Zuverlässiges Uhrenmanagement

Mit der Zeit habe ich so an die 10 „Schätze“ angesammelt. Wenn ich die Schachtel der Uhren nach langer Zeit öffne graust es mir wie verkehrt die Uhrzeiten wieder laufen. Mit dieser App kann ich endlich jederzeit beobachten und abschätzen wie meine Uhren laufen. Wenn ich eine Uhr verleihe, sehe ich ob diese umgestellt wurde und kann ggf. bei der Person nachhaken. Die gibt mir so viel Klarheit. Ich kann die App nur empfehlen!
