Continuous is a fast and powerful .NET C# and F# IDE that runs directly on the iPad and iPhone (no network needed!). With it, you can write apps and games using your favorite languages on your favorite devices.

Continuous is always building and running your code so you can see changes as you type. Writing interactive apps in Continuous is a pleasure compared to the traditional code-build-run cycle. It frees you to make lots of small changes and see their effects immediately - no more waiting for builds or deployments and no more clicking around trying to get to the screen you're trying to code.

Continuous looks and works in many of the same ways as traditional .NET IDEs so you'll feel right at home, but it also strives to advance the state of the art in IDEs with these features:

>>> Full C# 6 and F# 4 compilers so you can use the latest tech
>>> Automatic compiling and running so you can focus on the code and the results
>>> Fancy text editor with tabs, semantic highlighting, inline error bubbles, and inline values that are updated as you type
>>> Watch window enables you to view graphical objects in your app (UI and images), inspect live objects as your app runs, create instances of new objects, and call methods
>>> Code completion with inline type info and documentation makes learning new APIs fun
>>> Uses standard .NET file and project formats so you can share code with other IDEs
>>> Includes Xamarin.Forms and UIKit to build apps and SpriteKit and SceneKit to build games. You can access many iOS APIs including CoreMotion, the Social framework, and HealthKit to read data.
>>> Split screen support so you can keep documentation by your side
>>> Execution powered by a new IL interpreter

If you're new to .NET or iOS coding, you will love the code completion with integrated documentation and the fun examples that come with the app.

If you're a .NET pro, then you will love the support for projects and the ability to inspect objects as you code them - whether they're in a script or just a normal project file.

If you're new to programming, C# is an great language to learn: it's powerful yet friendly language, example code is all over the internet, and there are plenty of jobs out there waiting for you.

If you enjoy thinking a little differently, then you will love that F# is included and fully supported. This amazing programming language will teach you to write better code and will arm you to solve problems that you thought were too big or hard to solve - like writing an IDE.

Line numbers and Git

Please add line numbers and git integration. Also wen you move out of a field enable auto-formatting so that the formatting occurs when tabbing or moving away from the line. That’s all I think is needed for this app to be perfect.

Fabulous tool, well on its way to greatness!!

I was just made aware of this tool yesterday while listening to Scott Hanselman's podcast ("Hanselminutes") where Scott interviewed Frank Krueger the creator of this app. I was really impressed by Frank's approach to the challenges inherent in creating an IDE of this sort and the IL interpreter, and mods to his Roselyn fork.
More over, I really was pleased to hear Frank's vision of where this tool should go. He wants a built-in GIT repo client, but that might be more of an Apple attorney based (AAB) limitation. Frank also spoke about his desire to continuously improve the execution speed and dedication to the continuous debugger as well as source file integration is top priority.
Frank really pulled off some great architectural mojo with this tool.
Based on the quality of, and developer dedication to his other tools I've used - namely, "Calca" & "iCircuit" - I'm sure this app will continue to get more impressive as hurdles are cleared and his interaction with the Xamarin team increases. Keep up the excellent work Frank! What a helpful tool this is!!

Great IDE for offline mobile dev

I love playing around with Continuous when I have some spare time on the bus or in the pub. Quite powerful considering it compiles on iOS offline. It has its bugs and some workflows that took getting used to, but that didn’t stop me from prototyping 3 different games completely on my iPhone 6. If you love developing no matter where you are or how big your keyboard is, this is a solid app and IDE. Only wish there was better documentation and support. Supposed to be able to import my own libraries, but I haven’t been able to in my 1.5f years using it. Also would love to see the ability to import files or view the file structure in the files on iOS (to import sprites) Thank you developers of this IDE. I’ve used it tons.
