What Arccos actually is

Arccos is a hardware-plus-software system. You install small sensors into your clubs (or use sensorless tracking via Arccos Air, a wearable launched in 2026), and the system automatically detects and logs every shot you hit during a round, no manual tagging required.

From there, the Arccos app gives you tour-level statistics: strokes gained for driving, approach, short game, and putting, true average distance per club with mishits filtered out, and an AI caddie that recommends club selection and target lines based on a dataset of over a billion recorded shots. It also functions as a GPS rangefinder on the course, adjusting yardages for wind, elevation, temperature, and humidity.

This is a genuinely serious tool for golfers who want to understand exactly where their strokes are going, hole by hole, club by club. It's also why Arccos is used by some competitive amateurs and even referenced by tour pros.

What GolfIQ actually is

GolfIQ doesn't try to compete on shot-level data. It's built around a different question: how do you stay connected to the golfers in your life between rounds, and see your overall handicap trend without needing hardware?

You log a round (course, score, date) in about 30 seconds. From there, GolfIQ shows your handicap trend over time, your personal records, your course history, and, the part Arccos doesn't really touch, a live friend feed that shows when people in your group post a round, hit a personal best, or move up a leaderboard.

Where Arccos is genuinely better

We're not going to pretend GolfIQ does this stuff, because it doesn't, and isn't trying to:

  • Shot-level data. Arccos tracks every individual shot automatically. GolfIQ tracks at the round/score level, not per-shot.
  • Club-by-club distance and strokes gained. If you want to know your real 7-iron distance or where strokes gained analytics say you're actually losing shots, Arccos's sensor data is built specifically for this and does it well.
  • On-course AI caddie and GPS. Arccos functions as a real-time rangefinder and strategy tool while you're playing. GolfIQ is built for logging and reviewing, not in-round strategy.
  • Course mapping depth. Arccos has tens of thousands of courses mapped with green-level detail for its caddie features.

If your goal is lowering your scores through granular data and you're willing to install sensors and pay for hardware plus a membership, Arccos is the more mature, purpose-built tool for that specific job.

Where GolfIQ is genuinely better

  • The social layer. Arccos doesn't have a live friend feed or a way to see your group's rounds in real time. GolfIQ is built around exactly that.
  • Group leaderboards. GolfIQ's Groups feature lets a regular foursome run a season-long leaderboard. Arccos is built around individual performance, not group dynamics.
  • No hardware required. GolfIQ works from your phone alone. Arccos requires either club sensors or a separate wearable device to get the automatic tracking experience.
  • Lower cost of entry. GolfIQ's core features are free forever. Arccos requires a hardware purchase (typically a few hundred dollars) plus an ongoing membership after the included first year.
  • Simplicity. Logging a round in GolfIQ takes about 30 seconds. Arccos's depth is a strength for data-focused golfers, but it's also a heavier lift if all you want is "track my score and see my friends' rounds."

Who should use which

Use Arccos if

You're a competitive or data-driven golfer who wants to know exactly where every shot goes, what your real club distances are, and where strokes gained analytics say you're actually losing strokes. You're willing to install hardware and pay for a membership in exchange for the most granular data available.

Use GolfIQ if

You play golf as much for the people as the score, and you want a dead-simple way to track your handicap trend and stay connected to your group between rounds. You don't want to install sensors or pay for hardware just to log a round and see how your friends played.

Or honestly, use both

These tools aren't mutually exclusive. A golfer could reasonably use Arccos during a round for shot-level data and the on-course caddie, then log the final score in GolfIQ to keep the handicap trend and friend feed updated. They're solving different problems, and there's no real conflict in running both side by side.
