An iPhone 11 or newer running iOS 26 or later, and an Apple Watch Series 4 or newer running watchOS 10 or later. The Watch is essential - it is where tremor and dyskinesia are sensed. Kampa works with older Watches like the Series 5 and first-generation SE.
No - this is expected. Tremor sensing needs a few days of regular Watch wear before patterns appear. Wear your Watch through your normal days, and Kampa will start showing data as it accumulates. If you see nothing after 3-4 days of wear, check that Kampa has Motion and Health permissions in Settings.
No, but open it every few days. Your Watch stores about a week of tremor data and hands it to your iPhone when the app opens. If the app stays closed longer than that, the oldest days can be lost. Kampa will remind you if it has not heard from your Watch in a while - that reminder is the one notification we will always send, because your data matters. We are working toward fully automatic background sync.
Health access (to read sleep, exercise, heart data, medications, and to save what you log), Motion access on the Watch (tremor and dyskinesia sensing), and optionally notifications (used only for the handful of things worth interrupting you for - like the Watch losing sync). Kampa asks for nothing it does not use.
In the Apple Health app, which is the system of record for medications on iPhone. Log a dose there (or via Siri with Apple's own medication features) and Kampa reads it automatically and places it on your timeline. Kampa deliberately does not keep a separate medication list - one list, no double entry.
It is a None-to-Strong severity estimate produced automatically from your Apple Watch. The labels echo the severity language clinicians use, but the number is a passive estimate from wrist sensing - not a doctor's exam, and not a clinical score. Use it to compare your own days against each other, not to compare yourself against anyone else.
Each point on the line is your typical tremor level over a short window - about ten minutes - so the chart shows how your tremor actually rises and falls through the day rather than one flattened number. When you touch the line, the callout reads that same window, so the number and the curve always agree. The window is kept short on purpose: tremor can change quickly, and a longer average would smooth a real ten-minute surge down below what you felt.
The figure beside "Tremor" at the top of Review is a plain average across the entire day, calm hours included. Tremor is often either near zero or clearly elevated, with little time in between - so a whole-day average settles at a level you rarely actually sit at, below your real peaks. Read the chart for the shape of your day; treat the daily average only as a rough way to compare one day against the next.
Different apps measure different things. Kampa's chart shows tremor intensity - how strong the tremor was, through the day. Some other apps report duration - how many minutes of tremor occurred. Both are legitimate lenses; a day can have long mild tremor or brief strong tremor. Neither number is wrong; they answer different questions.
Dyskinesia refers to involuntary movements that can occur as a side effect of levodopa medication, usually at peak dose. Not everyone experiences it - if you don't, a flat line is the correct reading, not a broken feature. Wrist sensing can also register some ordinary movement as possible dyskinesia, so Kampa is deliberately conservative about what it shows.
Because pharmacologically they often are. Tremor tends to peak before a dose (medication worn off) and dyskinesia at peak dose. Seeing them rise and fall in opposite rhythm around your doses is the levodopa cycle made visible - many people find this one chart explains their day better than anything else.
On today's Review, Kampa projects the likely shape of your day - your probable on and wearing-off windows - from the doses you've logged and how each of your medications has tended to act for you, learned from your own history rather than a textbook drug curve. It is a heads-up for planning, not a dosing instruction. As always, decisions about medication are for you and your neurologist.
Observations describe today: "Tremor eased 68% in the hour after your 8 AM dose." They are honest descriptions of what co-occurred, not proof of cause. Insights are patterns that hold up across many days and pass statistical checks before you ever see them. Observations are the daily read; Insights are the accumulated evidence.
Emerging, moderate, and strong reflect how much evidence supports a pattern - how many days, how large the effect, and how consistently it repeats. Kampa shows the basis plainly ("based on 23 days"). If a pattern stops holding, its card is downgraded or retired. We would rather show you nothing than something that is not real.
Because Kampa applies real statistical standards before claiming anything, and honest standards mean fewer, better cards. Some things genuinely have no effect on your symptoms - learning that is valuable too. Cards appear when evidence clears the bar and retire when it no longer does; the screen reflects the current state of evidence, never a highlight reel.
No. Never. Kampa may surface an observation worth discussing - for example, that your afternoon doses seem to act more slowly than your morning ones - and help you prepare a summary for your neurologist. What to do about it is a decision for you and your doctor.
On your iPhone and in your own private iCloud. Kampa has no servers. We cannot see your data - not because of a policy, but because of how the app is built. Nothing is sold, shared, or used for research without your explicit consent.
No. Optional AI-powered features (like plain-language explanations) send only derived summary statistics - never your raw health data, never your identity - and only if you opt in. Everything else runs entirely on your device.
Yes, always. Kampa exports your data as CSV files you can keep, inspect, or share. It is your data; export is free and always will be.
It stays in your iCloud and your Apple Health store, under your control. Deleting the app removes Kampa's copies; your Health data remains yours in Apple Health.

The simplest way is inside the app: tap + on the Review screen, then speak. Say "5 almonds with tea," "bloated after lunch," or "ten minutes of breathing" and Kampa sorts each into the right place - food, a gut symptom, or a mindfulness session. It reads back what it understood so you can confirm before anything is saved. You can also start food and mindfulness logs hands-free with Siri ("log a 20 minute meditation"). It was designed for days when typing is hard.
Yes. Tap + on the Review screen and describe it in plain words ("bloated after lunch," "nausea this morning"). Kampa saves it to Apple Health and marks it on your timeline, so slow-digestion days can be seen alongside how your doses landed.
Apple allows apps to read medication doses from Apple Health but not to write them. Saying "log my meds" opens Apple Health's own medication screen instead. This is an Apple platform rule, and it exists for a good reason - one trusted list of record for something as important as medication.
No. Kampa works fully without one. If you choose to wear an over-the-counter continuous glucose sensor (such as Abbott Lingo or Dexcom Stelo - no prescription needed), Kampa can display your glucose curve time-aligned under your tremor chart, with doses and meals marked across both.
Levodopa is absorbed and reaches the brain through transport systems that food - especially protein and large meals - can compete with. Your glucose curve is an objective record of your body's meal response, which can help make sense of days when a dose seemed slow or weak. Kampa treats this as an area to observe honestly, not a promise.
Enable Apple Health sharing inside your sensor's own app (for example Lingo). Kampa reads glucose from Apple Health automatically - no separate pairing.
Nothing right now - Kampa is free to use. Sensing, charts, daily observations, logging, and data export are all included.
Kampa is built by Bhav Bhasin, a product builder who has spent 25+ years on large-scale technology and now builds independently, working closely with the Parkinson's community. Kampa began as an attempt to answer questions that existing tools would not: not "what happened," but "what actually affects me?"
Kampa (कम्प) is Sanskrit for "tremor," from Kampavata - the term ancient Ayurvedic medicine used for what modern medicine calls Parkinson's disease. We chose a name that faces the condition honestly.
Parts of it. Kampa's lifestyle logging and correlation tools apply broadly, but the Watch's tremor sensing is tuned by Apple for Parkinson's resting tremor, and some features (like dose-response analysis) are specific to Parkinson's medication. We have not yet validated Kampa for essential tremor, and we won't claim it works until we have.
No. Kampa is a personal wellness and symptom-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional about any medical condition.
