FAQ
Questions, answered.
The box
How big is it?
200 × 92 × 30 mm (about 7.9 × 3.6 × 1.2 in).
What is it made of?
Anodized aluminium.
How much does it hold?
A week: 14 compartments, AM and PM for every day.
Can I open just one compartment?
Yes. Press a lid and only that one pops up; the rest stay shut.
Will it open in my bag?
No. The travel lock keeps every lid shut until you slide it back.
How do I clean it?
Wipe it with a soft, damp cloth.
Tap to log
Does it need batteries or charging?
No. The badge in the lid is a passive NFC tag; your phone powers it for the moment you tap.
Which phones work?
Any phone with NFC: recent iPhones and most Android phones.
How do I log a dose?
Hold your phone to the badge on the lid. One tap logs it.
What gets logged?
The dose and the time you tapped, so your week is on your phone instead of in your head.
