Private by design
PHI stays with the site. Sponsors and CRAs see only blinded, coded data. HIPAA, GDPR, 21 CFR Part 11 and ICH-GCP built in from day one.
- • End-to-end encryption in transit and at rest
- • Biometric app lock and session timeouts
- • Full audit trail on every tap
Common questions
Is my data private?+
Yes. All personal identifiers stay inside your site's ProCTTH vault. Sponsors, CROs and CRAs see fully blinded data.
Do I need internet all the time?+
No. Forms, diaries and consent work offline and sync automatically when you're back online.
Can I use my own smartwatch?+
If it's Apple, Fitbit, Garmin, Oura, Withings, Omron, Dexcom or most major brands — yes. Full list in-app.
What happens with ProCoins?+
Redeem them for gift cards, travel reimbursements or charity donations, per your site's policy.
From your wrist to the visit form, automatically.
Pair the devices you already own. Buzzby pulls vitals straight into your study forms — no manual entry.
Every module, explained.
What the subject actually sees, screen by screen — and what it means for data quality at the site.
eConsent, end to end
The full informed consent document arrives in the app in the subject's chosen language, broken into readable chapters with plain-language summaries, illustrations and short explainer videos for each section.
Why it matters · Sites see fewer re-consents and cleaner Part-11 signature records, because the app enforces version control and blocks signing on superseded documents.
- Chaptered document with comprehension checks
- Ask-a-question thread on any paragraph
- Legally authorised representative co-signing
- Re-consent push when a new version is approved
- Timestamped, geo-stamped signature capture
- Signed PDF stored in the site vault instantly
ePRO, eDiary & visit forms
Scheduled questionnaires, symptom diaries and visit forms appear as a simple task list. Conditional logic hides anything irrelevant, and partially completed forms are saved continuously so nothing is ever lost.
Why it matters · Time-stamped entry windows prevent back-filling, giving sponsors defensible diary compliance data instead of paper reconstructed at the next visit.
- Validated instruments (VAS, NRS, PRO-CTCAE, EQ-5D)
- Entry windows with grace periods per protocol
- Photo, audio and video attachments
- Offline capture with conflict-free sync
- Streak view showing personal compliance
- Auto-flag of out-of-range values to the site
Telemedicine & messaging
Encrypted one-to-one and group calls with the investigator or coordinator run inside the app — no external meeting links, no accounts to create, no PHI leaving the platform.
Why it matters · Remote visits reduce travel burden for the subject and keep the visit record, call log and any captured vitals attached to the same source document.
- In-app video with waiting room and consent to record
- Threaded messaging with read receipts
- Interpreter can be added to any call
- Share screen for imaging or lab reports
- Call metadata written to the audit trail
- Low-bandwidth audio-only fallback
Safety reporting
A persistent report button lets the subject describe an adverse event in a guided flow — severity, onset, ongoing status, concomitant medication — with photos and wearable readings attached automatically.
Why it matters · The site receives a real-time alert with structured data, cutting the gap between event and awareness from days to minutes.
- Guided AE and SAE questionnaires
- Severity and causality prompts in plain language
- Auto-attached vitals from the last 24 hours
- Escalation to the on-call investigator
- Follow-up prompts until the event resolves
- Emergency contact card always one tap away
Reminders & broadcasts
Dose reminders, visit windows, fasting instructions and diary prompts are generated from the protocol schedule, and the site can broadcast urgent messages to a cohort at any time.
Why it matters · Protocol adherence improves measurably because the subject never has to remember the schedule themselves.
- Protocol-driven medication and visit reminders
- Snooze and quiet-hours preferences
- Escalating nudges for missed diary entries
- Cohort-wide emergency broadcast
- SMS and email fallback if push is disabled
- Read confirmation visible to the site
Compensation that feels instant.
Every protocol activity carries a coin value defined during study setup. Coins post to the subject wallet automatically the moment the site verifies the activity — no invoices, no cheques, no "when will I be paid?" phone calls.
Coins post as soon as the coordinator signs off the visit.
Small daily rewards for on-time ePRO and eDiary entries.
Bonus drops at screening, randomisation and study close.
Gift cards, travel reimbursement or charity donation.
