PACECRAFT™ FEATURES
Pace at your own pace.
In development. Beta August 2026.
It runs the protocol, so you don’t have to.
POTS exercise programs come as printed schedules. Eight months of them. Count the weeks, watch your effort, remember what you managed on Tuesday, work out whether a bad fortnight means starting the month again.
Which asks for planning, memory and stamina — the things POTS takes away. The people these programs are written for are the least equipped to run them.
Pacecraft does that part. It keeps the time, tracks what you did, applies the protocol’s own rules about when to repeat a week, and produces something you can hand to a clinician.
The protocols are the clinics’ work, unchanged. Everything around them is what’s new.
THREE published programs, encoded meticulously and with care
CHOP AADP Recumbent
Eight months, 31 weeks. Starts at two minutes lying down. Recumbent or seated for the first five months, then a transition to upright.
CHOP Modified Dallas
Eight months. The Levine-derived protocol as adapted by Children’s Hospital of Philadelphia. It also moves from horizontal to upright.
Utah ADaPT
Published in 2024 by physical therapists and neurologists at the University of Utah, ADaPT was designed as an answer to a specific criticism: that fixed protocols ask more than some people can sustain, and lose them. It adapts to the person instead.
The CHOP AADP Recumbent and CHOP Modified Dallas programs use fixed eight-month calendars — around 31 to 34 weeks if no week is ever repeated. Utah ADaPT works differently: it does not have a set calendar, and progression adapts to the individual’s function and readiness rather than the date. For every program, sessions can repeat when needed, and the app treats that as ordinary rather than as falling behind.
Built for someone who feels unwell
A timer that doesn’t lose count
Keeps time correctly when the screen sleeps, a call comes in, or you put the phone down.
Everything happens three ways at once
Phase changes are spoken, shown, and felt. Nothing important only happens on screen.
Effort, not just heart rate
Effort is the primary target. Heart rate is optional, and it never decides whether a session counted.
Stopping is one tap
“I need to stop” is always in the same place. No confirmation dialogue.
Missing sessions is expected
Stopping never counts as a failure of yours. It’s recorded as what it was, with an optional symptom log and an offer to lie down with your feet up.
Repeating a week isn’t going backwards. It’s the same week, and your body gets another run at it. The rules about when that happens belong to the protocol.
No streaks. No badges. Nothing to break. There is no number that gets worse when you have a bad fortnight.
Something to take with you
One page, made on your phone, that you decide who sees.
Which program, where you’ve reached, sessions completed and missed, every time the program repeated or stepped back and what caused it, your symptom score, and anything you saved to bring up.
It names the questionnaires it used, so a clinician can judge them rather than take an app’s word for it. Pacecraft never sends it anywhere and keeps no copy.
Post-exertional malaise changes the answer
If your symptoms get worse hours to a day or two after activity rather than during it, adding exercise on your own is how crashes happen.
Pacecraft screens for that and offers a different track instead: working out where your limits are, rather than building up. What you spend energy on, what came before a crash, and the patterns you can’t see day to day.
It isn’t a smaller version of the exercise program. It’s a different job, and for PEM it’s usually the one that comes first. If a clinician has prescribed you an exercise program despite the PEM, the app can run that too — starting at the lowest point, with weeks repeating whenever a flare gets in the way.
It stays on your phone
No account needed. No name, no email. Nothing to sign up for.
Your health data is encrypted on the device. No analytics service ever receives it. There are no adverts.
The clinician report is made on your phone and shared by you. Pacecraft never transmits it. Everything can be exported or deleted in one action.
Not HIPAA — that covers healthcare providers and insurers, not apps. Pacecraft is built so there’s very little to breach in the first place.
One person, who has this
Diana has POTS and several other forms of dysautonomia, severely.
She built Pacecraft because the protocols she was given were genuinely hard to follow, and hardest for exactly the people they’re written for.
Which is why there are no streaks, why nothing scolds you, and why stopping is one tap. Those aren’t design decisions taken from a distance.
What Pacecraft doesn’t do
It doesn’t treat POTS. It runs a protocol. Whether that protocol helps you is between you and your clinician.
It isn’t a medical device and isn’t FDA-cleared. It doesn’t diagnose anything. The questions at the start decide which program fits, and nothing else.
There’s no evidence for Pacecraft itself. The protocols have published research behind them. The app is new and nobody has used it yet.
If you have chest pain on exertion, have fainted and been injured, have a diagnosed heart condition, are pregnant, or have new symptoms nobody has looked at — the app will stop and give you something to take to an appointment instead. That isn’t negotiable and you can’t click past it.
Beta in August 2026
An early version, so it won’t have everything and it will have rough edges.
