I haven’t explored those apps much, but rather left them installed for if I ever need the information. I also have ‘Medical Wikipedia’, ‘Sky Map’, ‘PlantNet’, and ‘Merlin’, but I don’t think I’d find much use with those in a survival situation. I would need to learn other skills first.
Not to hijack your post, but if anyone knows of other cool offline reference apps, that would be useful in a survival situation, it would be cool to know!
