If your app has already has a cracked file for your target version available, you can't upload your IPA file. So now what?
Use the Crackulous app. Crackulous allows ordinary users to "crack" apps and submit them to AppTrackr. Other users can then download the IPA file onto their computer or directly to their device through the Installous app.
Very easy to get the warez. Also very tempting to just use the cracked app without buying it.
So you've built and installed your modified app on your device. Launch Crackulous on the device. You might not find your app there because Crackulous only lists apps that have been downloaded from the App Store.
So go download your app from the App Store.
Your app will now show up in Crackulous but it is not the version that your want to upload to AppTrackr. Build and install your app onto your device from Xcode. Do not delete the App Store originating app when installing the modified version.
The app is now shown in Crackulous. Go create a FileDude or Fileape account. Crackulous can automatically upload the cracked IPA to either of those services and submit the link to AppTrackr using what I assume to be the AppTrackr API.
Now enter your credentials into the Settings pane and crack your modified app. Submit to AppTrackr as prompted.
Now young pirateers and testing users can try out your app and be reminded that they can buy the app out of the App Store if they enjoy it.
So, you probably want to know whether this works. I'll show a bar graph for clicks over one month.
Half of the links from US with other countries taking up the other half. If you want to see updated numbers, go to the link's info page here.
35 more copies of Geometry Stash were brought in January than in December. I started using the link on 1/4. It's not possible to tell whether the increase in sales was from the modified version of the app or just a monthly fluctuation.
Apple should provide some App Store statistics for developers such as referral links and success rate per link in order for developers and companies to better market their apps.
