iPhone app
Write the day, seal it, grow your streak.
Checklist apps only take you so far. DisciplineX asks you to close the day: write down how it went, seal it, and let it stand. The streak is built on exactly that.
Free to use · Membership optional · 14 languages
A sealed day can't be reopened
Close the day and it locks. You can't come back later and decide you did that other thing after all. It sounds harsh, but it's the only way a streak means anything — a streak you can edit is just a number.
Each square is a day. The darker it is, the more of your goals you finished.
The daily loop
Everything you need to understand the app, in three steps.
Morning: set your goals
Write goals for the day, or set up repeating ones for chosen weekdays once. Add a timed reminder if you want one.
During the day: tick them off
Check off what you've done and log your workout. Runs and rides from Apple Health show up on their own.
Evening: write and seal
Write how the day went, then seal it. Let the coach review and score it, and watch the streak grow by one.
What's inside
All in one app, with no separate add-on subscriptions.
Daily goals
Goals for a single day or repeating ones, with an optional timed reminder.
Sealing the day
Close the day and it locks. That's the foundation of the streak, and it can't be undone.
Journal
Write how the day went. What you write stays on your own phone.
Long-term goals
The big ones that take months sit apart, without cluttering the daily list.
Workout tracking
Build your program, log sets, compare with last time. Apple Health connects in.
AI coach
Reviews the day you sealed and leaves a short comment and a score. Membership feature.
Leaderboard
See where you stand among other users, based on the coach's scores.
Nearby
Optional. Send workout invites to people near you. Your location is never shown to anyone.
Look and feel
28 color themes, 23 typefaces, 12 card styles. 14 languages, opening in your phone's own.
Worth saying separately
What you write doesn't reach us
Your journal, goals and workout logs live on your phone. There's no copy on our server, which means we can't read them. There's a cost to that and we won't hide it: delete the app and those records are gone.
We show no ads, work with no ad network, and there isn't a single analytics or tracking tool in the app. We don't sell your data.
Stays on your phone
Journal entries · goals · workout logs · theme and language
Kept on the server
Account · profile · messages · scores · location if you turn it on

Frequently asked
Can I unseal a day?
No. Sealing is permanent, deliberately. If it could be undone the streak would mean nothing.
Will my records follow me to a new phone?
Your account, messages, scores and streak will — those live on the server. Your journal, goals and workout logs are kept on the phone, so you'll need iPhone's own backup and transfer for those.
What is the "3 new people a month" limit?
On the free plan you can message or send a workout invite to 3 new people each month. With people you've talked to before it's unlimited; the limit only applies the first time you reach someone new. It exists to keep spam accounts out.
Is my location shown to other people?
No. If you turn on "Nearby", the other person only sees a rounded distance like "1.2 km". Your coordinates never reach any user, and you can leave the feature off entirely.
What does the coach do, and what does it see?
It reads the goals, journal and workout of the day you sealed, then leaves a short review and a score. That request is only sent when you ask for it, and the text you send isn't stored. Details are in the privacy policy.
Is there an Android version?
iPhone only for now. Android is on the plan but we can't give a date.
How do I delete my account?
In the app: Settings → Delete My Account. You don't need to contact anyone; it's immediate and permanent.
Start today, not tomorrow.
The first day you seal becomes day one of the streak.
