Free wireless Anki remote: how to use the iPhone you already have

What people actually want when they search "anki remote"

If you've been doing serious Anki review for any length of time, the search is predictable: you want to keep your hands free. Maybe you're walking on a treadmill, lying on your back at night, riding a stationary bike, or just sick of holding your phone the entire review session. You don't want to look at the keyboard. You want to flip the card and rate it without breaking flow.

For a long time, the best answer was hardware. A small Bluetooth keypad sits in your hand, you press a button, the desktop Anki app sees the keypress, the card flips. Done. That hardware-as-keyboard pattern is what made StudyRemote and the various 8BitDo setups popular in the medical-student Anki community.

What's changed: most people already carry a perfectly capable wireless remote in their pocket — their phone. We just needed software that turns it into one.

The existing options, briefly

StudyRemote (the dedicated hardware)

Originally a Kickstarter (then-named "Anki Remote"), StudyRemote is a small, wedge-shaped Bluetooth keypad with five chunky buttons. Plug it in, pair as a Bluetooth keyboard, and Anki sees its keystrokes (1, 2, 3, 4, space, undo). Around $40-60. They claim 30,000+ users; the product is real and works.

The case for hardware: tactile feedback, can't-miss-it dedicated buttons, no need to look at anything. For the strict "lying flat, lights off, no-look review" use case, dedicated hardware is honestly hard to beat.

The case against: it's another $60 device, another thing to lose, another battery to charge.

The 8BitDo workaround

Tiny gaming controllers from 8BitDo — most famously the Zero 2 and micro — have become a community favorite for Anki review. They're $20-30, fit in a pocket, and you can map face buttons to ease ratings. AnKing has a recommended setup; YouTube has a viral 80,000-view tutorial; Contanki is the de-facto Anki Desktop addon for it.

There's one big iOS-side asterisk that almost nobody talks about: AnkiMobile (the official iOS Anki app) won't accept those small 8BitDo controllers in gamepad mode. AnkiMobile only listens to Apple's GCExtendedGamepad profile, which the Zero 2 and micro don't expose. So the cheap, popular controllers people buy specifically for Anki work great on the desktop and don't work on the iPhone.

Contanki / Ankimote (Anki addons)

Both are excellent if you're staying inside the Anki Desktop ecosystem. Contanki especially is a polished addon — install it, plug in a controller, configure mappings. If you don't need an iPhone in the loop, this is a great free path.

The phone-as-remote option

This is what we built. Flashcard Guru Remote is a small Anki Desktop add-on (open source, LGPL-3.0) that pairs over Wi-Fi with the Flashcard Guru iOS app. The iPhone becomes the remote: you press Show Answer on screen, the desktop card flips. Press Good, the card schedules, you move on.

Two things make this not redundant with the existing options:

1. Free, with hardware you already own. If you have an iPhone, you don't need a $60 keypad to try this. (Whether you ultimately prefer hardware is a separate question — see the honest comparison below.)
2. You can bridge a cheap 8BitDo through the phone. Plug a Zero 2 or micro into your iPhone via USB-C/Lightning or pair it via Bluetooth. The Flashcard Guru iOS app listens for both Apple's GCExtendedGamepad profile and GCKeyboard events — which is what 8BitDo's "Keyboard Mode" produces. Press a button on the controller, the iPhone forwards the action to Anki Desktop. The exact controllers AnkiMobile rejects suddenly work, because the Flashcard Guru app is the one in the middle.

Setup (60 seconds)

1. On your Mac: open Anki, then Tools → Add-ons → Get Add-ons… and paste this code:

   1196082853

   Restart Anki. The first time the add-on starts, macOS asks "Allow incoming connections?" — click Allow.
2. On your iPhone: install Flashcard Guru from the App Store.
3. Pair: in Anki Desktop, choose Tools → Connect Phone (Flashcard Guru Remote)…. A QR code shows up. Open Flashcard Guru → Settings → Anki Remote → Pair with Mac and scan it. Done.

Open any deck on your Mac and the iPhone screen takes over. Show Answer, Again, Hard, Good, Easy, Replay audio, Undo — all of it. State updates flow back to the phone in real time, so the buttons that show up always match the card you're on.

Honest comparison

The honest verdict: if you do a lot of strict no-look review (treadmill, eyes closed, in the dark), dedicated hardware still wins because nothing beats tactile buttons under your thumb. If you do most of your review at a desk or sofa, with an iPhone within arm's reach already, the phone-as-remote covers 90% of the use case for 0% of the price — and if you also own a Zero 2, you can pair it to the phone and get the no-look ergonomics back as a bonus.

Why a phone instead of native Bluetooth keyboard emulation?

The obvious "wouldn't it be cleaner if the iPhone just was a Bluetooth keyboard the Mac saw?" question. The answer is platform-level: iOS does not allow third-party apps to act as Bluetooth HID peripherals. That's not a missing feature in any one app, it's a restriction Apple has held for a decade. So we use the next best thing — a small WebSocket connection over your existing Wi-Fi — which has the same end-user experience and the side benefit of supporting structured state updates (the iPhone always knows which deck you're in, which queue, which phase).

Privacy, briefly

The pairing token never leaves your local network. The add-on only accepts connections from RFC-1918 / loopback / link-local IPs as a safety check, so even if you accidentally exposed the port to the public internet, the server would reject the handshake. There's no analytics, no remote logging, no "phone home". You can revoke any paired iPhone from the Anki desktop dialog and the token is dead instantly.

• The AnkiWeb listing: code 1196082853

The iOS-side bridge is part of the Flashcard Guru iOS app, which is closed source. The add-on talks WebSocket — well-documented JSON protocol on the wire — so you could write your own client if you wanted to.
