Time in one tap
A large coral timer on Today. Persisted before any animation, accurate through background, lock, termination and relaunch — with a Lock Screen Live Activity where supported.
No pause • no silent loss
Epilepsy-first health log for dogs • iPhone
Capture the moment, not the paperwork.
Log4Paw is a calm, on-device seizure log for dogs — one-tap timing that keeps running on the Lock Screen, structured records without the stress, medication reminders and vet-ready reports.
Local-first privacy: your records stay on this iPhone. No account, no cloud service, no analytics. You choose when to export or share. Observation, not diagnosis — Log4Paw records what you saw; your veterinary team interprets it.

Why Log4Paw
Stress-aware, reliable, honest.
During a seizure you need one big, obvious button — not a form. Afterwards you need a short, guided record. Log4Paw is built for one-handed, stressful moments first, and for calm review with your vet second.
Record without stress
A 4-step form with per-step drafts: timing, what you observed, before & after, care & media. Observation chips — never a diagnosis question. Save a basic record or add details.
Observation, not diagnosisShare when you choose
Trends, a date-range report builder and one-tap PDF + CSV sharing for your vet. Full JSON backup with media option. Sharing is the moment data leaves your phone — and it only happens when you tap Share.
You stay in control

Late / missed med
None noticed
Owner-observed intensity only — mild, moderate, severe or not sure. Labelled as your observation, never a clinical grade. Context is never presented as a cause.
Tap Start — saved first
Start time, pet and draft are persisted before the button changes. Double-start is prevented.

Keeps running everywhere
Background, lock, termination, reboot — elapsed is recomputed from the saved start date. Live Activity with Stop where supported.

Tap Stop — event saved first
Exact end time and duration are written before anything else. Then: Add details or Save basic record.

Honest edge cases
Cancelling creates no event. Left running > 24 h shows a warning and requires an explicit stop or cancel.

Fixed-width timer — layout never shifts while counting. VoiceOver announces state, not every second.

Seizure timer
One tap when it matters most.
No navigation, no form, no decisions during the event. The timer is the source of truth — absolute start and end dates — so the duration survives anything iOS does to the app.
- ✓Live Activity, graceful fallback — Lock Screen + Dynamic Island with Stop action where available; the in-app timer never depends on it.
- ✓Large, one-handed control — 144 pt minimum, light haptic on start, success haptic on save. No alarm-like repeating haptics.
- ✓Corrections stay auditable — times can be edited later; edited records show an Edited label.
Timing — start / end pickers, calculated duration, timed-in-app or manual.
A timing-only basic record is always valid.

A record your vet can actually use.
Short steps, saved as you go. History is reverse-chronological with date, duration, observation summary and media indicator — filterable by date, context, rescue medication and media.

Media stays intact
Sandbox storage with file protection, SHA-256, missing-file tolerance. A failed attachment never loses the event.

Taken / Late / Skipped
Scheduled vs. actual times kept separate; “Taken now” validated
Reminders never confirm a dose on their own. Late is your choice — no medical threshold is imposed. Estimated remaining decrements only for Taken / Late, with manual correction and a refill threshold you set. No dose calculations, no treatment advice.

What’s been recorded since the last visit.
Factual patterns only — weekly counts, duration trend, context counts, medication confirmations, calendar overview. Every chart ships with a text summary. The same immutable snapshot feeds the screen, the PDF and the CSV, so numbers can’t diverge.
