Really wanted to like this app. I find the metrics are more indicative of actuals. On par performance with athyltic, however, complications on watch face are an unoptimized mess that make the watch UI lag. I have tried to use on an Apple Watch Ultra, so a top tier Apple processor and having bevel complications kill the UI smoothness. In comparison, athyltic runs buttery smooth with equivalent complications on the watch face. I don’t want to pay for a top tier Apple product to just have the experience ruined because of a poor app. If the app was better designed and not a UI killer, I’d buy it. For now I will remain a paid member of Athlytic.
