Have me as part of the free TagesApp Amazon sometimes the Key for D2Go ge "buys". I've tried a few (!) Office programs. On my last phone I AbiWord uses for which it probably unfortunately no Android port is, except on a Debian (derivative) emulation. 90% ++ I use word processing on phablet, the rest is mainly spreadsheet. For pdf to specific programs offer. Compared with the other Office programs (some are generally free, Samsung has for most of its equipment another app free and also paid can with regular use make sense) D2Go is simply worse by far. I had it "for me" anyway have already retired on the "I do not have to have" stacks. After the key Amazon has offered free I D2Go again looked at in more detail, but I am come to the conclusion that it is not competitive. If I remember correctly, there was at the time probably already V4? Maybe that was an action the customer to buy from V4 to move - for me that is but then totally failed. D2Go would I use most when "I (enough) for would get money or it would be the last Office program on earth" ... Say all I tested programs it has in me produced the worst impression what functions and service concerns. Even the generally free apps were better. Who is willing to take some money in the hand (provided that its hardware provider offers no special offer) should be times OfficeSuite Pro and / or QuickOfficePro look. Every now and then there are also special promotions in stores, if I remember correctly, there were Quickoffice sometimes even from Amazon as daily offer.
