Not bad, but

This is the first Basecamp companion app I tried. Its free, which is nice, and it seems to provide basic functionality Id expect to handle Basecamp tasks. The problems: (a) it has the same name as a for-pay app that does the same thing, but isnt the free "try before you buy" version of that; (b) it doesnt state anywhere on the website whether it does SSL connections; and (c) it doesnt seem to be developed actively at all, going by the state of activity on the app companys website. Worth a try, but it might be better to pay for another app if youre a heavy BC user.
