Thanks for the update on Presearch. I have been using it from the start, but due to circumstances, I haven't been able to these last two months. Just yesterday I logged into my account again, but didn't pay any attention to my balance. After reading your post I went to check, only to find out one account had been emptied. Guess it was my own fault for having two accounts (I opened a new one because I wanted to use a different email address - both had tokens in it. But not anymore...)
Anyway, I really like the concept of Presearch. It's convenient to be able to customize your serch engine for every search - and of course it's great to be paid to do what you do anyway.
And I will look into the Actifit app as soon as they release their IOS version
