Tremo: Smart Baby Rattle

Tremo turns your iPhone (in a thick baby case) into a rattle that answers your baby's movement with sound. A light shake is a soft chime, a sharp one a bright beat, three in a row a little rhythm. The sound plays through a Bluetooth speaker across the room — the phone in your baby's hands stays dark and silent. WHY PARENTS LOVE IT • Cause and effect: at 5–14 months your baby discovers "I shook — something happened". A regular rattle has one sound forever. Tremo has dozens, and they respond to how hard, how fast and which way. • Seven sound sets that grow with your baby: Beads, Bells, Drops, Little drum, Xylophone, Animals (coming soon) — and My voice. • My voice: record "peekaboo" and your baby's name. The rattle answers with the voice they love most. • Under 60 ms from shake to sound on a good speaker. We measure your speaker's latency and tell you honestly. BUILT FOR SAFETY • The screen is black for the whole play. No pictures, no light, no touches. • Sound comes from a speaker, never from the phone near the face. A parent-set volume ceiling lives in the audio engine itself. • Play stops by itself: after 5 or 10 minutes, if the phone falls, gets hot, runs low on battery, loses the speaker, or lies still for a minute. • Exit is for grown-ups only: Guided Access, an Apple Watch button, or two fingers held in two corners. • Free: one play a day. Tremo+ has no cap, but suggests a break after three. Ten minutes per play is the limit for everyone. APPLE WATCH Your remote on the wrist: a timer, a gentle tap for every shake, and one End button. DIARY Every play is saved: minutes, shakes, rhythms, favourite sets — and a hint for each month, with the honest note that timing is individual. PRIVACY No analytics, no third-party SDKs, no account. Recordings and the diary never leave your device. WHAT YOU NEED An iPhone in a thick silicone baby case (any shockproof case will do), a Bluetooth speaker (recommended) and a parent nearby. Tremo is a toy for playing together, not for keeping a baby busy. Tremo+ is available as a monthly or yearly subscription (with a 7-day free trial) or a one-time lifetime purchase. Payment is charged to your Apple ID account; subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel in your Apple ID settings.
