The indoor rowing app that works as hard as you do
Whether you row at a gym, boathouse, CrossFit box, or home, Watta captures every indoor rowing session with AI-powered photo logging. No Bluetooth, no manual entry — just snap your PM5 screen and train.
The Problem
Indoor rowing apps are outdated or overly complex
Existing erg apps rely on Bluetooth pairing, require manual data entry, or bury useful features behind complicated interfaces. Indoor rowers need something fast, simple, and reliable.
Workout data disappears after each session
The PM5 screen shows your results for a few minutes, then resets. Without a quick way to capture this data, most indoor rowing sessions go unrecorded, losing valuable training history.
No community for indoor rowers
Indoor rowing can feel isolated compared to on-water rowing or group fitness classes. Most erg tracking tools are purely functional and lack the social features that build community and accountability.
