Been a while since I added to my list of recommended apps:
iPics Lite Long story here... I finally got around to getting my digital photos organized. Part of that was looking for a way to view everything on my iPhone. Syncing to the phone itself takes up too much space, so I started looking for cloud storage & viewing solutions. Flickr is pretty much universally recommended, but it's pretty limited unless you pay for a premium subscription. To me it looked better suited to people who want to share/publish their photos. It turns out Picasa Web Albums did everything I needed for free. They don't have an official Picasa app however. Like many other Google products they have a web app, but I prefer a native app on my phone because it seems snappier and less of a drain on my battery. iPics Lite does the trick, it's free and it has a user-friendly interface. There is a full version as well, but I honestly don't see any premium features that I find useful. Anyway, it's a pretty good app.
Musica/BookKeeper These are two separate apps, one for cataloging your music collection and another for cataloging your book collection. The original app from this developer was created to catalog DVDs, and both of these were ported from it. Even in this digital age, I still collect CDs and hard copy books. I'm slowly but surely "legalizing" my mp3 collection with used CDs, and I buy a lot of old, cheap paperback books (I kinda collect ones with vintage cover art.) Since I've been buying so much lately, it's difficult to keep track. This app lets me know what I still need to buy and keeps me from buying duplicates by accident. I tried pretty much all of the similar apps from other developers, and these were the best. As a group, none of these cataloging apps are perfect - in fact, most of them kinda suck. Barcode scanning is inconsistent at best, search options are often limited and manual entry is tedious and difficult. These two apps were the least problematic in these areas, and were also the best-looking, smoothest-running apps of their type. It took a long time to get up and running with them, but they've become indispensible and easy to maintain once it was all set up.
Dropbox Cloud computing at its most basic and functional. Add files to your Dropbox folder on one of your computers, it becomes available on all of your other devices either via the web or in the Dropbox folder on other devices where you have the client installed. I do a lot of document editing for my job. This allows me to pull up the most recent version and view it or edit it from anywhere. As long as you're saving it to your Dropbox folder it syncs automatically. Keeps me from having to constantly update a flash drive or email the newest drafts to myself. Also, a lot of other apps are integrating Dropbox - for instance the Musica app I mentioned above allows backup/restore from Dropbox - a simple way to give a little peace of mind to somebody who took the time to enter almost 800 albums into the app.
Tiny Wings My new favorite game, and the new king of the App Store. It has overtaken Angry Birds for the top spot and held on to it for the last couple weeks. Simple controls and a unique gameplay idea. It looks and sounds great, is fun to play and addictive as hell. One cool aspect of the game - procedural graphics. The look and layout of the game's levels change every day. It keeps things interesting, and if you get stuck on a level you can put it down and try it again tomorrow - maybe with a little bit better luck when the boards have changed slightly.
Swipe Four I just downloaded this last night. It's like reverse Boggle. There's a free Lite version that allows you to play up to the first three levels. It didn't take long before I sprung for the full version which was only 99-cents.
