Swimlog keeps your log on your phone and asks for nothing it doesn't need. Every save lands on your device first — the cloud just keeps it backed up and in step across your devices.
Lives on your device
Core logging saves to your phone instantly and works offline. Scanning and cloud sync need a connection.
Backed up automatically
Your log backs up to the cloud in the background and stays in sync across every device signed in to your account.
Yours to delete
Delete your account in-app and your data is permanently wiped — on our servers and on your device alike.

Questions, answered
What is Swimlog: Pool Tracker?
Swimlog: Pool Tracker is the swim training log at swimlog.dev for competitive, college, masters and committed swimmers. It is developed by Edward Baltaza for iPhone on iOS 18 or later, App Store id 6775411816. Type coach shorthand, scan whiteboards, review editable sets and keep training, racing and team practice in one log.
Can I import Apple Watch swims?
Swimlog imports compatible Apple Watch and other HealthKit pool swims through Apple Health for 25 yd, 25 m and 50 m pools. Access is optional and read-only: workout distance, duration, laps, strokes and timing, with no heart rate, calories, routes or open-water workouts and no writes to Apple Health.
How much does Swimlog cost?
Swimlog Pro requires a monthly or yearly subscription after account setup. Eligible users may receive a 7-day free trial. Prices and eligibility are shown before purchase. Manage or cancel subscriptions in App Store account settings.
Do I need an account?
Yes — a quick email sign-up or Sign in with Apple, so your log belongs to you, stays backed up, and can move between your devices. And it's yours to take away: deleting your account wipes your data from our servers and your device alike.
Does it work offline?
Core logging works offline: every set saves to your phone and cloud sync catches up when you reconnect. Whiteboard scanning, account setup and team updates need a connection.
How does the whiteboard scan work?
Tap the camera in the capture bar and photograph the coach's board — or pick a photo from your library. AI reads the board into shorthand sets that appear in your draft for review; anything it can't read lands in your notes, and nothing is logged until you tap LOG. Photos are downscaled and stripped of location data before they're processed, and scans have a fair-use daily limit.
How does shorthand capture work?
Type a set such as 4x100 free @1:30 and review the structured draft. Check repetitions, distances, strokes and send-offs, edit the details and save only what you actually swam. You can also build and edit sets directly.
Do you track me or show ads?
No ads, ever — and no ad trackers, no advertising identifiers, and we never sell your data. Beyond its own secure backend (Supabase) for sign-in and sync, the public App Store release uses a little privacy-respecting, first-party analytics and crash reporting (Sentry and PostHog, both EU-hosted) so we can fix bugs and make the app better. PostHog is disabled in TestFlight and never records screens, touches, or anything you type. It's never used for advertising, and you can opt out by emailing us. Full details are in the privacy policy.
What can my teammates see?
Only if you join a team — that's the whole decision. Teammates can see shared training volume and your swims in the chronological Team Log, where they can leave a reaction or a comment. Your email is never shared, you can block or report anyone, and leaving the team stops the sharing.
When does Swimlog ask for notifications?
Only if you enable reminders. Weekly digest and streak notifications are optional, off by default, and scheduled locally by your phone — Swimlog does not send their content to a push server.
Can I delete my account and data?
Any time, right inside the app, under Profile → Delete account. It permanently removes your data from our servers and wipes everything stored on your device — no email request needed.
Which pools and strokes does it support?
Short-course yards (SCY), short-course metres (SCM) and long-course metres (LCM); all four strokes plus IM. Each workout is stored in its native unit and only converted for display, so mixed-pool totals stay honest.
