Frequently Asked Questions
Looking for answers to questions related to Corona? This is a great place to start.
What does it mean that Corona SDK is now free?
It means that anyone can now use Corona SDK for free. This includes ALL the features that were previously available at the highest tier (Pro). Just download the Corona Simulator and you will have access to all the functionality. If you were previously a Starter or Basic user, just log out and log back in and you should be set.
What features are included in the free Corona SDK?
All of them. Everything that was included in Corona SDK Pro is now in Corona SDK (notice there are no tiers anymore – it is just “Corona SDK”).
Are Corona Enterprise and CoronaCards also free?
Corona Enterprise, CoronaCards iOS and CoronaCards Android are still paid products.
Corona Enterprise lets Corona developers call any native library from their Corona projects. CoronaCards let’s developers embed Corona functionality into any native app.
I was a paid user of Corona SDK (Basic, Pro or Enterprise) on March 1. What does Corona SDK going free mean for me?
We want to make sure all our users are satisfied with Corona and with their purchases. So we are going to upgrade ALL our current subscribers as follows:
- Current Corona Enterprise customers get CoronaCards iOS and CoronaCards Android licenses (1 month for each month you have left) for free.
- Current Corona SDK Pro customers have been upgraded to Corona Enterprise (1.5 months for each month you have left) and will also get CoronaCards iOS/Android for free.
- Current Basic customers have been upgraded to Corona Enterprise (1 month for each month you have left) and will also get CoronaCards iOS/Android for free.
I was a Corona SDK Basic or Pro subscriber and I have no use for Corona Enterprise. I want my money back! What do I do?
Clearly we can’t refund everyone that has bought Corona in the last year. However, we do want to make sure recent purchasers do not feel cheated. If you do NOT want to take advantage of the free upgrades to subscribers AND you purchased Corona SDK Basic/Pro in 2015 (i.e., on or after January 1, 2015), you are eligible for a refund.
Simply email us at firstname.lastname@example.org and tell us you want a refund (and the email address for your Corona account), and we will issue a pro-rated refund for your purchase.
PLEASE NOTE: you have to email us BEFORE end of day on March 15 (PST) to be eligible.
How do I get access to Corona SDK?
You can download Corona SDK here. Once you download, you can immediately start building an app or game. We do not provide disks or any other physical media.
What platforms does Corona run on?
The Corona Simulator is available for Mac OS X or Windows. Please note that, because of Apple restrictions, you cannot build apps for iOS using the Windows version of the Simulator. However, you can use the same code written on a Windows machine and build on a Mac if you want to target iOS.
What platforms can I build apps for?
Corona currently supports building apps for the following platforms:
- Windows Phone 8
- coming soon: Mac OS X and Windows!
What is Corona Enterprise?
Corona Enterprise is built on the same core Corona engine and allows developers to call native libraries (Objective-C on iOS, Java on Android) and APIs from their Corona projects.
How does Corona Enterprise work?
To build an app in Corona Enterprise you use Xcode (for iOS) or the Android SDK and compile the following elements:
- Corona engine libraries
- Lua project files
- Native libraries
- Lua bindings for your native libraries
How much does Corona Enterprise cost?
Please see our pricing page for more information.
Why does Corona require an Internet connection to build?
The Corona Simulator 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.
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.
How do I file a bug?
Please file bugs using our bug submission form. Please note that, in order to facilitate us isolating and verifying a bug, we request you submit a simple test case demonstrating the bug. We cannot evaluate test cases that include code from third party products.
Who do I call if I have a problem?
Do you have educational discounts?
Yes. We have discounts for students and educators buying 1-2 licenses. We also have Academic Site Licenses for institutions looking to buy more licenses. You can read more about our educational options here.
Does Corona Labs publish my apps?
No. You build your apps with Corona, but you will take your app’s files and publish them directly on the app store providers’ sites using their developer programs.
Does Corona Labs take any revenue share of my apps?
No. You own your apps completely and any publishing arrangements are solely made between you and the different app stores.
Can I get a refund for my Corona license?
We can only refund licenses within 5 business days of a purchase. If for some reason you decide you want a refund, make sure to let us know within that time frame. We will charge a 10% refund fee to cover payment processing fees.
Does Corona Labs offer support?
Corona developers can get community support through our forum. The Corona community is very helpful and frequently answers questions as they come in. In addition, Corona Labs keeps a presence on the forums and answers questions on a best-efforts basis.
Corona Labs also offers paid support. We offer Premium Support for customers that require any of the following services:
- Code Examples
- App Debugging
- Code Review
For pricing and more information go to our Support page.
Does Corona Labs offer training?
Yes. We offer basic one-on-one training for developers looking to get up and running with Corona. For more information, please see our Support and Training page.
How can I find a Corona developer?
Corona doesn’t yet support a feature I need. What are my options?
We are working hard to add new features to Corona every week. If we do not yet support a feature you need, Corona Enterprise allows you to call native libraries from within Corona projects.
If I use Corona, do I need to pay for the Apple or Google developer programs?
Yes. When you submit and publish your apps to the iTunes App Store, Google Play, or any of the other stores you will need to join and pay for their respective developer programs.
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.
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 for Daily Builds to 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.
Where can I find Daily Builds?
You can download Daily Builds here:
How many developers can use one Corona license?
A Corona license can only be used by one (1) developer. Additional developers will require their own license.
On how many machines/computers can I use a Corona license?
Corona can be used by a developer 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. Corona SDK is free to use. Corona Enterprise licenses are sold on a developer seat basis. Developers are free to build as many apps as they wish Corona and we do not take any royalties or revenue share on apps.
Can I transfer my license to a third party?
No. Licensees are not allowed to sell or transfer their license to parties outside their own company/organization.
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.
