Now it's a 5 star app, but ... only in the "full version"

From the functionality and operation, there is certainly no better Spreadsheet App for Android than PlanMaker HD.
Although the functions in the basic version is very limited, but after a single payment of 4.99 EUR; you can use the full scope, which even exceeds the currently available PlanMaker 2012 from the Office suite for the PC.
But now comes the reason for the A - Star - rating: to be able to utilize the functionality, the program to authenticate with the server of the manufacturer has to connect, so you do not get to enjoy the purchased additional content without an Internet connection. Should be changed by the manufacturer by means of a program update, I'll adjust my assessment regarding the star yet, but at present it remains first with an asterisk, since I do not all have Wi-Fi on the tablet, then all paid functions actually allowed to use.

Update 05/08/2015: After I published this review, performed on 27.04.2015 on the Kommentatfunktion here to be contacted by a staff member of SoftMaker. Meanwhile, the issue is resolved and there are all over the in-app purchase made functions permanently even without an Internet connection. This means that both the app itself and SoftMaker have the 5-star earned. That you can never rule out such problems in advance all and try on all sorts of devices in very high market fragmentation of different devices and Androidversionen is unquestionable, but as exemplary as this responds to the support, which is very laudable and in this day and age more a rarity.

In summary it can be said that those who really want to work with tables under Android, not avoid the purchase of PlanMaker HD in the full version. Very big program really all imaginable functions, a top support and also very cheap for only 4,99 EUR. Now I can recommend the program without hesitation.
