The difference

Most golf apps track shots.
Yipshanks remembers conversations.

Tag who you played with. Write what you talked about. Encrypted on your device, never synced. Tee off with that same person six weeks later and the note resurfaces before the first hole. You walk into the conversation already in stride.

Features

Everything golf, nothing extra.

The bits the paid apps charge for, free and yours, in any browser.

Live tournaments & leagues

Host in seconds. Players join with a code or QR. Spouses, kids, sponsors, friends follow the leaderboard in any browser. Tag multiple events under one league or series name and Yipshanks rolls them up into a combined standings page.

Satellite course views

Real aerial imagery for every well-mapped course, with the property boundary traced in brass on top. One-time fetch, cached locally on your device. Not a GPS tool. Mapbox imagery, OpenStreetMap outlines.

Private notes

Tag who you played with. Write what was talked about. Encrypted on your device with AES-256-GCM, never synced. Resurfaces before your next round with that person so you walk in already in stride.

Six game formats

Stroke, scramble, skins, stableford, match, best ball. 9 or 18 holes. Up to four players. Optional per-hole stats when you want the depth.

Estimated WHS handicap

Computed locally with the official formula. Always labeled estimated, never claimed as official GHIN. Activates after three rounds.

Trends & personal records

Score-to-par trend, format and course mastery, longest improving streak, total birdies and eagles, your strongest tracks, friendly-wager pot record.

AI coach, your key

Optional. Bring your own Anthropic, OpenAI, or Gemini key. The coach reads your rounds and answers your questions about them. The conversation never leaves your device.

Sponsor-ready scorecards

Beautiful share cards as PNG or PDF, a QR that gets scanned at the 19th hole, your footer line, and an optional sponsor credit for charity events.

Mental game layer

Pre-round breath, intention, body check. Post-round reflection. Off by default, on for the rounds that matter.

Friendly wager tracking

Optional. Log the stakes, mark the winner, build your pot record over time. Yipshanks does not handle or process money — it's a record-keeping field, no different than writing the bet on a scorecard.

Per-hole yardages

Static layout detail on the scorecard. Pulled from the preloaded library for known courses, or enter the tees you actually play.

Demo mode

Realistic synthetic data including the NSF Charity Cup series — three events, one combined standings page. See exactly what year two on Yipshanks looks like before round one. Separate database; your real data stays clean.

Privacy

Your game is yours alone.

No accounts. No tracking. No analytics. The whole product is open source and audited by the people who use it.

  • No account required. Open the app, start scoring. No sign-up, no email, no phone number.
  • Zero telemetry. No analytics, no crash reporting, no tracking libraries. Ever.
  • Local-first storage. Rounds, courses, stats, and notes live on your device. The relay only sees what you publish.
  • Encrypted at rest. Notes and AI keys sealed with AES-256-GCM under a non-extractable browser key.
  • Open source on Codeberg. AGPL-3.0. Audit it. Build it. Fork it. Stays free forever.
  • Your AI key, your provider. Calls go straight from your browser to your chosen provider. We never see them.

Justin Chase Ford

Licensed financial professional. Marine Corps veteran. Developer behind Yipshanks, Nemorith, and Finaxius. Built Yipshanks for the golfers in his life because the rounds matter, and the tools should respect that.

Great with portfolios. Catastrophic with a 7-iron. The name basically narrates the round. Whether you're brand new or playing scratch, you're in good company here.
