See the pattern in your day with Parkinson's

The diary for people with Parkinson's. Medication, on and off moments, falls and freezes: logged in seconds and ordered for you. So the conversation with your neurologist is about what happened, not about what you can still remember.

Free to use. No ads and no trackers in the app.

The home screen: your next dose, how things are right now, and one tap to log anything.

A week, the way it actually went

Without an overview, you have to recount your weeks from memory in clinic. When did the stiffness come? How long did a dose hold? Was that restlessness new? The answer soon becomes "it varies", and your neurologist can do little with that. With Parki you tap how things are going a few times a day. The app sets that beside your doses, hour by hour and day by day, so you see patterns you would otherwise lose. And you simply take them to your appointment.

  • Insights, the day dial: 24 hours in a circle, showing when things went well, when stiff or restless, and the doses.

    The day dial: 24 hours in one circle

  • Insights, the week: hours of moving smoothly per day, the hours smooth, stiff and restless added up, and each day as a band below.

    Your week: how many hours went well

  • The report for your neurologist appointment: the past weeks on one screen.

    The report for your neurologist

Six months pass between appointments. Your memory doesn't keep up.

In clinic you get ten minutes to summarise half a year. That is exactly when it is hardest to recall when the off periods came, how often you fell, or whether that quarter-past-four dose really worked.

  • Off time disappears from view

    A stiff morning already feels distant by dinner. Yet when the stiffness starts says more about your schedule than almost anything else.

  • Paper gets lost

    The booklet is at home, the notes are spread across three apps, and the rest lives in your head.

  • The people around you are guessing

    Whoever is looking out for you rarely knows how it truly went, and you don't want to file a daily report.

Three steps, half a minute a day

Parki asks very little of you. That is the whole idea.

  1. Record what happens

    One tap for stiff, okay or restless. Large buttons for a fall, a freeze or pain. A dose is confirmed straight from your Lock Screen.

    Something happened?

  2. Parki orders it for you

    Loose moments become hours on and off, a 24-hour day dial, and weekly trends. Every logged moment automatically carries the motor state of that instant.

    At these times

    4× a day

    4. 22:00stays put

    You took the first dose 12 minutes late. The ones after it move along; the bedtime dose stays put.

  3. Take it to your appointment

    One report over the period you choose, in the order a neurologist works through. Bring it on your phone, or with Parki+ share it straight away by email or message.

Everything your day with Parkinson's touches, in one place

Not a separate pill reminder, a separate diary and a third app for exercises. One app that understands how they relate.

Medication that moves with you

Levodopa runs on intervals, not on the clock. Take a dose late and the doses after it move along. Every dose is kept as taken, skipped or taken late.

Medication: today’s doses on a timeline, three already taken and the next one coming up.

Your next dose on your Lock Screen

On iPhone the next dose counts down on your Lock Screen and in the Dynamic Island. Tap Taken without unlocking your phone.

A rhythm when you freeze

Stuck in a doorway? Parki gives you a beat to walk to: as a vibration, a click or a light. You choose the beats per minute.

The rhythm screen: a tempo in beats per minute, as vibration, tick or light.

An emergency card a stranger can read

Your schedule, your neurologist and the warning not to stop your medication suddenly, on one screen. It works offline too.

The emergency card: medication schedule, neurologist and a warning not to stop suddenly.

And also

  • Falls, freezes and pain A few taps record where it happened, what led up to it, and whether you got up unaided. Structured, and therefore countable.
  • A report for your neurologist Check-ins, adherence, falls, freezes, pain and on/off hours over a chosen period. One summary, ready for the appointment.
  • Exercises and self-tests Parkinson's-specific exercises with their level of evidence, plus finger-tapping, spiral and alternating-tap tests that mirror what happens in clinic.
  • Apple Health, read-only Walking speed, step length, sleep and activity come along by themselves. If your Apple Watch detects a fall, Parki offers to log it.
Every feature, part by part
The Who can look screen: switches per person for medication, movement and symptoms.

Let people look along. Exactly as much as you want

Invite your partner, your son or your home-care worker, and switch on per category what they may see. Never all-or-nothing, read-only by default, revocable at any moment.

  • Per category: medication, motor state, symptoms, wellbeing, emergency card
  • Only people you allow can record anything, and their name goes with it
  • Invite by email or shareable link, revoke in a tap

How the care circle works

Your health is yours. On our servers too

Parki is built for data that is nobody else’s business. That is not a setting to switch on. It is in the design.

Read exactly what happens to your data

Encrypted in the database
Every note, your emergency card, and anything you write yourself is stored encrypted. A stolen backup yields unreadable text.
Backups in Europe
Nightly backups with their own password, in EU Central (Amsterdam), kept for three months.
Deleting really deletes
Delete your account and everything goes with it: sessions, tokens, every row. No archive, no shadow copy.
In the app: no ads, no trackers
The app resells nothing and measures nothing with third parties. There is no money to be made from who you are.

What people usually ask first

See all questions

What does Parki cost?

Parki is free to download and free to use: logging, medication with reminders, your insights for the past week, the emergency card and two people in your care circle. If you want to look back further, share the report straight with your neurologist or let more people follow along, there is Parki+: €4.99 a month or €39.99 a year, with a 14-day free trial on the yearly plan. You cancel it in the App Store or Google Play. There are no ads and no data is resold.

Is Parki a medical device?

No, and that is deliberate. Parki makes no diagnosis, gives no treatment advice and interprets no measurement. It records what you report and measure, and makes it clear. Decisions about your treatment belong to you and your neurologist or Parkinson's nurse.

What happens to my data?

Everything you write in your own words and everything that identifies you is encrypted in the database. Backups sit in Europe (Amsterdam) with their own password and rotate out after three months. Delete your account and everything is hard-deleted, no archive remains.

Does Parki work on Android?

Parki is built for iPhone and Android alike. On iPhone you also get the dose on your Lock Screen, the Dynamic Island and Apple Health. On Android everything else works the same; a Health Connect link follows later.

Do I have to fill something in every day?

No. Parki works fine if you only log when something happens. Check-ins take thirty seconds and you can skip them. Parki gives no scores and no verdict on how your day went.

Can my partner or home-care worker look along?

Yes, through the care circle. You invite someone by email or link and switch on per category what they may see: medication, motor state, symptoms, wellbeing or the emergency card. Following along is read-only by default; if you want someone to be able to record for you, you switch that on per person, and their name goes with it. You can stop access at any moment.
