As per topic title.
Looks like Notes and LEDison have updates available on Google Play.
Data actually has an update as well, but for some reason it doesn't show up as such unless you actually go to the application.
This was also communicated in their latest update on Indiegogo.
Now I have the version of LEDison that supports app-notifications, but it really doesn't do much, so GeminiLED is still a much better option for that: A single LED lighting up is much better than any blinking feature, that also has a time limit. For callers LEDison is useful, as it can display a unique pattern for each caller, or at least for the most common/important, as the call is coming in, but for notifications a single LED is better.
