Detailed Breakdown

Apple Fitness is what most iPhone users encounter first when they start rowing. Start an indoor rowing workout on your Apple Watch, and it tracks heart rate, calories, and duration. It is seamless and automatic. But that is where the rowing intelligence ends. Apple Fitness has no concept of split time — the fundamental metric of erg performance. It does not know your stroke rate, cannot calculate watts, and has no idea whether you paced your 5K evenly or blew up at 2,000m. It treats rowing exactly like an elliptical session: heart rate and time. Apple Fitness+ adds guided rowing classes with enthusiastic instructors, which are genuinely motivating for beginners — but they do not solve the analytics gap. Watta fills this gap precisely. By reading your PM5 screen, it captures the data that Apple cannot access from your wrist. The Effort Score then analyses that data through a rowing-specific lens, giving you actionable insight on every session. For Apple Watch owners who row, the recommendation is simple: wear your Watch for heart rate and close your rings, then photograph your PM5 for Watta to get the erg-specific analytics.
