I've just launched my app Guitar Notes Master for Android. It's a guitar fretboard tutor that helps you learn note positions, chords, scales and arpeggios on the move. It was built with classic Xamarin using the MVVMCross framework as well as a number of Xamarin components such as InAppBilling and GooglePlayServices (not to mention Xam.Plugins.Settings, so thanks for that James!).
Hoping to start work on an iOS version as soon as my new Mac turns up
We hope to launch a Kickstarter campaign along the same time and if anyone want to help volunteer for a good cause in spreading the word, then please contact us.
I've published recently this small personal project. It's made with Xamarin.Forms, with the souce code public, and is currently available on Android and Windows Phone (iOS soon!):
A new social network, made with xamarin.forms (and a lot of custom renderers )

Excited to have just published Coffee Filter on iOS. It was already available on Android. Worked with some fellow Xamarins to port to iOS and of course it is completely open source on GitHub: https://github.com/jamesmontemagno/Coffee-Filter
Just released an early beta (0.2) of our ibGib app named...ibGib!
It's a pluggable learning app, currently with its first plugin: languageGib! It's an appGib that allows you to translate and review song lyrics from/to any language you want. We're polyglots, so this is how we're approaching expanding our vocabulary in Spanish, Italian, French, and German right now. But we're also programming geeks, so we've created a bunch of distributed architecture to do so in an efficient manner. Here is a quick screencast:
The songs make it genuinely fun (and effective as a mnemonic device), and this isn't just a sales angle either. They really do make a difference. E.g., most people know the song Frère Jacques...but if you use it to learn French, then you find out that the English translation actually hides the original humor of the song. "Morning bells are ringing!" actually more literally means "Ring the morning bells!", as the context is quite probably telling a Friar who has overslept to hurry up and ring the bells!
Anyway, I could go on and on, and this is only the first plugin for the app. You can find more at our website. We're working on others as well, including innovate features for languageGib too. Check it out and let us know!! (but remember it's beta LOL)
My company just released our first app using Xamarin. Its an iOS app that allows doctors to view patient information. We are planning on releasing to android later this year.

I have finally published my first app using Xamarin Forms. It was fun to write and I when exploring new features of Xamarin I will probably have another one ready soon. A bit of a challenge was to have a "nice" look on every device. As you can see I went with a darker theme on Android and a lighter theme on the iPhone, but all in one code base.
It is a "Don't break the chain" app to stick to or learn new habits. It was featured on lifehacker a long time ago and the idea is to make a check whenever you do something and create chain which you do not want to break when you once are not motivated.
I recently released Little Peanut on the Go, a mobile assistant for parents to help them stay organized and connected when they or their children are away from home. Parents can create packing lists and to-do lists, build care schedules to share with caregivers, and connect with their children with updates and photos while they’re away.
Parents can prepare for any outing by building packing lists and to-do lists. If they're leaving their children with a caregiver, they can create a care schedule that can be shared with the caregiver in the app. The caregiver will have access to the care schedule, plus emergency contacts, allergies, doctors, and medical facilities. While parents are away, they can connect with their children through updates and photos posted by the caregiver.
All of the handwritten lists and notes on the kitchen counter can be replaced with Little Peanut on the Go! Simply create the information once and share it with any caregiver at any time. As their children grow and change, parents can make a quick update and their caregivers will have the new information, right at their fingertips.
ZoneApp aims to connect people in a local and neighbourly way that strengthens communities in cities and neighbourhoods. Therefore ZoneApp serves cities, neighbourhoods, and university-campuses and many more places with its own newsfeed. Users can exchange information and will get the latest of what’s happening in their space.
We released few weeks ago our iOS app Ask PAM with Xamarin.iOS
Ask PAM is an on-demand personal travel assistance that connects directly frequent business Travellers to independent hotel Concierges. Like booking a taxi with Uber, frequent business travellers have direct access to local and personalized expertise thanks to a chat system. From finding the best places to eat, to booking an airport transfer or to take care of a situation that requires immediate assistance, an expert concierge from Ask PAM will always make sure you always get a personalized answer to your question.
Xamarin rocks! I created several iOS (iPhone and iPad) apps using Xamarin.Forms along with the MVVM pattern. The Xamarin.Forms ListView performance is outstanding. Below is the link to some apps:
Well, we put Yoga theme and game together and created Moksha, an iOS game. Currently only for iPads.
The objective of the game is to destroy the five enemies; Greed, Anger, Ego, Lust and Attachment as they appear in the game in the form of thought bubbles originating from the Yogi’s head. The player is required to destroy these thoughts with the help of three different types of stones (Earth, Water and Fire) and help the Yogi in attaining Moksha.
All done in C# + Xamarin + Sprite Kit. No previous game experience.
We made a "making of ..." video to show how we built an app from design concept, to mockup using sketch and the implementation in Visual Studio using Xamarin Forms.

Path of War blends action, strategy and MMO genres and features deep base-building mechanics and fast-paced tactical battles for an intense gameplay session every time players pick up their devices. With a 1:1 scale map of the United States functioning as the game board, Path of War offers a persistent massively multiplayer experience with player-vs-player (PVP) skirmishes. Each squadron begins at the Pacific Ocean and races their mobile base across the United States, battling for control of the nation.
Create A New Face app is intuitive and easy to use and most amazing app for real face changer in market.
Create funny faces from your photos, your friends' photos or celebrity pics.
1350+ beautiful high quality objects in various categories are available from true-to-life eye, glasses, mask, mustaches, hat, scar, mouth and much more!. Using this application you can do a complete face change.
Besides this give color adjustments to face items like brightness, contrast, saturation, gamma.
Create A New Face is easy. Really easy. The secret comes from its natural and intuitive design and the Auto Zoom ability to accurately position the objects to make the pics look real.
FEATURES :
1350+ high quality objects in 18 Different Category
(Animal,Comic, Crown, Earring, Eye, Glasses, Hair Man, Hair Woman, Hat, Mask, Mouth, Mustache, Necklace, Nose ,Scar ,Scarf, War Pack, Xmas)
Add speech bubbles to your photos! Selection of fonts, colors and bubble styles to choose from
Auto Zoom ability
Work with Layers
Layers reorder and lock ability
Color Adjustment for face items like brightness, contrast, saturation, gamma
Some insights of these applications worth to mention:
1.PCL approach applied
2.~65% of our project is reused by both platforms.
The formula is based on implementation complexity expressed as relation of development durations = “the estimated dev time of developing from scratch” DIVIDED BY “estimated dev time by reusing the existing project for one platform”.
3. What was unified:
- Database
- WebAPI
- Localization
- Network
- Multithreading
- Interscreen navigation
- Screens basic layout
- Business logic
4. We use hybrid approach (forms + native), to be exact:
native - when UI performance is crucial
forms - in all other cases
We had to rewrote couple of times the forms-based parts to native, due to their multiple performance and behavioral issues.
As result, we ended up with successful implementation of screen navigation and screens base layout on forms, while keeping platform specific implementation of UI elements (within those forms “skeleton” layouts).
5. Integrated some closed-source (non Xamarin) libraries as: Zendesk SDK, Braintree SDK, Google Conversion Tracking, others.
6. Our CI server is configured for automatized Xamarin apps building + running automation tests (based on in-house Calabash) with uploading resulting artifacts to the cloud platforms.
About the app
We wanted to create an app that could replace your address book. There are tons of locations worldwide that don't have actual street addresses etc. As a matter of fact, we have all been to places right here in the U.S. without proper addresses. So, instead of creating a regular contact and putting a note like "house is yellow and 16 yards from the oak tree", you can just add it to LifeProx!
Xamarin Forms Plug
Xamarin Forms was the best platform for us to use. There were some teething pains with some bugs (resolved by the Xamarin team over a few updates) but custom renderers came to the rescue perfectly when needed.
I absolutely love where Xamarin.Forms 2.2 is going! e.g. I would love to replace my custom render for a scroller with the newly announced CarouselView when it is released.
Time to wrap up our next app release and get that published too!
Can someone help me in finding i there is a possibility to read a business card / ID Card and store few of the fields in the database? If yes, Can you please share the code snippets.
I have checked in Xamarin Samples but it has a Credit Card Reader but not a regular business card reader.
We moved from Appcelerator to Xamarin after numerous performance issues and haven't looked back. We have built a secure messaging application for healthcare workers and patients. It's in the app stores now.
This was developed with Xamarin.Android. Nothing against native Java, but I loved being able to develop with good old C#. Would also love to port this to IOS, but not sure if IOS allows these types of interactive game wallpapers.
I've just released Kuklos Shooter for Android and UWP (soon iOS), it's a Bubble like shooter with physics. I've programmed it with CocosSharp 1.7 and Box2D 2.3.2

Well it's developed with Xamarin or I would not have posted it here.

Backend is written in C#, too. Some code is shared between the backend and the clients.
