1. 센서들을 등록하고 연결되었다고 했는데 로그 시작 시 하나도 연동 안 되어서 스피드, 케이던스, 심박 등 정보가 하나도 반영이 안 되었습니다. 앱에서 기록을 시작하려고 할 때에는 심박이나 다른 정보가 정상적으로 표시되지만 기기에서는 전혀 나오지 않습니다. 그리고 기기가 gps로 속도를 받아서 표기할 때 점멸되어 몇 초마다 현재속도가 나와요. 이게 정상인가 싶네요.

2. 첫 페이지 구성을 변경하려고 할 때 한국어 사용자인데도 스페인어로 용어가 표기되어 있어요.
누르고 나면 한국어도 아니고 영어 약자로만 정보가 나오는데 어떤 용어는 정확히 무슨 정보를 말하는 건지 파악하기 어렵네요.

Удушение функционала

Очень не хватает возможности редактировать записанный трек. Иногда gps некорректно начинает запись или сбивается из за слабого сигнала, из за этого данные по тренировке некорректные. Добавьте возможность записи дистанции только по датчику на колесе что бы расстояние верно писалось.

Fiz meu treino hoje dia 04/07/2026 meu xoss salvou a atividade do mata, porém não sincroniza com o Strava. Hoje está com esse problema e já fazem 6 horas depois da minha atividade e ainda não sincronizou a atividade para o Strava..🤦🏻‍♂️

Not good…no stars

The cycpro m2 stopped working after the first day. I have one day using the app and it constantly dropped the connection to the device.

Update: Cycplus fit app is the app that cycplus maker supports. They no longer support this app. They said the firmware update in this app has broken other devices of theirs. Use cycplus fit app not xoss.
