As we do with our website, we will continually update the app as we discover new tuning information.

In certain situations you can benefit from increasing your gear ratio when HP is low & decreasing your gear ratio when HP is high.

This is a guide to America's best-kept golf secrets — over 1,600 handpicked public and semi-private courses across the country that the everyday golfer has earned the right to know about. Courses with character. Courses with history. Courses with a $30 green fee and a bar where the locals have been drinking since 1978. The kind of round you'll be talking about on the drive home. The average weekday rate across our courses is $49. Over 90% are under $75 out the door. DISCOVER COURSES YOU'VE NEVER HEARD OF Every course in Hidden Fairways is rated across 11 categories — course quality, scenery, value, conditions, pace of play, walkability, bar, food, local vibe, road trip worthiness, and a hidden gem score designed to surface the places most apps will never bother showing you. Courses are tagged for what they do best: scenic terrain, water features, walkable layouts, replay deals, budget-friendly, resort-style, and more. Filter by what matters to you on any given day — whether that's the cheapest round in the state or the most jaw-dropping back nine within two hours of home. Over 538 courses are flagged as Worth the Drive. These are the ones you plan your weekend around. PLAN A GOLF ROAD TRIP 74 curated road trips built around the best courses in each region of the country. These aren't random lists — each trip is a real multi-day route built for golfers who want to get in the car and go. Midwest value runs. Great Lakes classics. Desert canyon layouts in the West. Mountain tracks in the Rockies. Coastal loops in the Southeast. There's a trip for every budget, every region, and every kind of golfer. Browse by region, pick your route, and have a full itinerary waiting before you finish your coffee. THE 19TH HOLE, RATED Most golf apps tell you whether a course has a bar. We tell you whether it's actually worth going to. Every course with a bar or restaurant gets a dedicated bar score — backed by real reviews from Google, Yelp, TripAdvisor, and golf forums. We're talking about the places with a Friday fish fry that sells out by noon, the clubhouses with 16 local beers on tap and a sunset deck that faces the 18th green, the dive bars tucked behind a $28 muni where the beer is ice cold and the stories are better. The 31 courses with a 9.0+ bar score are the real ones. Not paid placements. Not guesses. Earned. INSIDER KNOWLEDGE, BUILT IN Every course comes with an editorial summary written to tell you exactly what you're walking into — the personality of the place, who plays there, and what makes it worth your time. Plus insider tips: which tee time gets the best conditions, which hole will cost you a sleeve of balls, whether the cart girl comes around on weekdays, and what to order at the turn. Course details include best season to play, nearby lodging options, and a bestFor tag that tells you at a glance whether this is a bucket list round, a locals' favorite, a cheap weekday grind, or a resort stay worth building a trip around. TRACK WHAT YOU'VE PLAYED Log every course you've played and build your bucket list as you go. See how many hidden gems are sitting within driving distance that you haven't touched yet.
