Comments on P Numbers for Android

★★☆☆☆ Alex Rodriguez · Jun 5, 2026
Common Bug, this app performs just like the F Numbers App.... For some reason the app refreshes after making a selection and repopulates the default information... Constant fighting just to make a selection. I have tried to uninstall and reinstall the app but the same problem arises. I would like for C-spec to fix this bug
★★☆☆☆ Rob LeBlanc · Sep 18, 2024
Keeps resetting while trying to look at a value and goes back to top of page. Like the app but the resetting is annoying! Will give 5 star if you fix app.
