Take your flow to the next level! Riversurf IQ turns your Wear OS smartwatch into a dedicated sports telemetry and analytics tool engineered specifically for river surfing on stationary waves and wave pools, wakesurfing behind boat wakes, and surfskating on asphalt.

Riversurf IQ continuously processes raw 4 Hz triaxial accelerometer vectors directly on your wrist, automatically separating your active riding time from your waiting time in line.

*** ONE APP, THREE DISCIPLINES ***
Select your modality before dropping in:
• RIVER SURF: Optimized for river waves and artificial wave pools (Eisbach, Citywave, etc.). Features an anti-paddle filter that immediately halts tracking if you wipe out and swim to shore.
• WAKESURF: Designed for riding the boat's wake. Paddling penalties are disabled and speed thresholds are fine-tuned to accurately track long, rope-free runs.
• SURFSKATE: Bring ocean flow to the pavement! Calibrated to log continuous pumping, compression, and tight dry-land carves.

*** ADVANCED TELEMETRY (FlowScore System) ***
Upon kicking out of a wave or finishing a run, the watch processes locally:
• FlowScore (1–100): A weighted score based on your consistency, fluidity, and overall ride duration.
• Snap Score: Lateral G-force peaks measuring the aggressiveness and radicality of your turns and carves.
• Air Time: Weightlessness detection and landing impact analysis to clock your trick flight time in milliseconds.
• Complete Metrics: Total wave count, net wave time vs. queue time, distance, and top speed.

*** BLIND UX (Haptic Experience) ***
Keep your eyes on the water. The haptic engine guides you via distinct wrist vibrations:
• 1 Short vibration: Wave entry confirmed, tracking started.
• 1 Long vibration: Exit or wipeout detected.
• Wave Hog Alert: A subtle 60-second nudge in river mode to remind you to share the wave with the next surfer in line.

*** WEAR OS TILE & COMPLICATIONS ***
• Quick Tile: Add the Riversurf IQ Tile to your watch carousel for instant one-tap session launches and quick access to recent stats.
• Watch Face Complications: Display your session state and key ride data directly on your favorite Wear OS watch faces.

*** CLOUD SYNCHRONIZATION ***
Pair your watch with https://riversurf.xyz to analyze your speed charts wave by wave, compare personal records, and connect with the interactive spots map.

Compatible with Wear OS 3.0+ smartwatches (Samsung Galaxy Watch, Google Pixel Watch, OnePlus Watch, Xiaomi Watch, and more).
