Steady: a fasting app for the one hour that decides your fast.
Fasting is one decision a day. Most fasting apps turn it into forty.
A streak to protect. Badges to earn. Water, weight and steps to log. A dozen notifications before lunch. None of it helps at the hour you want to eat. All of it is one more thing to fall behind on.
So I built Steady the other way around. It is a timer, one check-in at the hour that matters, and a record that tells the truth. That is the whole app.
Hungry is easy. The stack is what beats you.
Hunger on its own is manageable. What ends most fasts is tired, hungry and low, all at once. That stack tends to land around the same hour of a fast, and it lifts again not long after. A timer does not notice any of that.
Steady learns when that hour hits you. It checks in just before it. Then, two hours later, it shows you from your own record that the feeling passed.
One check-in, not a dozen pings
Every notification Steady can send fits on one screen. There are four switches:
- A reminder when your window opens.
- A note when you cross a stage.
- A mood nudge that stays off unless you turn it on.
- The one that matters: a check-in half an hour before the hour you said usually decides it.
All of it is scheduled on your phone. No server sends them.
The check-in is two taps. And it will tell you to stop.
You pick a mood and log it. You can skip it. Log a low one mid-fast and Steady offers three minutes of slow breathing, or a small puzzle. Both work offline. Then it asks again two hours later, so your record has something to compare against.
Tap anything physical, like shaky, dizzy or heart racing, and Steady tells you to eat, whatever the hour. It is not trying to get you to 20 hours. It is trying to get you through the hour you usually quit, and to say plainly when you should stop.
A coach that keeps it short
There is a coach for the moment you want to quit. It builds a plan from how your days actually go: when they fall apart, what wanting to quit feels like, and where past fasts broke. It knows your record. It will remind you that you have held past this hour before. It offers a timed delay rather than a lecture. And it does not message you to keep you in the app.
Two numbers. Neither of them is your weight.
Your record shows how many fasts you finished, and your longest. Both can only go up. There is no streak to break and no badge for hitting ten.
Underneath sits the one number worth having: how often you felt better a little later after a low check-in. It is counted honestly, with the fasts you ended early held against it. It is there to take pressure off the hard hour, not to add to it.
Honest about what fasting does
As the window runs, your body shifts from sugar to fat for fuel. That is the whole mechanism. Steady names the stages plainly:
- 12 hours, the switch. Reserves run low, and fat starts doing more of the work.
- 14 hours, running on fat. Hunger tends to come in waves.
- 16 hours, the good part. The stretch most people come for.
- 18 hours, cruising. For many people, hunger settles from here.
- 20 hours, full burn. The far end of what Steady asks of anyone.
Autophagy and true nutritional ketosis need roughly 24 hours or more. Steady tops out at 20, so it does not reach them. You will not see an autophagy badge at 16 hours, because it does not happen at 16 hours.
No account. Your data stays on your phone.
There is no sign-in, no analytics and no advertising. Everything Steady knows about you lives on your iPhone. Delete the app and it is gone.
When you talk to the coach, the context for that one reply goes to a server that stores nothing. Your phone keeps the conversation. Steady asks about medications so the coach can be careful, but the server only ever gets a yes-or-no risk flag. Which medication stays on your phone.
Try it
Steady is free on iPhone while it is in beta. Fasting windows run from 12 to 20 hours. Tell me what breaks.
