Dindy was very useful to me and (probably) to a few hundreds of people around the world. I enjoyed mainly reading the good reviews it got and getting supportive emails from users. But the reality is that since Android 5 Google has been making its own steps into the Do Not Disturb game, and even more so in the next version, Android M.
The changes in Android 5 already made Dindy less useful, by not allowing developers to put the phone in real silent mode. If you weren’t careful about who you select as a favorite contact, that would clash with Dindy’s settings. Android 5.0 specifically has bugs that prevent Dindy from working properly at all, and I had to apologize for that to a couple of users. These bugs were fixed in 5.1.
In Android M, Google basically implemented Dindy, with the exception of automatic SMS replies and some extra customizations that I doubt anyone was using. That doesn’t seem to be enough to justify an investment for users in an app to manage Do Not Disturb modes, or for me to keep adapting the app to Google’s changes in every Android release.
The first version of Dindy worked on Android 1.5 and I’ve changed it continuously to work with newer versions of Android over the years. Recently, in its peak usage, Dindy had around 1200 installations globally. That’s a very low number. My guess is that only a few hundreds of those were actually using it.
Unfortunately, Google still doesn’t get phone volume controls right. One thing that is very unclear is that if you want to switch the phone to vibrate, you should not lower the volume until it reaches vibrate mode. The result of doing that is lowering the phones ring volume to the minimum and then telling the phone that it should be on vibrate. If you have anyone important that you’d like to get past vibrate and ring, now your phone will ring in a very low volume. The correct way to switch to vibrate mode in stock Android 5+ is to click the volume button to see the volume controls and then tap the bell icon to switch to vibrate.
Apple got that right in the iPhone, by the way. Maybe Google will get it right in Android N.
