Have you ever wanted to control your home with your wand? Well… now you can. Spellbook turns a movement of your hand into a spell; and a spell into your lights coming on. ---- HOW DOES IT WORK? ---- Two ways to cast: - Trace a spell's shape anywhere on your iPhone screen. - Or wear an Apple Watch and cast with a flick of your arm, phone still in your pocket. Eight spell patterns are recognised. Their shapes are drawn out for you in the spellbook. On Apple Watch, an enormous amount of recorded wrist motion has been fed into a machine-learning model that runs entirely on your wrist — accuracy is high and improving. ---- THE SPELLS ---- Lucernas — Upward chevron ∧ — Summon the light Obscura — Wave into a C — Banish it Repello — Right then down — Disarming force Subleva — U shape with a flick — The lifting charm Scutum — Straight line up — Raise your shield Amplora — Rightward chevron > — Amplify and enlarge Sistere — M shape — Halt all motion Aperio — Up then circle — Unlock and open Coming soon: Exanima and Mineura. The names are Latin, and every one of them can be renamed. If you'd rather say something else entirely when you summon the light, the spellbook is yours to write in. ---- WHAT HAPPENS WHEN A SPELL LANDS? ---- You decide. Bind any spell to an action, on iPhone or Watch. Cast the light-summoning spell and your bedroom lamp comes on. Cast its opposite and the room goes dark. Give each spell its own sound — your own recording, if you like — and optional haptic feedback so it answers in your hand. ---- WHAT CAN I CONTROL? ---- - HomeKit lights — any room, any scene, any brightness - Accessories — switches, plugs, fans, TVs - iPhone — media playback, torch, brightness, volume - Attunement (Apple Watch) — hold a spell and turn your wrist to slide brightness or colour, continuously - A cinematic reveal on iPhone as the spell lands ---- CAN I FINE-TUNE IT? ---- Everyone casts differently. Adjust onset sensitivity, gesture speed, confidence threshold and cooldown to match your style — precise and deliberate, or fast and snappy. Settings sync to your Watch instantly. ---- DUELLING ---- Battle a friend over a direct peer-to-peer connection — no Wi-Fi needed. Just be in range, and be quicker than they are. ---- FREE AND UNLOCKED ---- Spellbook is free to use, with seven casts a day. Unlock it once and cast as often as you like, plus actions, custom sounds, attunement and duelling. ---- PRIVACY ---- Everything runs on-device. No cloud processing. No account. ---- REQUIREMENTS ---- iPhone with iOS 18.6 or later. Tracing spells on screen needs nothing else. For wrist casting: Apple Watch Series 4 or later, watchOS 10 or later. Your wand awaits.

Verdict
The clearest difference is in-app purchases: BeyBuilder at none against Spellbook's 3. BeyBuilder also leads on update cadence (every 3 days vs every 10 days) and iOS requirement (15.6 vs 18.6). On price, ads and device support there is nothing between them.
