Rated 5.0 on the App Store
You keep your word to everyone. Except yourself.
FlexMax is an accountability app for your daily schedule: it holds you to your word, one block at a time. Little by little, the life you planned gets traded away: to the scroll, to everyone else's priorities, to hours you never noticed passing. FlexMax gets you back into the day while there’s still day left.

We track our steps.

What about the life we want?
Every block you plan is a promise to yourself. FlexMax makes sure each one gets an answer, and helps you keep it, even on the messy days.
One day, start to finish.
Four things happen on every day you use it. Screens show the app's example history, the same two months you can explore read-only if you turn down the trial.

Every block gets an answer.
Every block is a promise you made to yourself. When it ends, FlexMax asks how it went: Excellent, Partly or Rough, with a note if you want one. Done isn't the whole story, so it records how well, not just whether.
Your streak counts days where every block got an answer. Miss something and say so, and it survives. Only silence breaks it.
3:30 PM
Missed it? Keep your word anyway.
Planning slipped at lunch. Mark it missed and FlexMax shows your own last reflection, then finds the time you still have today: 3:30 to 4:15, full length. Nothing overlaps, and you see what moves before you commit.
One miss doesn't get to write off the day. Back on Today, the morning card tells you what your record says about days like this one.
Every Monday and Friday
Over weeks, it learns you.
Theory of You is your own history, written back to you with the evidence behind every line. Findings say what's holding, what's slipping and what's turning around, with the counts: after late nights, 68% of the next day; after on-time nights, 92%. Hypotheses go a step further and propose why, quoting your own dated reflections, offering an alternative explanation, and giving you one concrete adjustment to try. History keeps every past reading, so you can see what changed.
The numbers are calculated first. The AI only puts them into words, and it has to cite your exact notes. Tap Track this to watch a hypothesis play out, or That doesn't fit and it stops saying it. If there isn't enough evidence yet, it says so instead of guessing. How the engine works
Any time you need it
An honest record. Not a perfect one.
Tap the streak and see what you've actually kept: days of accountability, your first two weeks against your latest two, the block that holds the rest of your day together, and how many times you came back after a bad stretch.
This is the evidence for the day someone asks what you've been doing. Including when that someone is you.
Built around the moments a plan dies.
A plan rarely fails at the planning stage. It fails at 2 PM when you don't feel like it, at 11 PM when you're still up, and in the gaps where a thought you never wrote down turns into an hour.
The founder's own numbers.
I built FlexMax for myself first. These come straight from my account, not a study, and not a promise about yours.
- 34% → 83%
- Completion in my first 14 days versus my latest 14: from keeping about 1 in 3 promises to myself to more than 8 in 10.
- 61 days
- In a row with every block answered, including the ones I missed.
- 7 of 7
- Days in the last month my morning slipped and the afternoon still held. It used to go down with it.
No confetti. No badges. No points. No AI chat.
Built for one thing: keeping your word to yourself.
Recover the day. Learn why it slips.
14 days free. Then one plan.
$14.99 a month, or $119 a year Best value: about $9.92 a month
Cheaper habit apps track whether you ticked a box. FlexMax rebuilds the day when it breaks and shows you why it keeps breaking: recovery instead of a red X, patterns instead of completion counts.
Sunsama charges $22 a month to hold your plan. FlexMax holds you to it, for less.
The trial starts through Apple when you choose a plan. Cancel in iPhone Settings before day 14 and you won't be charged. We send one reminder three days before it ends. Theory of You unlocks when the subscription begins.

Is this a planner or a calendar?
It’s a time-block planner with accountability built in. A planner holds your plan. FlexMax holds you to it. You set up your week once and FlexMax handles what happens after the plan: checking in, recovering a broken day, and showing you patterns over time. Events from the calendars on your iPhone, including Google, Outlook and iCloud, can be shown alongside your blocks so you plan around them.
Does FlexMax block apps?
Only if you turn protection on for a block. You choose the apps with Apple's Screen Time picker; FlexMax never learns which ones. During a protected block those apps show a shield. You can leave the distraction, or continue for five minutes, after which the shield returns on its own. Nothing is recorded against your day.
What do I get on day one?
Check-ins, the honesty streak, recovery, the Inbox, the Calendar, block protection and Time2Sleep all work from the first day of the trial. Personal findings and hypotheses in Theory of You unlock when the subscription begins, and they need at least five days of check-ins, so the trial builds the record they read.
What happens to my reflections?
To write a finding or hypothesis, FlexMax sends your recent counts, block names and reflection text to Anthropic's Claude. Your name, email and account ID are never included. App selections for protection never leave your iPhone. Read the privacy policy for storage, analytics and deletion.
Is there an Android or desktop app?
Not yet. FlexMax is iPhone only for now.
