Expert Controller Plus is currently in a testing project phase. It’s not yet ready for general public release as ‘working’ software but it does contain the majority of the features that will be in the production-ready, public release next year.
When a production-ready release is reached the plan is to make it available on this website and, just like Expert Controller, in the Apple App Store.
The first test phase started in December 2025 and is known as Alpha testing. During Alpha testing I hope to identify and resolve the features that just don’t work as they should. This will be followed by Beta testing when the App should be pretty stable and working with few defects. Once I’m happy that it is stable and pretty-much defect free, it will move into a production-ready, public release.
If you spot that something isn’t working or just doesn’t seem right, please do let me know as I can then investigate and resolve the issue. Please send all feedback using the Contact page.
