This app should do the trick https://www.space.com/totality-app-big-kid-science-april-total-solar-eclipse-2024 . I tested it on my Amazon Fire tablet and it gives you all the details for any point you tap on the map. You can zoom it up as close as you like. I have not been able to test the GPS functionality though as my tablet does not support it. You can also use this website which does pretty much the same (without the GPS). The times there seem to be given as UT by default, but you can toggle this with local time with the timezone tool button on the left.
Note that either of those require an internet connection though to download the maps (both of them use Google maps internally). Also, the second suggestion (and some others you can find on the web) is not optimized for mobile devices (the display is not very good and sluggish as well), so I would definitely go for the app, which runs quite smoothly.
