this has been covered in many previous threads, but i read through a few, and i don’t think the answers i’m seeing are quite right. so i’m going to try to provide what i believe to be the correct answers here.
the Identifications webpage count and the count from the main page in the Android app are probably both counts of total (“identifications for others”) records in the identifications table, filtered slightly differently. the Android app’s total includes only current (not withdrawn) identifications, whereas the IDs page includes all identifications (including withdrawn).
(this should match the total on the Identifications webpage: https://jumear.github.io/stirfry/iNatAPIv1_identifications.html?per_page=100&own_observation=false&user_id=3133703¤t=any, and this should match the total in your Android app: https://jumear.github.io/stirfry/iNatAPIv1_identifications.html?per_page=100&own_observation=false&user_id=3133703.)
i’m not entirely sure how the identifications count in the profile is derived, but it’s an old page. so i wouldn’t be surprised if it’s doing something odd like keeping a running tally of your identifications, and adjusting for withdrawals, etc. i think the intent of the page is to report the same statistic that shows up in the Android app main page (current identifications), but if there’s a discrepancy between the two, i would tend to trust the Android app count because there have been known instances of inaccurate counts on the profile page (see https://forum.inaturalist.org/t/zero-observations-for-user-with-one-observation/4407/11).
