Last chance for two App Store freebies

There are lots of iPhone app discounts to be had for the remaining 3 hours of the day (that's ET — different developers may trigger the return to regular pricing at different times, although I believe 'official App Store time' is PT), but two in particular caught my eye as excellent temp-free apps, and probably worth their regular prices as well.

Houdah Software's ACTPrinter addresses a longstanding challenge for the iPhone: how to easily get PDF files or other printables onto the device without having to email them to yourself. Using a driver on the Mac side to wirelessly ship the printed doc across to the device is a delightful approach to the problem, and from what I've seen it works like a charm (you can judge for yourself via this screencast). Such a bargain! ACTPrinter is normally $0.99.

For a different moneysaving strategy, check out MeterRead from Zerogate. This app (video demo here) lets you keep track of your electrical usage by saving and analyzing your meter statistics. Does the dishwasher use more power than the air hockey table? Do compact-fluorescent bulbs save major kilowatts, or just a trickle? You can find out with MeterRead; the developer cites a study that indicates 10-20% electrical savings for motivated consumers who analyze their usage. MeterRead is normally $2.99.
