Cool project, but the issue is rather that the US has pill bottles at all. Pretty scary, especially for overdoseable drugs. Other places have moved on blister packs a long time ago.
Personally, I use habit tracking app to check in every night to mark I took my pills.
Oh this drives me _nuts_. I ended up keeping a small Leatherman knife in the bathroom to slice through the paper/foil in the middle of the pack and peel the covering to each side.
(* and that if you're taking them as you go, you'll probably be physically incapable/less inclined to continue far enough after a certain point)
