## What is Lock Tess?

Record your own voice as your car's lock sound, or choose from over 70 hand-picked sounds. 10 library sounds are free to try. Premium unlocks the full library, voice recording, and unlimited imports, plus iCloud sync across your devices. Lifetime unlock, no subscription, ever.

Lock Tess lets you customise your car's lock sound in seconds - all from your iPhone, iPad, or Mac.

Simply pick a sound from our built-in library, record your own, or import a file, then connect your USB drive to your iPhone, iPad, or Mac and tap Use. Lock Tess handles all the technical stuff automatically, creating the correctly named file your car needs. Plug the USB back into your glovebox USB port, enable USB as the sound in Boombox settings, and enjoy your new lock sound every time you walk away from your car.

--- SOUND LIBRARY ---
Over 70 hand-picked sounds ranging from funny to satisfying. Air horns, retro bleeps, dramatic stings, space missions, animal sounds, and more.

--- RECORD YOUR OWN ---
Say it yourself. Record straight into Lock Tess, watch the level as you go, and play it back before you keep it. Trim to the perfect moment and it's ready to use - no second app, no file converting, just you and your creativity.

--- IMPORT ANY SOUND ---
Found the perfect sound elsewhere? Import it! Lock Tess accepts MP3, WAV, M4A, AIFF, and FLAC files, automatically compressing, converting, and renaming to the exact format your car needs. Plus, for longer sounds, drag along the waveform to pick exactly which part you want to use.

--- ORGANISE YOUR SOUNDS ---
Store all your lock sounds in one place. Search, filter, rename, and categorise your sounds, mark your favourites for quick access, and share your sounds with friends via AirDrop, Messages, and more.

--- YOUR SOUNDS, EVERYWHERE ---
Lock Tess works beautifully on iPhone, iPad, and Mac. Unlock once and use everywhere. With iCloud Sync, your imported sounds automatically back up to iCloud and stay in sync across all your devices. Delete on one device and it disappears everywhere. Import on your iPhone and it appears on your Mac. Your sounds, always where you need them.

--- NO SUBSCRIPTION EVER ---
Lock Tess is free to try with 10 included sounds from the library. Unlock the full experience with a single payment. No monthly fees, no adverts, no subscriptions, no surprises.

--- HOW IT WORKS ---
Pick a sound from the library, record your own, or import a file

## Version history (last 5 releases)

### 2.0 — 2026-08-09

Lock Tess 2.0 is the biggest update yet: a completely new look, your own voice as a lock sound, and a real waveform trimmer.

RECORD YOUR OWN VOICE
Record straight into Lock Tess, watch the level as you go, and play it back before you keep it. Say anything you like and hear it every time you walk away from your car.

A WHOLE NEW LOOK
Every screen rebuilt from scratch. Darker, sharper, and easier to read at a glance.

REAL WAVEFORM TRIMMER
See the actual shape of your sound and drag along it to pick exactly the moment you want, instead of guessing where the good bit starts.

BETTER SOUND FROM YOUR CAR
Your car's lock speaker sits outdoors competing with traffic, so quiet sounds used to disappear in a car park. Every sound is now levelled to a consistent loudness, and the whole built-in library has been re-levelled to match. Plus trimmed edges get a gentle fade, so wherever you cut your sound there's no hard stop.

MORE RELIABLE ICLOUD SYNC
A full pass over syncing closed some bugs, so your library now travels between devices dependably.

ALSO FIXED
Recently Deleted now displays correctly on Mac
A rare crash when importing or deleting sounds
Clearer iCloud status messages in Settings
