How can I segment users based on the exact time (including minutes) they last opened the app?

By default, Pushwoosh records the 'Last Application Open' time with hour-level precision, and the segment builder using this default tag only allows filtering by days (e.g., 'Last Application Open was less than 1 day ago'). Segmentation based on the PW_ApplicationOpen event also requires a minimum time window of 1 day.

To segment users based on more precise timing, such as the last 15 minutes, you can implement the following workaround using a custom Tag:

1. Create a Custom Tag: In your Pushwoosh Control Panel, create a new Tag with the type DATE. Give it a descriptive name, for example, LastOpenTimestamp.
2. Update Tag from App: Modify your application's code. Using the Pushwoosh SDK's setTags method, update the value of your custom Tag (LastOpenTimestamp) with the current timestamp (including hours and minutes) every time the user opens the application.
   • Note: This requires development effort to integrate into your app's lifecycle events.
3. Create Segment: Now you can create a dynamic segment using this custom Tag. Set the condition to filter users where LastOpenTimestamp is within your desired recent timeframe.
   • For example, using the API or advanced segment builder features, you could filter for LastOpenTimestamp greater than or equal to the timestamp from 15 minutes ago (YYYY-MM-DD HH:MM:SS).

This method allows you to achieve minute-level granularity for segmenting users based on their last application open time.
