Back to the usual review this week, after our 20 Essential Apps list last Friday. Thankfully, it's been a pretty good week in the store, with lots of actually useful apps—including a full-fledged four-track recorder and a couple of utilities that actually add some usable core features that I wish would have made it into the 2.2 software update today. Oh, and of course, something Japanese and crazy. Onward! Four Track: Remember how Keith Richards always said he recorded the riff to Satisfaction on a hotel answering machine? Well, now, budding Keefs can multi-track their sudden inspirations for songs about not getting sufficiently laid. Four Track offers all the controls you would want for a basic deck, has no track length limit, and can sync via wi-fi to import you recordings into Garage Band or Pro Tools. Awesome. It's $10.
Save My Docs: Safari received some nice performance and UI tweaks in 2.2, but it still does one thing a mobile browser should never do—wipe out version of pages you've already loaded for no reason. Multiple times I've loaded a long Wikipedia article on something that I planned to read on the subway, only to find the page totally blank a few minutes later for no explicable reason. Save My Docs does one thing—saves any document loaded in Safari locally, complete with images, to be read at any time later. $2
CalToDo: I can't believe this isn't a native feature: CalToDo easily syncs your OS X to-do lists (found in Mail and iCal) via a lite server app that runs on your machine. Interface is nice, and so is the simplicity. $1
iMarimo: And iMarimo, what can I say? It's floating ball of algae in front of a few blurry pictures that you can spin via touch. Apparently, the Marimo algae is beloved in Japan for its freakish, perfectly spherical growth and its ultra-rarity—found only in a single lake in Hokkaido. Damn. That's about all I can say about this on a Friday, and it costs $1.
