Tidal Labs turns your watch and iPhone into a hands-free surf filming system. Works with Apple Watch or a compatible Garmin! Set up your iPhone on a beach tripod or mount pointed at the lineup, strap on your watch, and paddle out. When you catch a wave, log it from your wrist: scroll the Digital Crown up on Apple Watch, or press DOWN on Garmin. When your session ends, open Tidal Labs, import your iPhone footage from your camera roll, and sync your watch data. The app automatically matches your timestamps to the footage and trims each ride into its own clip. The result is a clean highlight reel of every wave, ready to share, without touching a single clip manually. HOW IT WORKS 1. Mount your iPhone on the beach pointed at the waves 2. Start a session on your watch before paddling out 3. Log each wave from your wrist as you ride it 4. After your session, open Tidal Labs and import your footage from your camera roll 5. Sync your watch data and the app automatically trims your highlight reel FEATURES • Wave timestamps from Apple Watch or Garmin • Import footage directly from your camera roll • Automatic clip trimming based on ride timestamps • Landscape clip editor with trim and non-destructive crop • Optional GPS and on-device vision auto-follow crop • Auto surf spot detection powered by Surfline • HealthKit workout tracking with live heart rate • Configurable clip length (30 seconds to 3 minutes) • Session library with favorites and clip management • Save highlights to your camera roll and share anywhere • Everything stays on your device. Your footage is never uploaded • Clean, surfer-focused interface All you need is your iPhone, your watch, and some good waves.

Verdict
The clearest difference is ratings volume: Retro Flash at 226 against Tidal Labs's 1. Retro Flash also leads on iOS requirement (15.6 vs 26.0). Tidal Labs's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Retro Flash sells 8 one-off in-app purchases and Tidal Labs sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Tidal Labs holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Retro Flash has 226 ratings behind it against 1, so its average is the more settled of the two.
Retro Flash ships an update every 3 weeks, Tidal Labs fortnightly. The most recent releases landed on October 24, 2026 and October 7, 2026 respectively.
