Axon Anki Controller

The cheaper way into phone-free studying. A pocket Bluetooth controller, pre-mapped for AnkiDroid — flip your card with one button, grade it 1–4 with the others. No fiddly remapping setup; pair it to the phone you already have and review by feel: thumb on the buttons, eyes on the card, one hand. Tactile, eyes-up, one-handed reviewing. Upgrade to the full Axon Recall device whenever you're ready.
