Isabella · Today's insight
"Your on/off periods are down to 1 this week — your best in over a month. Your medication has been on time every day this week, and your walking speed has improved to 1.02 m/s. The pattern is clear: consistent timing is making a real difference. Your neurologist will want to see this at your next appointment."
New to Ziva?
Ziva Health is an AI-powered health companion for managing chronic conditions. Isabella is Ziva's AI coach - she tracks your medication timing, reads your wearable gait data, logs your on/off tags, and builds a daily picture that you and your neurologist can actually use.
How Ziva works for Parkinson's
Three steps to understanding what's driving your day.
Understanding Parkinson's
It's not just tremor.
It's a daily management challenge.
Parkinson's disease is a progressive neurological condition affecting movement, balance, sleep, mood, and cognition. Symptoms vary enormously from person to person and day to day - largely driven by how well medication levels are maintained throughout the day. Understanding what's driving your symptoms gives you and your neurologist something to act on.
💊
Medication timing drives on/off periods
Parkinson's medications have a narrow therapeutic window. When levels dip - from a late or missed dose - on periods become off periods: stiffness, freezing, difficulty moving. Consistent timing is the most direct lever you have.
🚶
Gait changes are early warning signals
Declining walking speed, reduced step length, and increasing asymmetry are objective signs of motor progression - detectable by Apple Watch before they become clinically obvious. Tracking them over months tells a story your neurologist can act on.
😴
Sleep and autonomic function
REM sleep behaviour disorder is common in Parkinson's. HRV decline reflects autonomic dysfunction - a core non-motor feature. Both are tracked automatically by your wearable and visible to your neurologist.
🧠
Non-motor symptoms matter too
Depression, anxiety, brain fog, and fatigue affect most people with Parkinson's and are often under-reported at appointments. Isabella makes it easy to tag these when they happen - so your neurologist has the full picture.
What you can tag in Ziva
🔄
On/off periods
Tag when you switch from feeling controlled (on) to stiff or frozen (off). Timestamped and correlated with your last dose.
〰️
Dyskinesia
Involuntary movements from medication peak levels - log when and how long they last.
🧊
Freezing episodes
Sudden inability to move, especially when starting to walk or turning. Tag it - frequency matters for your neurologist.
⚠️
Falls
Log falls immediately - with time and medication context automatically captured. Creates a documented record for your care team.
😔
Mood, fatigue & brain fog
Non-motor symptoms are often dismissed because they're not reported. Tag them - Isabella tracks patterns over weeks.
Carers can help
If motor difficulties make phone interaction hard, a family member or carer can log medication doses and tags on your behalf. Set up carer access during onboarding - everything goes to the same shared record your neurologist sees.
Medication timing
Consistent timing is the most
controllable part of your day.
Parkinson's medications work within a narrow window. When a dose is late, medication levels dip - and on periods can quickly become off periods. Isabella reminds you at every scheduled time, logs each dose with a timestamp, and shows you - and your neurologist - how adherence is correlating with your on/off period frequency over time.
✓Reminders at every scheduled dose time — set by your neurologist from the portal or by you in the app
✓Every dose timestamped — late doses flagged and visible to you and your care team
✓On/off period correlation — Isabella automatically links late doses with on/off episodes that followed
✓30-day adherence percentage in your monthly report — visible to your neurologist before every appointment

Isabella · Gait insight
"Your walking speed has improved from 0.82 to 1.02 m/s over 4 months — a 24% improvement that directly tracks your medication adherence improving from 58% to 96%. Walking speed above 1.0 m/s is a meaningful functional milestone. Your neurologist will want to see this trend. Keep the same routine."
Gait tracking
Your Apple Watch measures
how you walk, every day.
Walking speed, step length, and walking asymmetry stream automatically from Apple Watch each day - no logging, no effort. Isabella tracks these gait metrics over months, correlates them with your medication adherence, and includes the trend in your monthly report. Your neurologist gets objective gait data between clinical exams.
✓Walking speed — daily average from Apple Watch, trended over weeks and months
✓Step length — shortening step length is an early indicator of motor progression
✓Walking asymmetry — side-to-side difference in steps, correlating with lateralised symptoms
✓Gait trend in your monthly report — 4-month trend with medication adherence overlay for your neurologist
For your care team
Your neurologist sees the same data.
Objective. Before every visit.
When your neurologist is on Ziva, they see your medication adherence, on/off period frequency, gait trend, and fall log - before every appointment. No more describing the last 3 months from memory.

Questions
Common questions
No - Ziva works without a wearable. Medication adherence tracking, symptom tags, and Isabella's coaching are available from the app alone. Apple Watch adds walking speed, step length, and asymmetry data automatically - which makes the gait picture available to your neurologist. HRV and sleep data are also available from Oura Ring, Garmin, and Fitbit. The most impactful feature - medication timing adherence - requires no wearable at all.
Yes. Ziva supports carer access - a family member or care partner can log medication doses, tag on/off periods, log falls, and complete wellness check-ins on your behalf. This is important for people with motor difficulties who find phone interaction challenging. Everything goes to the same shared record your neurologist sees. Carer access is set up during onboarding.
Ziva's medication tracking is a timing and adherence log - your neurologist sets your schedule from the portal, and Isabella sends reminders at each scheduled time. You (or your carer) confirm each dose. Each confirmation is timestamped and compared to the scheduled time. Late doses are flagged. The 30-day adherence percentage and late dose pattern are visible to your neurologist in the monthly report - and correlated with your on/off period tags from the same period. Ziva does not dispense or manage medication - it tracks timing and adherence.
Apple Watch tracks walking speed, walking step length, walking asymmetry (difference between left and right steps), double support time, and step count - all via HealthKit, automatically, without any patient interaction. These metrics are available from Apple Watch Series 4 and later, paired with an iPhone running iOS 14 or later. Walking speed below 1.0 m/s is a recognised marker of motor function decline. Isabella tracks these metrics daily and shows 4-month trends to your neurologist.
Ziva's app is designed with accessibility in mind - large tap targets, simple interactions, and voice input support. For patients with significant fine motor difficulties, carer access means a family member can handle logging entirely. The wearable gait data and medication reminders require minimal interaction once set up. We recommend discussing with your care team during onboarding to configure the right setup for your level of motor function.
