You can, but it takes a few steps. I don’t have an iPhone but here’s how it works for Android:
- Go to Explore
- Select the Filters icon in the upper right
- Check Show Only My Observations
- Scroll down and change Sort By to Date Observed
- Select Apply Filters
- If desired, select the search icon and select the X next to My Location to see observations not seen nearby your current location
I wish these filters could be applied without needing to go through Explore, but that would require a feature request I suppose. It’s the same issue for searching for species you’ve seen that don’t match an exact genus/species name.
