Chalk vs Arccos
Sensor-based shot tracking and AI caddie
Arccos uses grip-mounted sensors and an iPhone app to log every shot you hit, then feeds it into an AI caddie that suggests clubs and targets. It's the most data-rich golf app on the market. If you want sensors, GPS yardages, and machine-learning analysis, Arccos is the canonical answer. Chalk is the opposite: no sensors, no AI caddie — just a voice-first scorebook for players who like writing the round down themselves.
Pick Arccos if you want shot-level performance analytics. Pick Chalk if you want a quiet scorecard that lets you talk the round.

What Arccos does better
- Automatic shot detection means you don't have to log anything manually
- Years of detailed stats — strokes gained, club distances, dispersion patterns
- AI caddie recommendations are genuinely useful for course-management decisions
What Chalk does better
- Zero hardware to lose, charge, or replace
- Voice-first means you can score a hole without taking your gloves off
- Quiet by design — no leaderboards, no streaks, no notifications between rounds
Who should switch
Players who tried Arccos, found themselves looking at the phone more than the course, and want their scorecard to disappear back into the round.
Common questions
- Does Chalk replace Arccos's shot tracking?
- No. Chalk is a scorebook, not a shot-tracking system. If automatic shot detection and strokes-gained data matter to you, stay with Arccos.
- Can I use Chalk alongside Arccos?
- Yes. Plenty of players use Arccos for shot data and a separate scorecard for hole notes and observations. Chalk is built to be that scorecard.
- Does Chalk have a free tier?
- Yes. The voice scorebook is free. Pro features (cloud transcription fallback, AI round analysis) are a paid upgrade.
