Parky for Parkinson's
Your Parkinson's Companion
Free · In‑App Purchases
7-day free trial now available. FDA cleared in the US, EU MDR CE mark certified in Europe. Passive 24/7 Parkinson's motor symptom tracking via Apple Watch.
Parky is the only FDA-cleared and EU CE-marked Parkinson's tracker built for Apple Watch — giving you and your care team objective, automatic data every day.
Most Parkinson's apps rely on self-reporting alone. Parky combines automatic Apple Watch monitoring with manual symptom logging — giving you and your doctor a complete picture of your day.
WHAT PARKY TRACKS AUTOMATICALLY
— Tremor severity and patterns
— Dyskinesia episodes
— Step count and activity
— Medication timing and intake
SELF-REPORTED LOGGING
— Motor and non-motor symptoms
— Mood and sleep
— How you feel throughout the day
WHAT YOU GET
— Visual trend reports for your neurologist
— Medication reminders integrated into your symptom timeline
— Freezing of gait cueing to help you keep moving
— HealthKit sync for a complete health picture
— Clinically validated data — not estimates
BUILT FOR YOUR CARE TEAM
Parky is prescribed by neurologists and movement disorder specialists. Your doctor gets structured, timestamped reports that replace guesswork with real data — leading to more personalized treatment.
FDA-cleared. EU CE-marked. Clinically validated.
Download Parky and bring objective data to your next neurology appointment.

- Use Statement
- INDICATIONS FOR USE STATEMENT The Parky App is intended to quantify kinematics of movement disorder symptoms including tremor and dyskinesia, in adults (45 years of age or older) with mild to moderate Parkinson's disease.
- Safety Information
- LIMITATIONS
1) Parky operates under the following constraints:
-Parky only operates on Apple Watch and iPhone using the MM4PD algorithm
developed by Apple.
- Parky does not operate on unsupported devices.
- Parky is advised to be used for idiopathic Parkinson’s Disease, and not to be used on
other Parkinsonian syndromes such as progressive supranuclear palsy (PSP),
multiple system atrophy (MSA), Lewy, and corticobasal degeneration (CBD)
- The user should wear the Apple Watch on the most affected arm.
- Dyskinetic symptom tracking should be considered only for users with chorea on the
affected arm, either self-reported or diagnosed by a healthcare provider.
- Parky explicitly tracks resting tremor; it does not track action tremor or postural
tremor, and it may not track finger tremor.
- Parky does not explicitly track dystonia or bradykinesia.
- The results may include false positives and false negatives. The user’s activity, watch
band fit, and concomitant conditions (such as restless legs syndrome and nonParkinsonian tremor) can affect the quality of the results.
- Parky only explicitly measures symptoms from the wrist while wearing the Apple
Watch. However, Apple Watch may sense symptoms transmitted through theody
from other affected body parts, possibly resulting in misleading or false metrics
2) Parky cannot collect data when Apple Watch is turned off and cannot transmit data
when iPhone is turned off.
3) Without adequate recording durations, Parky will not be able to generate symptom
reports. The reports are generated utilizing the following methodology
- Intervals of fifteen minutes, covering the entire duration of the recording, are
organized according to the user's local time.
- Intervals with less than 50% of the required data are excluded.
- The weekly and monthly reports display the mean tremor and dyskinesia symptom
durations from all days with data.
- In the weekly and monthly reports, only the intervals with data collected from at least
five days or representing over 20% of the total period are displayed.
4) Medication schedules are subject to the correctness of data entered by the user. If the
user has difficulties in using the app, it is strongly advised to provide support in-clinic
settings.
5) The accuracy of medication adherence information relies on the user's prompt and
accurate response to medication reminder notifications. Failure to respond or providing
inaccurate interactions may lead to incorrect medication adherence outputs. To mitigate
this risk, healthcare providers are strongly encouraged to emphasize the crucial
importance of accurate reminder responses to users.
6) The step information relies on the user's consistent use of both Apple Watch and
iPhone. Parky cannot collect step data if the user is not utilizing either of these devices.
7) If users would like to stop using Parky, they can cancel their prescription. Upon
prescription cancellation, the user is considered as a dropout, and the prescription is
immediately switched to an invalid state. Users maintain access to the app to review
their existing information and previous reports. However, post-cancellation, the app will
not generate new reports. Additionally, the prescribing healthcare provider loses access
to the user's Parky reports. A new prescription will be required for the user to restart
using Parky.
8) If users would like to stop using Parky permanently, they can permanently delete their
account. Upon account deletion, the user is considered as a dropout, and the health and
personal data of the user will permanently be removed. Both the user and healthcare
provider will lose access to the user's Parky reports.
1) The use of Parky and Apple Watch does not affect users with Deep Brain Stimulation
(DBS) implants.
2) Apple Watch is water-resistant but not waterproof. It can be worn and used during
exercise (exposure to sweat is OK), in the rain and while washing hands.
3) Please refer to the original manufacturer document regarding the user manual and
guides for Apple Watch hardware user manual: https://help.apple.com/pdf/watch/8/en_US/apple-watch-user-guide-watchos8.pdf
4) Guide for Apple Watch: https://support.apple.com/en-us/HT204665
5) Apple Watch conforms to the following EMC and Electrical Standards: Electrical safety
was assessed according to IEC 62368-1 (2014), “Audio/video, information and
communication technology equipment – Part 1: Safety requirements.” Apple Watch
conforms to EU standards EN 301 489-1 (V2.2.20), EN 301 489-3 (V2.1.1), EN 301
489-17 (V3.2.0), and EN 301 489-52 (V1.1.0). - Instructions for Use
