Danke ### 5/5 — Design Flop, Funktion Top *2022-04-26, version 1.4.1* Zugegeben, das Design ist bestimmt Geschmackssache, mich hätte es fast abgeschreckt, die App macht aber genau das was sie soll… ### 4/5 — Herzlichen Glückwunsch! *2014-10-22, version 1.3.3* Sie bieten als einziger eine App mit dieser Funktion. Es funktioniert gut! Mit dem Zusatz mehrere Industriezeiten und/oder normale Zeiten in einer Rechnung zu addieren oder subtrahieren gäbe es noch einen Punkt mehr. Also zB 2 Std 35 Min + 1 Std 12 Min = 3 Std 47 Min ### 5/5 — Dezimalrechner *2013-05-18, version 1.3.2* Top, ist eine grosse Hilfe bei Rechnungserstellung. ### 5/5 — Geniales Tool *2012-06-09, version 1.2.2* Macht genau das was ich gesucht habe und brauche.
