For the past few months I've been working on a new iPhone app, which after a private beta period is now available in the iPhone App Store.

It's been quite a fun project, with lots of interesting technologies going into it. One thing I'm particularly pleased with is the rotation lock feature — you can see a movie of the lock wobbling below. But it also includes lots of other things, like a zoomable image view, integrated web browser and map view, and a custom theme. Lots of behind-the-scenes stuff, too, which I'll probably blog about later.

But for now, welcome to Tweeps, an iPhone OS app to easily manage Twitter accounts. Here's the main part of the product page, including a demo movie that shows most of the features. There's also a slideshow of screenshots available if you prefer that.

Check it out on the iPhone App Store! For a limited time, it's on special for just $0.99!

Tweeps is a Twitter companion app for iPhone and iPod touch, with an iPad-optimized edition coming soon. It isn't a full Twitter client — you can't post tweets from it. Instead, it is a tool to manage your Twitter account. Edit your avatar, name, bio text, website URL and location, plus follow/unfollow people, see if someone follows you, block people, and find people.

Add multiple accounts to Tweeps, and easily edit them:

• Take a photo or choose one from your photo library to change your avatar picture.
• Edit the name displayed for your account.
• Change the biographical text — the description you write about yourself.

• Edit the website URL, previewing it in an integrated web browser.
• Set your current location using the device's GPS, or type a less specific location, and preview on an integrated map view.

Learn all about your own accounts and others:

• See the display name, username, how long they've been using Twitter, and their Twitter ID.
• View the avatar picture, including full-sized, and copy it if desired.
• FOLLOW or UNFOLLOW other people. The left button indicates whether or not you already follow them.
• The right button indicates whether or not the displayed person follows you.
• Tap the right button to display a BLOCK button; you can also optionally report them as a spammer.

• Read the bio description text.
• See the website URL, and tap to display it in an integrated web browser.
• See the location, and tap to display it on an integrated map.
• Read the most recent tweet (update), along with the total number of tweets that have been posted; tap to read any number of recent tweets.
• See the number of people currently being followed (Following) and who follow the person (Followers); tap to list them and explore further.
• When viewing your own account, you can also see lists of tweets that mention you and people you're blocking.
• Find other Twitter people by username, first/last name, company, or brand name.

Read recent tweets from each person, or skim through the lists of people you're following and who follow you, and see more information about them, including who they follow and who follows them. A great way to discover interesting new people to follow — and you don't need to wonder if you already follow them or not, since it is shown right in the profile detail information.

Load newer updates simply by scrolling to the top, or automatically load more tweets or people by scrolling to the bottom.

A nice feature is rotation support — Tweeps works in all orientations, like an iPad, plus displays a fun wobbling rotation lock button to stop it rotating when you want to read lying on your side.

An edition of Tweeps optimized for the new iPad is in the works, and should be available soon after the iPad is released. Follow the Dejal Blog, or @dejal (main account) or @dejaltweeps (Tweeps account) on Twitter to learn when it is available.

Tweeps is available on the iPhone App Store for just $0.99 for a limited time (normally $1.99). Tweeps is not "abandonware". Dejal is a long-established independent Mac software company, now also producing iPad and iPhone software (which uses much the same Cocoa technology).
