So, this is a question i asked my self many times.
How often should i update my apps?
is there a reason why i should upload a new build even if i don't update anything or make only minor upgrades to my app?
So from my experience it is indeed a good idea to update your apps regularly.
What i mean with regularly is every 1-2 month.
WHY?
Well, from my experience (and firebase stats) i have the filling that updated apps are somehow featured by the shops (google, apple) and it also make sense.
if you update your app regularly it means you use updated SDK's and this is exactly what apple, google wants. They always update their SDK and fix bugs so updated apps
will be featured by them to ensure people use their latest SDK.
i also noticed it that updated apps get more revenue in Admob and i guess it is because of using the latest Admob SDK.
So if you have apps that make you revenue and you have not updated them for a long time i recommend you to do that and it may also increase your income.
I have many apps and many of them i have even unpublished because they are stupid apps (junk) and i dont want to deal with them to much. i only concentrate on good apps that also make some revenue and i try to keep them up to date (<2 month old)
i made a simple Excel file where i have my apps listed and check the date they were last updated to keep track.
as you can see, i have some apps i will need to update. this is a short list of my best revenue apps for the last 30 days (from admob)
i will include the excel template file
(i use conditional formatting)
i hope it help someone.
have a nice day
