One habit. 66 days. An AI companion that rings your real phone — sometimes when you least expect it — asks how it's going, and remembers the promise you made on the last call.
the whole ideaEvery habit app you've deleted sent you a notification. You swiped it away at a red light, or from bed, and by the time you were free it was gone. That's not a willpower failure — it's a design failure. A notification asks for nothing.
Hibiko rings. In Turkey that's a real phone call to your mobile number, not an in-app buzz. You pick up, and there's a 30-second conversation on the other end: how did yesterday go? what are you doing today? You can't swipe that away, and you can't lie to it twice in a row without noticing.
The part that does the work: some calls come at times you don't choose. A few times a week, at a moment you weren't braced for, the phone rings. Not knowing when it's coming is what keeps the habit parked in the back of your mind all day — which is precisely where a habit needs to live before it becomes automatic.
Hibiko is built for people with ADHD and anyone else who bounces off the spreadsheet school of self-improvement. What's deliberately not in it:
If you want to track eight habits, log macros, see a heatmap of your year, or type at a chatbot — Hibiko is the wrong app and there are better ones. It's also not a mental-health product: it doesn't diagnose or treat anything, and it's not a substitute for a therapist. And if you're outside Turkey, check the store listing for your region before subscribing, because the phone calls are the reason to be here and coverage varies.
next to the others| app | the shape of it | pick it over Hibiko when… |
|---|---|---|
| Finch | Self-care pet with a wide surface of daily tasks and a gentle gamified loop. | You want breadth — mood check-ins, journaling, many small tasks — rather than one hard commitment. |
| Fabulous | Coached routine builder with structured programs and heavy onboarding. | You want a whole morning routine designed for you, not a single habit. |
| Habitica | RPG habit tracker with parties, quests and gear. | Game mechanics genuinely motivate you and you like managing systems. |
| Streaks | Clean, fast multi-habit tracker built around the streak. | You already do the habit and just want a tidy record of it. |
| Hibiko | One habit, 66 days, a companion that phones you unpredictably and remembers what you promised. | Your actual problem is that you ignore reminders and nobody is holding you to anything. |
Descriptions of other apps reflect their positioning as of 2026 and are meant as an honest routing guide, not a knock — several of them are excellent at what they do.
the money partThe app is free to download. Premium unlocks the calls — the daily reminder call, the unannounced weekly check-ins, and the full 66-day journey. It's an annual subscription with a 7-day free trial, cancellable any time, and nothing is charged during the trial.
It's sold only as an in-app purchase through the App Store and Google Play — there is no web checkout, so don't look for one here. Prices are set per store and per country, so the listing for your region is the authoritative one. The reason there's a paywall at all is unglamorous: placing real phone calls costs real money per minute.
the nameFrom the Japanese hibi (日々) — "every day." Big changes grow out of small seeds planted every day, which is both the name and the entire mechanic.
the usual questionsYes. Not an in-app notification or a chat thread — your phone actually rings. In Turkey that's an ordinary phone call to your mobile number. Your AI companion has a short conversation, anywhere from 30 seconds to a couple of minutes: how's it going, what are you doing today?
Because tracking five habits at once is the most common way to do none of them. While a journey is running you cannot add a second habit. You finish the 66 days, you harvest, and then you start again with a new one.
Hibiko was designed for scattered minds. No to-do lists, no points, no charts, no streak counter, no shaming — all deliberately left out. The screen shows one small step for today. Hibiko is not a medical product; it does not diagnose or treat anything.
The daily reminder call arrives within a time window you choose. On top of that, a few times a week, unannounced check-in calls arrive when you are not expecting them. Not knowing when it will ring is the mechanism — it keeps the habit parked in the back of your mind.
Nothing bad. Hibiko tries once more, then lets it go. It will not guilt you about a missed call, and your companion is not harmed by it.
No. Hibiko never dies, never sulks and never blames you. That is a deliberate design decision: guilt-based apps work for a week and get deleted in a month. On a day you skip, no seed gets planted. That is all.
The app is free to download. The calls and the full 66-day journey are unlocked by a Premium subscription — an in-app purchase, billed annually, with a 7-day free trial and cancel any time. It is sold only through the App Store and Google Play; there is no web checkout. Prices vary by country and store, so your store listing is the authoritative one.
Outbound phone calls currently work best in Turkey, where Hibiko places real calls to your mobile number. Coverage elsewhere varies — check the store listing for your region before subscribing if the calls are the reason you are installing.
Focus mode is optional. Turn it on and the apps you picked stay shut until you have done your habit. It runs through Screen Time (Family Controls) on iOS and an accessibility service on Android.
You harvest your field and the journey is saved to your history. Then you can start a fresh 66 days with a new habit. Your companion, its cosmetics and everything it collected stay with you.
Because the product itself is a phone call. Your number is both how you sign in and how Hibiko reaches you. Sign-in uses a one-time code over SMS — there is no password.
Finch is a self-care pet app with a broad surface of daily tasks and a gentle gamified loop. Hibiko narrows all the way down to one habit and adds a real, unpredictable phone call as the accountability layer. If you want a wide self-care surface, Finch fits better. If your actual problem is that you swipe reminders away, Hibiko is built for exactly that failure.
