2–3″ monochrome e‑paper
Crisp, paper‑like text that holds an image with zero power.
Concept — pre‑order open
Learn a language in the cracks of your day.
A solar e‑paper keychain that turns idle minutes — queues, commutes, the gym — into spaced‑repetition practice. No notifications. No feed. Just the next card.
Monochrome e‑paper · Purely solar, no battery · Waterproof
Your phone was never built to help you focus.
Open an app to study and you're one notification from the feed. Recall does one thing — it shows you the next word — and it lives on your keyring, so it's there the moment a spare minute appears.
- E‑paper is calm and easy on the eyes — no backlight, no glare.
- Solar power means you rarely think about charging.
- It can't ping, scroll or distract you. By design.
How it works
- 01
Pick your deck
Recall Solar ships with one built‑in deck, chosen at checkout. Solar+ and Master add Bluetooth loading — push Anki‑style decks straight from your phone.
- 02
Learn by spaced repetition
The proven interval method shows each card right when you're about to forget it. Maximum recall, minimum effort.
- 03
Sleep mode is yours
When idle, the screen shows whatever you like — a QR, your plate, a slogan, a phone number.
Designed down to the gram
Solar on the back
Tops itself up in daylight. The solar model only lets you study in good light — kinder to your eyes.
Bluetooth decks
Push decks from your phone in seconds. (Solar+ & Master)
Waterproof body
Sealed against rain, sweat and the bottom of your bag.
Hidden controls
Buttons tucked inside the shell — likely touch with haptic feedback.
Made for your hand
Left‑ or right‑handed layout. Black or white.
Words on the front. Sun on the back.
A monochrome e‑paper card you can read in any light — and a solar back that keeps it running. Purely solar, no battery, no charging cable.

Questions
Does it need charging?

Left or right handed?
