Heads-up before 1 day
A reminder before each charge, with a PAID button right on it.
Paid stamp Every bill
Each period gets stamped on its receipt; fix it any time.
Savings book Auto
Cancel what you no longer use and Bi adds up what you keep.
02 — The studio
Inspired by things everyone once held in their hands: a paper receipt, a roll of film, a yellow-digit LCD. Keep that touch and that texture, then set it on today’s technology.
Warm palettes, bold type and textures borrowed from paper receipts, vintage print and old-school devices.
Fast, accessible and native-smooth on iOS and Android — nostalgia without the old bugs.
Less, but better: every screen gets full attention, from the first sketch to the last pixel.
03 — Get in touch
Just write — every email is read and answered personally.
