Shine: It's a weather app that doesn't suck and is really pretty. Seriously! Shine is a beaut, when you bring it up, it gives the current weather in clear text with an enjoyable cartoon graphic. The bottom displays the forecast (which is side swipeable to see the rest of the 7 days) with high/low temperatures, precipitation and again, enjoyable cartoon graphic. It keeps things simple and to the point. Not for weather nerds, though. $1.
Oh, Ranger! ParkFinder: Oh, Ranger! has curated a list of parks where you can partake in twenty different outdoor activities. It's your virtual guide to the outdoors-you fire up the app, plug in your location (or let it locate you) and either see which parks are near you or find an activity you want to do to filter out the parks that let you do it. It's awesome. You can't run out of things to do or places to go with this app. Once you find the park you want, the app will give you a brief history about the place, activity descriptions, a phone number to call and directions courtesy of Google Maps. Free
CollabraCam: CollabraCam links video from multiple iPhones and feeds them into another iPhone that controls live, multi-cam editing. Utilizing a wireless LAN to get all the phones networked, the idea behind CollabraCam is that minimal-if any at all-post-production is necessary. $6
BoxyTunes: If you have a Dropbox account and use it to store music and podcasts, BoxyTunes makes it easy to grab those audio files on the go. BoxyTunes syncs up with your Dropbox account and lets you download music stored inside for playback on your iPhone or iPad. $2
RecognizeMe: RecognizeMe, a new jailbreak app, uses your iPhone 4's front-facing camera to scan your mug whenever you want to unlock your phone. Is it as discreet as tapping to enter? No-you probably couldn't subtly scan your face at dinner for some mid-meal texts. But it's surely a hell of a lot more secure, assuming you don't get sucked into some sort of Face/Off terrorism scenario. Jailbreak app.
Delivery.com: Because a few of us promote ordering takeout from our phones without having to talk to a human, here's a good one: Delivery.com's finally released an iPhone app. You already know if you need this. Like other similar services, you can order delivery, pickup, filter cuisines, order groceries, save favorite restaurants and all that good stuff that Delivery.com does. Free
PhotoForge2: PhotoForge2 might be a mere iPhone photo editor, but don't tell it that. For $3, you can adjust levels/white balance/colors, add effects filters, crop, resize, and embrace the power of LAYERS. Where you at, Photoshop? $3
Zaarly: It's like Craigslist but prettier and made for the iPhone. The app connects buyers who post what they want to buy and sellers who post what they want to sell. Obviously only works if people around you are using it. Free
