Grassy vs. Arccos Caddie: Planning or Automatic Shot Tracking?
Arccos is an automatic game-tracking and AI-caddie ecosystem built around its app, shot-detection hardware, and membership. Grassy is a ranking-first iPhone app whose Course GPS Beta includes all current planning tools for everyone, without requiring club sensors.
Grassy Course GPS is currently in beta, and Grassy is currently on iPhone. Course eligibility and advanced map detail vary.
Grassy is best for
iPhone golfers who want course ranking and social discovery connected to full-round GPS planning, scoring, and supported-course LiDAR and 3D detail without club sensors or a GPS subscription.
Arccos Caddie is best for
Golfers who want automatic shot tracking, personalized AI strategy, smart club distances, and strokes-gained analysis through a connected hardware and membership ecosystem.

Side by side
How the product focus differs
| Priority | Grassy | Arccos Caddie |
|---|---|---|
| Core identity | Course ranking, discovery, friends, scoring, and Course GPS Beta in one iPhone app. | Automatic game tracking and AI-caddie platform connected to Arccos shot-detection hardware. |
| Getting started | All current Course GPS Beta planning tools are included for everyone on an iPhone running iOS 18.0 or later; eligible-course detail varies. | The reviewed sensor workflow pairs Smart Sensors with the app and a phone, Arccos Link, or Apple Watch; Arccos says sensor shot detection requires an active membership or trial. |
| GPS guidance | Measured and plays-like distance can use available wind, elevation, temperature, and altitude, with club suggestions when a bag is configured. | Arccos promotes an AI GPS Rangefinder with real-time adjustments for wind, slope, temperature, humidity, altitude, and related conditions. |
| Shot tracking | Grassy does not currently claim automatic shot tracking, Apple Watch GPS, or club-sensor support. | Sensors detect impacts and the selected phone, Link, or Apple Watch records shot location so Arccos can map and categorize the shot. |
| Planning and analysis | Draggable hazard and layup targets, both-leg distances, adaptive arcs, scoring, and supported-course LiDAR and 3D tools focus on planning the current round. | Smart Distances, AI Strategy, personalized targets, and strokes-gained analytics use tracked performance to guide decisions and improvement. |
| Course record | Personal rankings, lists, friend activity, and discovery keep the courses themselves central before and after the round. | Arccos emphasizes a golf journal and detailed shot, club, round, and performance history. |
The decision
Which one fits?
Choose Arccos if automatic shot capture, AI strategy based on your tracked game, and strokes-gained analysis justify a connected hardware and membership workflow. Choose Grassy if you want course ranking and discovery tied to advanced iPhone planning tools included for everyone, and you do not need automatic tracking, a watch workflow, Android, or universal advanced-map coverage.
