Can you double check that's the right report suite? "0 of 0" means that there's no data in that report suite for the last 90 days. If it was an issue with the segment definition, it would say "0 of 1000" or "0 of 43,000,000" or however big your data set is.
Love the logic, however, I can't even save this as a segment. My 90 day sample box also yields 0. I tried adding it into containers, taking it out of containers, etc. but no luck. Any thoughts as to why? Thanks!
i‘m not sure you can do that „the normal way“ since the question is a) at visitor level and b) need the information looking back...
i can think of the following idea: why don‘t you create a virtual report suite with custom settings for „context-aware sessions“? i would create one with visit definition of say 12 hours, trying to capture all visits of one day (this settings would capture alle hits within 12 hours as 1 visit). doing that, you have an approxiamte count of „days“ where users used the app, and can divide “visits“ it by total days to get an average frequency. not quite what you looked for but best what i can think. maybe play around with the time frame until it matches best for your case.
What about unique visitor metric? It wont allow you to see one specific user but it would allow you to see the sum of unique visitors (some duplication as users on multiple devices are counted multiple times then)
Bear in mind Adobe analytics is a aggregate level type of data collector. The "if a user used an app on day 2,5,17,23 of a given month" would then require the specific user to be identified(tagged) on each visit. Do you have user IDs that are assigned to users in a logged in state? if so then you could do a report by each user or pull a daily report by user ids. This will not help you for non logged in users though. There is a marketing ID in the latest DTM implementation but it is a cookie level identifier of all traffic visitors. it doesnt de-duplicate users who access via multiple devices as an example. Not sure if its available in iOS/android environment.
That just gives intervals between sessions and it's at the visit level.
I want to see by day; if you used the app one day in January, 2 days in February, and then another day in August. I don't care how many times within that day you've launched or used the app. Just trying to get overall usage over time at at the visitor level.
