## What is Continuous .NET C# and F# IDE?

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# 8 and F# 4.7 compilers so you can use the latest tech
>>> Xamarin.Forms Live XAML Editing
>>> 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.

## Key features

- Full C# 8 and F# 4.7 compilers
- Live XAML editing
- Automatic compiling and running
- Fancy text editor with inline errors

### 2/5 — Bug

*2025-09-14*

A nice app indeed, but due to the limited display space, it's only useful on the iPad. However, there's one problem: if you click the "I" button to save in the file manager, the program crashes, making the app unusable. You can copy the code and send it via email, but then you'll end up with a bunch of character formatting errors. Please fix this bug, please... :) iPadOS 18.6.2

### 5/5 — Very Useful IDE

*2025-08-26*

Working on the phone with any IDE can be difficult but this app does very well and it is at this writing close to the current C# version so it isn’t vaporware. Lagging one or two versions in my view is acceptable.

### 4/5 — C  version

*2025-04-23*

Description confirms v11 support, however, when I try to use v10 features, IDE says C# is only v9, and those features are not available. Otherwise it is a great tool for education.

### 1/5 — No custom delegates means useless.

*2024-05-17, version 1.5*

I guess you have to waste your money to find out you can’t have custom delegates. Maybe I am missing something but the code from Visual Studio doesn’t work unless you use EventHandler.

Useless. Money wasted.

### 5/5 — Update for iPadOS 17

*2023-10-14*

Very good app, but needs an update to run with newest iOS/iPadOS version. iOS 17 seems to completely remove the NewsstandKit framework. This is problematic for apps that happen to link with the NewsstandKit framework (they crash at launch).

Update:
Thank you for this update, now it works with iPadOS 17. Plus an upgrade to C# 11. This is my favorite coding app on my iPad.

### 1/5 — Doesn’t work anymore at all. Waste of money

*2023-10-04, version 1.4*

After exhaustive trying I can confirm this app doesn’t work anymore, at all, it crashes instantly on first load no matter how many times you reinstall it.

### 5/5 — Please Read (Dear Krueger Systems, Inc)

*2022-11-12, version 1.4*

/* I personally only review apps truthfully, and only if I believe that they really, REALLY deserve it. When I do, I try really hard to do them justice. This is the most effort I’ve ever put in. I spent a few days writing this review on and off throughout my first week of using this app and learning C# in order to properly convey how good it is. */

 

Genuinely wish there was a better way for me to show my respect than just 5 stars. It’s an incredible app that works flawlessly (My later gripes are just that, gripes, and aren’t functionality issues). The ability to code in C# OR F#, WITHOUT WIFI, ON AN IPAD! It even gives you the all the file types, templates, and the Console and IOS App options. I was shocked at how easy it was to follow along with C# tutorials taught on Visual Studios, even though I was using an iPad app, and I am so grateful for the different font options and dark mode. This is such a great thing to have. Worth the $20 if you want to learn C# or F#, code it on the go, or just like to have a portable option. 

 

Please know that I have my gripes (doesn’t everyone), but I’m sure that there’s hope for a remedy, so here goes:

 

A) The “Show Code Completion” Setting is annoying. 

It can be very frustrating when I type to declare a variable or class or something, hit ENTER to move to a new line, and then the Code Completion corrects my code to something I didn’t want instead. I am aware that there is a setting to turn off the Code Completion, and I’m not asking to remove it as an optional thing, however, every time I reopen the app after closing it, this is the only setting which doesn’t always stay how I left it. Regardless of how it was when I last closed the app, I can reopen Continuous any amount of time later (1 second, an hour, 12 hours) and it will be back in the on position, and I’d love it if you could fix that please.

 

B) The lines “KeyCode == Keys.——“  and “——_KeyDown(object sender, KeyEventArgs e)” (basically any key related code) don’t exist in the app as far as I can tell (And yes, this is when using the App.xaml.cs file type).

I understand that most users will not have a keyboard, but these lines should still be implemented in my opinion, as some do have a Bluetooth keyboard (myself included). It would also be nice if you could implement some kind of toggleable touchscreen keyboard/mouse under the watch window when fullscreened for those who don’t have a Bluetooth set.

 

C) I’d also love to see designated undo / redo buttons on the UI, as you can Ctrl + Z and   Ctrl + ^ + Z, but they work rarely, and sometimes you just make a costly mistake in one click that you want to undo.

 

I apologise if this review was insulting or seemed negative. It wasn’t intended to be. I genuinely love this app, am hopeful for its future, and would love to see my suggestions implemented. I respect you fully and wish you the best.

### 1/5 — Gets the job done I guess.

*2022-08-28, version 1.4*

Honestly the only reason I’m using this PAID app is because on the iPad c# IED’s are few and far between. This app really doesn’t take advantage of being on the iPad at all switching between your programs feels clunky, there’s no auto complete to any basic syntax, little to no customization to be found. If you have no other choice and are invested in c# then it’s useable, but if you can use visual studio or anything else I’d recommend that.

### 5/5 — Really good c  compiler

*2022-07-30, version 1.4*

This is one of the most well designed c# compiler on mobile system. I use my iPad editing coding for my project. It really support a decent amount of c# library and feature. Most important thing to me is it support OOP features on separate script(classes). Which is rare for a mobile compiler.

### 5/5 — Great but not amazing

*2022-06-06, version 1.4*

I love using this app whenever i feel like coding, but sometimes when i run the code (even without auto-run) it for some reason runs the same command multiple times. I can definitely see this app blowing up and becoming a great app for coding, it just needs some bug fixes. Things i could suggest are: fix the code running bug i previously mentioned, let the user delete text when typing into a readline console, make a debugger, and maybe some better explanations for how different functions work within the app. I still love using this, I just think it needs some work to be done.
