Why we made TapStack.

You’re standing at the counter with the pill in your hand, and you can’t remember whether you already took today’s dose.

So you guess. Or you open the organizer to check, and the lids you didn’t mean to open come with it. The plastic ones spill in a bag, and they look like something you’d rather hide in a drawer than leave out.

We wanted a case you’re glad to carry: anodized aluminium, a lid for every dose that opens only when you press it, and a travel lock for the bag.

And we wanted the question answered for you. Tap your phone to the lid and the dose is logged with the time. No batteries, nothing to charge. The next time you wonder, you check your phone instead of guessing.
