EarOn Pro

EarOn Pro is the app dedicated to the EQ Tool, EQ Tool Pro and EQ Tool Pro V2 — the devices designed to help spearfishers and freedivers master ear equalization.

Equalization is one of the most important skills in freediving and spearfishing. Practicing it on land, in a controlled and measurable way, lets you reach deeper depths more safely and consistently.

WITH EARON PRO YOU CAN:
- Connect your EQ Tool, EQ Tool Pro or EQ Tool Pro V2 over Wi-Fi or Bluetooth
- Train different equalization techniques: Free, Frenzel, Advanced Frenzel, Sequential Frenzel, Mouthfill
- Visualize in real time the pressure curve generated by your equalization
- Set custom thresholds and limits (Equalization Threshold, Upper Limit, Lower Limit) for each exercise
- Get LED feedback directly from the device: green when in target range, red when outside limits
- Optionally record video and audio of your sessions to review your technique
- Save complete history of your training sessions
- Sync sessions to the kflow.pro platform for advanced analysis and sharing with your instructor
- Add notes to sessions to track progress and observations

EarOn Pro is a sport training tool dedicated to adult freediving and spearfishing athletes. It is NOT a medical device and does not replace assessment by a healthcare professional. Freediving and spearfishing carry inherent risks: always train responsibly, in a safe environment, and never alone in water.
