An iOS app for intentional discipline. Challenges, askesis, calendar events. No account. No recurring charges. Just you and your word.
Practices · Discipline · Intention
Vow is built around a single idea: when you say you'll do something for thirty days, the app is there for those thirty days. No streaks to brag about. No badges. No noise. Just the window, the breath, the day.
You take a vow — a habit challenge, an askesis with a price of intention, or a calendar event like Ramadan, Lent, or Vesak. Each day, you mark it within a window. At the end, you receive a certificate. That's the whole loop.
No marketing copy. These are lines the app uses with every paying user.
You're not tracking habits.
You're keeping your word.

A simple daily habit — read fifteen minutes, walk eight thousand steps, no alcohol. Three difficulty tiers. Free to take, just a streak you can break and rebuild.
A deeper commitment carrying a price of intention — one, twenty-five, forty-five, or one hundred dollars, paid once when you begin. It is not a deposit, not a bet, and nothing is held at risk: the payment is what makes the word weigh something. Complete the period and you receive a certificate. Miss a day and the askesis simply ends.
A practice anchored to a calendar moment — Ramadan, Lent, Vesak, Solstice, Advent, Dry January — or to a defined social discipline like a complaint fast. Fixed dates. Same price of intention. Same strict window.
A year-long container rather than a single vow. You name one intention, choose the sphere it belongs to — work, body, relationships, growth, environment — and set up to six checkpoints across the year, each with its own notes and subtasks. Inside it you can run up to three embedded practices of thirty, forty-five or sixty-six days. Up to five reference photographs stay on your device and never leave it. The year closes at nine in the evening on the thirty-first of December with a summary of what actually happened and a certificate.
Priced by the quarter you enter, because a year joined in October is not a year joined in January. Paid once. Nothing renews.
Every day has a check-in window. You can mark inside it. Outside it, the day doesn't count. The diary does not replace the check-in.
The app shows today's countdown. You can enter Askesis mode anytime.
Or you don't. First and last, you are honest with yourself. The app does not verify on your behalf — it holds the window and counts the days.
One tap, one haptic, one day added to the dot grid. A gold ring at every seventh day. No screenshots, no proof — the contract is with yourself.
For a free challenge — broken streak, no consequence beyond honesty. For an askesis — the day is missed and the askesis is not completed. No retroactive marks. No exceptions.
Events have their own windows — Ramadan after iftar, Vesak at dawn, Lent in the morning. Each event states its window before you commit.
No feed. Notifications only when they matter: window opens, window closing. No reminders for the sake of it. Just the practice, the window, and today.
One screen. One discipline. Everything else stays outside.
The check-in window. Breath cadence. The Mark button. That's it.
One askesis. One challenge. One planned event. No more.
Cultural anchors. Fixed dates. Same rules for everyone in the room.
Every challenge, askesis, event, and practice is written by one hand. No automatic user-generated content. The catalog is the product. There is a "Suggest an event" form inside the app — we read every suggestion. Accepted ideas join the catalog no more than once per quarter, at the team's discretion.

Each event in Vow has its own emblem, color palette, breathing practice, marking window, and final scene. The visual respects the tradition — no stock religious imagery, no clichés.
30 days. Marking after iftar.
47 days. Morning window. Phased progression.
7 days of non-attachment. Dawn window.
25 days, 4 weeks. Evening candle.
Open the app and start. We don't ask for your email, phone, or name. Your data lives on your device, not on our server. On entry we ask only for age — this opens the right catalog for you: under 13, the app gently declines; 13–17, a free version without askesis and payments; 18+, the full catalog.
Vow is for people tired of paying every month. Pay for a vow when you take it. That's it. Nothing renews, and there is nothing to cancel afterward.
The app does not watch you in any form. Not your data, not whether you actually keep the conditions of your askesis in real life. No Mixpanel, Amplitude, Firebase Analytics or any other SDKs. The app trusts you — because it trusts your honesty with yourself.
No badges, no leaderboards, no competition with others. A streak belongs to you, not to an audience. A vow is a vow, not a game. We respect the seriousness of the practice.
Advertising — never. We do not sell your attention to a third party and we do not insert banners. Partnership events are possible: a joint askesis with a brand or cultural institution, with its own visual world and the same rules of window and completion. That is part of the catalog, not an ad.
The closed beta is over and Vow is in final preparation for the App Store. Leave your email and we will write exactly once — on the day it goes live. No newsletter, no drip campaign, no second message.
Get launch noticeWhen you start an askesis, you choose an amount: one, twenty-five, forty-five, or one hundred dollars, paid once at the start. It is not a deposit and not a wager — nothing is held at risk, nothing is won, and nothing is taken from you if you stop. It is simply what a serious vow costs, and you choose the amount so the weight matches the word.
Challenges have a marking window each day. If you miss it, you can either skip the day (free in the easy tier, paid in higher tiers) or end the challenge early. Ascets are stricter — missing a day ends the askesis without success. This is the design.
Yes. Paired ascets let two people commit to the same vow together. You share a code, both walk the same days, and exchange a small haptic ping when you're each present. No shared score, no chat — just synchronicity.
Vow has a separate branch for ages 13–17 with simplified, free habit challenges and event versions. No askesis, no payments of any kind, no paid skips. Anyone under 13 receives a gentle decline at sign-in.
Not in 2026. The product is built specifically for iOS — Live Activities, Widgets, Dynamic Island. Android is a possible future, not a near plan.
