Read full description

RepFlow ist dein minimalistischer Fitness-Begleiter für intensive Workouts. Zwei starke Tools in einer App – ein präziser Countdown-Timer und ein intelligenter Wiederholungszähler. **TIMER** Stell deinen Countdown-Timer mit einem Wischer ein. Während dein Training läuft, zeigt RepFlow den Timer direkt auf dem Sperrbildschirm und in der Dynamic Island an – du musst das iPhone nicht mal aufnehmen. Auto Reset startet den Timer automatisch neu, sobald er abläuft. Perfekt für HIIT, Tabata oder Supersätze. **COUNTER** Zähl Wiederholungen per Tipp – oder lass RepFlow einfach automatisch mitzählen. Mit aktiviertem Auto Count erkennt die App dein Bewegungsmuster über den Beschleunigungssensor und zählt jede Wiederholung sofort. Funktioniert bei Kniebeugen, Liegestützen, Bizepscurls, Sit-ups und vielen weiteren Übungen. **DESIGN** Klares, ablenkungsfreies Interface. Dark Mode und Light Mode werden automatisch dem System angepasst oder können manuell festgelegt werden. **HIGHLIGHTS** • Countdown-Timer mit Live Activity (Dynamic Island & Sperrbildschirm) • Automatisches Reps-Zählen per Bewegungssensor • Manuelles Tippen als Alternative • Auto Reset für ununterbrochene Trainingsblöcke • Flexibler Timer-Schritt (5 s bis 60 min einstellbar) • Dark Mode & Light Mode
