Hi Hotspur (Chris),
For 12.70 euro everybody gets the right to use APT for life-time. There are no functions expiration. Every single feature that is added to APT during the next year will be in your hands. One year latter (or more) you can decide if you want to support the future development or not. The support will be rewarded again with every single feature - no matter if it is major or minor one. What is the price? It is 6 euro. But if you are happy with APT and don't need new things, then I'll be more than happy because APT fits your needs and I had done my job well
