Learn a language in the cracks of your day.
Recall is a 2.9-inch monochrome e-paper keychain for focused spaced-repetition practice. Recall Solar has no battery and runs only on solar power; Solar+ and Recall Solar Master store solar energy in supercapacitors.
2.9″ e-paper · Approx. 6 mm thick · Water-resistant design; final IP rating pending
Your phone was never built to help you focus.
Open a study app and the rest of your phone is one tap away. Recall is designed for one task: showing the next card whenever a spare minute appears.
- A paper-like display without a bright phone screen.
- No feed, notifications or unrelated apps.
- Three power configurations for different use conditions.
How it works
- 01
Choose one deck
When sales open, one available deck will be selected at purchase and programmed onto the device. Anki deck import is not supported in the current version.
- 02
Review with spaced repetition
Cards return at increasing intervals as you remember them, keeping each session focused on material that needs more practice.
- 03
Use spare moments
Review a few cards in a queue, on a commute or between other tasks without opening your phone.
Current hardware concept
Approximately 6 mm thick
The current enclosure is designed to be about 6 mm thick; final production dimensions may vary.
Water-resistant design
Water resistance is a key design requirement. The final IP rating has not yet been confirmed.
Recall Solar: solar power only
No battery or stored charge: the device runs directly from the solar panel and requires sufficient light to operate.
Solar+ and Solar Master: supercapacitors
Solar+ stores energy in a smaller supercapacitor; Recall Solar Master uses a larger one. Exact capacity and runtime are still being defined.
Deck options by model
Recall Solar is planned with one deck programmed at purchase. Bluetooth loading of custom decks is planned for Solar+ and Solar Master, but the workflow and file format are still in development. Direct Anki import is not supported.
Words on the front. Sun on the back.
The current concept pairs a 2.9-inch monochrome e-paper display on the front with a solar panel on the back. The enclosure is designed with water resistance in mind, but its final IP rating has not yet been confirmed.

Questions
Can I order Recall now?
Not yet. Recall is in development and available through the waitlist only. Joining is free and does not place an order or reserve a unit.
How are the three models powered?
Recall Solar has no battery or stored charge and runs directly from solar input. Solar+ and Recall Solar Master store solar energy in supercapacitors; Solar Master uses the larger capacity. Exact capacities and runtime are not yet confirmed.
Is Recall waterproof?
Recall is being designed for water resistance, but the final IP rating has not yet been confirmed. No specific protection level should be assumed until testing is complete.
What are its dimensions?
The current design uses a 2.9-inch display and is approximately 6 mm thick. Final production dimensions and weight may vary.
Can I import Anki decks?
Direct Anki deck import is not supported. Recall Solar is planned with one available deck selected at purchase and programmed onto the device. Bluetooth loading of custom decks is planned for Solar+ and Solar Master, but the workflow, supported format and final deck list are still being defined.
When will it ship, and what warranty will it have?
Shipping regions, costs, taxes, delivery timing, returns and warranty terms have not yet been confirmed. They will be defined before orders open.
