What's the difference between Teers and Mulli's rating systems?

Mulli uses 5-star ratings. Teers uses sentiment tiers (Elite, Great, Alright, Bad) with a re-rank flow that can promote a course up to the next tier. Tiers map more naturally to how golfers actually talk about courses.

Does Teers have an international course database like Mulli?

Mulli has 17,000+ international courses. Teers is US-focused with API fallback for international courses — if you golf abroad regularly, Mulli's database is currently larger.

Can I import my 18 Birdies rounds into Teers?

Yes. Teers imports your course history from 18 Birdies via CSV or photo OCR. Mulli supports manual 'Replay rounds' backfill but doesn't import from other apps.

Does Teers have leaderboards like Mulli?

No. Teers deliberately doesn't rank users by 'most courses ranked' — we think that incentivizes volume over taste. Mulli has community leaderboards for who's ranked the most.

Teers vs Mulli — Comparing two new golf course ranking apps

If you're trying to choose between Teers and Mulli, you're looking at the two newest entrants in the "rank the courses you've played" category. Both apps believe golf needs an identity layer that lives outside the scorecard. Both are free. Both are iOS-only. Both are early.

The differences are in the details — and the details matter.

Where Mulli is stronger

Larger course database. Mulli's 17,000+ international courses is a real advantage if you golf abroad or want courses from outside the US. Teers focuses on US courses with API-fallback for anything else.

Creator profiles + DMs. Mulli has verified creator profiles with linked social channels and merch, and they shipped DMs/group chats in May 2026. If you're following golf influencers, that infrastructure is real.

Older / more shipping cadence. Mulli launched September 2025 and is on version 3.0.7 — they ship fast.

Leaderboards. If gamification motivates you to rank more courses, Mulli's leaderboards for "who's ranked the most" give you that loop.

Where Teers is stronger

Ranking by tier, not stars. Star ratings are blunt — every "4.5 star" course feels the same. Teers groups courses into Elite, Great, Alright, and Bad (yes, Bad is a tier — some courses earn it). The conversation matches how golfers actually talk. "Yeah Pebble was Elite. Sand Hills, also Elite — but a different kind of Elite."

Phone contact match for friends. Teers hashes your contacts on-device and shows you which people you already know are on the app. You don't hunt usernames or pass invite codes. Your group chat populates on day one.

18 Birdies import. Coming from 18 Birdies? Teers imports your course history via CSV or photo OCR. You start with a real ranked list, not a blank slate. Mulli's "Replay rounds" feature lets you backfill manually but doesn't pull from other apps.

Predicted score badges. Look at a course you've never played and Teers shows what we think you'd rank it based on your taste profile and your friends' rankings. Mulli shows you community averages — Teers shows you your predicted score, which is much more useful.

Quality over quantity. Teers doesn't rank you by "most courses ranked." We think that pushes people to log every muni they've ever played, which dilutes the signal. Your top 10 should mean something. Mulli's leaderboard rewards volume; we reward taste.

Re-rank flow that respects context. Bump a course up at the top of "Great" and it auto-promotes to Elite. Bump the last "Elite" down and it slides into Great. Five-star ratings can't do that.

Which one should you use?

Use Mulli if: You play internationally and need their global database, you're following golf creators and want their verified profiles, or you like the leaderboard-as-motivation loop.

Use Teers if: You'd rather rank by tier than by stars, you want your friends imported from contacts automatically, you're coming from 18 Birdies, or you care more about the quality of your top 10 than the size of your total list.

Both apps are betting on the same idea — that golfers want a place to rank the courses they've played and compare with their friends. The category is wide open. Try both. The one you keep opening wins.
