Built for Nordic swim clubs
Lightweight, affordable timing for unsanctioned and recruitment meets. Volunteers use phones as timer units, a mother device coordinates the start, and the audience follows the results live on TV and the web.
The problem
Most Norwegian clubs run unsanctioned meets with stopwatches, paper sheets, and an operator typing in times after the fact. It's slow, error-prone, and the audience never sees results until the next day.
150–300 ms human reaction time per volunteer. Six lanes turn into six different truths.
Entries in spreadsheets, heat sheets on A4, results in a binder. Easy to lose, hard to share.
Parents stand around waiting. Results get published the next day — if at all.
Omega and Colorado timing systems start at €20k. Out of reach for small clubs.
How it works
Your club registers for free, sets up the meet in the browser, and runs it with the phones you already own. No extra hardware, no installation.
An admin creates an account and gets approved. Roster, pools and volunteers are set up once and reused for every meet.
Build the start list in an evening: add events with one click, import entries via CSV/Excel, and generate heats with circle seeding automatically.
The mother device (laptop/iPad) shows a QR code. Volunteers scan with their phone, get assigned a lane, and tap STOP when the swimmer touches the wall. The TV display and web update live.
Features
iSwim covers the entire flow from entries to published results. Built with Norwegian clubs, for clubs anywhere.
Circle seeding across heats, inside-out lane assignment, and one-click 'Generate all heats'. Scratched entries are filtered automatically.
QR pairing at poolside. Median aggregation across 1–3 phones per lane. A stable deviceId survives crashes and reconnects.
A large live clock, place medals in real time, and a mobile-optimized /m/ page parents can share with anyone at home.
Shareable invitation links. Invited clubs upload their entries via CSV or Excel — no login required.
Start lists as PDF, results as CSV. Not locked in — your data is downloadable any time.
Results are free for the public to view at iswim.no/m. No login, no paywall, no tracking.
Times are stored locally on the phone in IndexedDB if the network drops, and sync back when connectivity returns. No times lost.
All data is stored in the EU (Neon Postgres + Upstash Redis in Frankfurt). DPA template in Norwegian. Passwordless sign-in via magic link.
Bokmål by default, English for international meets and volunteers. Date and number formatting follows nb-NO.
The answer
iSwim turns volunteers' everyday phones into synchronized timing units. A laptop coordinates the start. Times are aggregated in real time and published to a TV display and the web for spectators.
Volunteers scan a QR code, the phone gets assigned to a lane, and a giant STOP button is the only thing they need to use during the heat.
Shared start signal over WiFi, median aggregation across 1–3 phones per lane, automatic outlier filtering. Not approved for sanctioned meets — built for recruitment and unsanctioned use.
Results are pushed to the TV display in the pool hall and the public spectator page in the same second the last swimmer touches the wall.
Pricing
Every club can register for free and view rosters, invitations and published results. You only pay when you actually run a meet.
Pilot clubs: no payment is required during the pilot phase. Pricing is being validated with real clubs before the paywall is enabled.
One meet, unlimited swimmers. Access expires 7 days after the end date.
One meet with 200+ swimmers. Same features, more support bandwidth.
Unlimited meets in one calendar year. For clubs that host regularly.
Real billing via Stripe and Vipps ships in phase 8 of the iSwim project. Until then, the 'Start free trial' button works as early sign-up — we'll get in touch before the first invoice.
FAQ

One laptop or iPad as the mother device, one phone per lane (preferably two for redundancy), a wired speaker over 3.5mm or USB for the start signal, and a TV or projector for live results (optional). Most clubs already own all of this. Do NOT use a Bluetooth speaker — it adds 150–250 ms of latency that ruins timing accuracy.
The timer phone records stops locally in IndexedDB and syncs them back to the server as soon as the connection returns. The connectivity indicator shows 'Offline (N swims queued)' so the volunteer knows the times are safe. The mother device has its own reconnect logic and rehydrates state from Postgres + Redis after a restart.
Total system error is ~100–200 ms (the shared start signal over WiFi has 10–80 ms jitter, phones use performance.now() for monotonic time, and median aggregation across 1–3 phones per lane filters outliers). That matches manual stopwatches but is NOT approved for sanctioned competitions — it's built for recruitment and unsanctioned meets.
All data is stored in the EU (Neon Postgres and Upstash Redis in Frankfurt). We only process names, birth dates, sex, club, entries and times — no addresses, phone numbers or national ID numbers. Results are kept for 2 years by default; clubs can request deletion. A Norwegian-language data processing agreement (DPA) is signed with every paying club. We use Vercel Analytics as a GDPR-friendly alternative to Google Analytics.
Not in the MVP. iSwim is built for unsanctioned meets and recruitment meets that aren't reported to medley.no in the first place. Export to the Norwegian Swimming Federation's national results database is on the roadmap but is not a prerequisite for iSwim to work for your club.
Yes. Any club can register for free and create a test meet to learn the workflow. Pilot clubs through 2026 run for free in exchange for feedback. Email admin@iswim.no to become a pilot.
All data can be exported to CSV and PDF at any time — start lists, entries and results. There's no lock-in. Your club owns its data.
Pilot 2026
We're taking on a limited number of clubs through 2026 to run iSwim for free in exchange for feedback. After the pilot phase, pricing is as listed above.
