I would like to address this rumor as clearly as I can.
The app as it is right now- with full cloud based control- is, and will always be, free to use with our lights.
As far as premium features go- that's for new and advanced features only, like bluetooth control, intelligent acclimation, etc.
In addition you can own those features outright with a lifetime license.
We're a small business that made a big investment and put a lot on the line to introduce new features that we think our users will love. If you don't feel that the new premium features are worth it for you, you don't have to use them. We have a fully functional and easy to use free version, and that will never change.
Our app is already one of the best and easiest to use in the industry- and we will continue to improve and maintain the base features already included with our app at no additional cost to you.
