Although we know a lot of the big Twitter clients out there will be going "Mango" soon, Mehdoh is a completely new Twitter client from developer Chris Field that is Mango-ready out the gate. The app is in the final approval stages for the Marketplace now, meaning it should be showing up any day now.
Mehdoh is a fairly impressive v1.0 client. Featuring background checks for mentions (every 30 minutes), Toast Notifications, flipping live tile (shows your profile pic, along with number of mentions) and adherence to the Metro design, we're quite impressed with this minimalist, yet highly functional app.
In addition to the above, it features a "report spam" selection, conversation view, super smooth scrolling, fast app resume, reTweet with comment and the ability to view web links and images inline with the Tweet--something that is highly useful.
The app does take a little while to update, mostly because it pre-downloads a lot of data, however Chris is looking to tweak this and we can expect it to change upon final release or soon thereafter. Mehdoh will fetch for $0.99 upon release with a free trial. A free, ad-supported version is planned, but not until a decent ad-service for Mango apps can be had in the UK. We recommend for the Mango users out there to give Mehdoh a look, as it's pretty sharp for a v1.0 release from an indy developer. Check out our video preview to get an idea of well it works.
