Telefon şarj durumunu saatte göstermek için indirdim. Bazen %1 hata payı olabiliyor ama normal. Görevini yerine getiriyor

Simple but clever

Cooles Tool, dass im Widget und Smart Stack den Akku-Status des iPhones anzeigt. Genau dafür ausreichend. Prima Support, schnelle Fehlerbehebung insofern für neue Anregungen. Gerne 5 Sterne dafür.
