However, you can use the same code written on a Windows machine and build on a Mac if you want to target iOS.

No. You own your apps completely and any publishing arrangements are solely made between you and the different app stores.

Why does Corona require an Internet connection to build?

The Corona client requires an Internet connection to build because part of the build process happens on Corona Labs servers. The Lua script is precompiled into bytecode (stripping out comments, debug information, etc) before it gets sent to our server. The server embeds this data into the Corona engine, but never saves or archives it. By the end of the online build process, you will have an .app bundle or .apk file just as you would get if you had used the iOS or Android SDK yourself.

Back To Top

Does Corona Labs see my source code when I do a build? How secure is my project when it’s sent to your server?

No – during the online build process, our servers never see your raw source code — or for that matter any of your project images, sounds, or other assets. The Lua script is precompiled into bytecodes (stripping out comments, debug information, etc) before it gets sent to our server. The server embeds this data into the Corona engine, but never saves or archives it. By the end of the online build process, you will have an .app bundle or .apk file just as you would get if you had used the iOS or Android SDK yourself.

If I need offline builds, what are my options?

Corona Enterprise allows you to do offline builds. However, the Indie and Pro subscriptions of Corona require builds to touch our servers.

What is Corona Enterprise?

Corona Enterprise is a product, built on the same core Corona engine, that allows developers to call native libraries (Objective-C on iOS, Java on Android) from within their Corona projects.

Back To Top

How does Corona Enterprise work?

To build an app in Corona Enterprise you use Xcode (for iOS) and Eclipse (for Android) and compile the following elements:

  • Corona engine libraries
  • Lua project files
  • Native libraries
  • Lua bindings for your native libraries

Are Daily Builds stable?

Daily Builds incorporate the latest features or fixes added to Corona SDK. Because of this, it is possible that some instability could be introduced on any given Daily Build. However, our community is very good about finding new issues and pointing them out quickly. Any major issues introduced in a Daily Build will probably be fixed very quickly in a subsequent Daily Build.

Back To Top

Should I build my app using Daily Builds?

Many of our developers use daily builds for their day to day development. Since it is possible that Daily Builds can contain bugs, developers just need to be aware of this possibility and be ready to refer to the forums or other resources as necessary. We believe it is usually safe to develop against Daily Builds.

Back To Top

Where can I find Daily Builds?

If you are a Corona subscriber (Pro or higher), you will be able to browse and download Daily Builds here:

How many developers can use one Corona subscription?

One Corona subscription (Indie or Pro) can only be used by one (1) developer. Additional developers will require their own subscription.

Back To Top

On how many machines/computers can I use a Corona subscription?

Corona can be used by a subscriber on two (2) separate machines. However, each subscription is only meant for one (1) developer. Two machines are allowed so that developers can conveniently use Corona, for example on both their desktop and laptop.

Does Corona Labs take royalties on games or charge per title?

No. All our subscriptions are sold on a developer seat basis. Developers are free to build as many apps as they wish during the term of the subscription and we do not take any royalties or revenue share on apps.

Can I build iOS apps on a Windows machine?

Unfortunately no. Due to Apple restrictions you can only build an iOS app on a Mac. However, any code you develop with Corona on a Windows machine can be taken to a Mac and used to build your app. If you are unable to buy a Mac, we recommend using a service like MacinCloud (www.macincloud.com) to build your iOS apps.

What is a “session”?

A session is the period between starting and exiting an app by one of your users. Session data includes the start time, end time, a unique identifier for the user, and some information about the operating system and device.

Back To Top

How do I get started? What do I have to do to start seeing data?

To get started, just build your app with Corona SDK version 2011.591 or later using a Distribution Provisioning Profile for iOS or a Private Key for Android. Then get it into users hands to start seeing data. We take care of the rest!

Back To Top

Can I start seeing analytics data for an app I’m testing?

Yes. Just build your app with an Ad Hoc Distribution Provisioning Profile for iOS or a Private Key for Android. Then install the app on your test devices. If you don’t want to see data in analytics during test, build your app with a Provisioning Profile for iOS or a Debug Key for Android.

Back To Top

Is session data real-time?

Session data is processed and updated within a day. There is buffer for devices that do not have a connection to the Internet, which means you may see data appear later for users who weren’t connected while using your app but then connected later.

Back To Top

How do I remove an app?

Hover over an app in the left column navigation. You’ll see a red icon with an “x”. Click the icon. The app will be moved to a hidden list under “Removed Items”. To restore an item to the left column navigation, click “Removed Items” to expand the list. Hover over an app and click the green icon with the arrow. This will move it. Data is not removed when you move an app to “Removed Items”. It will still continue to be collected for any apps in “Removed Items”.

Back To Top

I don’t want data about my apps collected. How do I stop sending data to Corona SDK Analytics?

To stop data from being sent from your apps, just add “launchPad = false” to your config.lua file. This will stop the transmission of new data. Old data will remain in Corona SDK Analytics.
