I was one of the close voters.
- You were specifically seeking for an app, which is discouraged for reasons mentioned and reproduced
Questions asking us to find or recommend an app, device, ROM, accessory or off-site resource are off-topic for Android Enthusiasts as they tend to attract opinionated answers and spam and become obsolete quickly
Asking for a way or means to achieve your aim, is broader and covers all approaches to solve ( apps inclusive but barring programming / ROM modding, etc) .
If the intent of OP is to specifically seek an app based solution, then SE Softwarerecs is the right place. Here it is about posing a problem and asking for solutions, and those who respond may well offer app based solution or something in addition to app . See this question for example. It was also voted for closure but edited by me to make it a non app seeking question and answered . OP now has a method to help him involving a hybrid approach of using an app and other means resulting in a win - win outcome for the OP and the site
There are older questions on the site, which seek apps specifically and have not been closed. My guess is that these pre-date the current policy
Edit: To sum up , questions on this site are liable to be closed if they specifically seek app based solutions, whereas solutions can include app based approach
