-08-22 You may be several versions behind, so this update brings all of it at once. • Tell them you're okay, straight from their card. A new "Tell them I'm okay" button on a contact's settings screen sends that one person a reassuring message and checks you in for everyone watching you, with a quick confirmation before it sends. • Light or Dark, your choice. Open Me → My settings → Appearance. Many people find the light screen easier to read. • See what a widget actually looks like. When you open this version, we show you a picture of the knok button as it appears on your Home Screen — and on your Lock Screen, where you can check in without unlocking your phone. Simple steps follow the picture. • Green, amber and red no longer rely on colour alone. Each contact now carries a small mark as well as a colour, on your tiles and on the widget. • Easier to read and easier to leave. Clearer check-in times, tiles that line up evenly, and a Back button at both the top and the bottom of the settings screens. • Add someone straight from your phone's contact list, instead of typing the number. • Fixes: a check-in saved while you were offline no longer swallows the one you make afterwards, and the app recovers properly when the network is slow. knokkeroo is a personal check-in app. It is not a medical or emergency service. Questions? hello@knokkeroo.com ### 5.0.0 — 2026-08-11 knokkeroo 5.0.0 — sharper and more reliable. • A clearer, redesigned terms screen. • The home-screen widget keeps your colour (green, amber or red) instead of resetting. • Subscription support improvements, plus many small polish and reliability fixes throughout. ### 4.39.8 — 2026-08-10 knokkeroo 4.39.8 — easier to see, easier to answer. • Your favourite contact's latest check-in time now shows on the widget, exactly as in the app, and tapping them opens their page. • Someone checking in on you? Press and hold the notification and tap "knok now" — no need to open the app. • A clear Back button at the top of every screen, so you always know how to get back. • Setting a favourite now reaches your widget immediately, plus clearer text throughout. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
