Where Kistvault is different

iOS and Android. Vaultaire is iOS-only; a Kistvault vault is one byte-exact container that opens on both. If anyone in your life is on Android, that's decisive.
Argon2id, not PBKDF2. Even at 600k iterations, PBKDF2 is friendlier to GPU/ASIC cracking than a memory-hard function. Kistvault's Argon2id raises the real cost per guess.
Truly local. Vaultaire offers encrypted iCloud backup (on by default, per our research); Kistvault has no cloud at all. Your backup is a container you export and place.
Recovery as a first-class path. A printed Recovery Kit plus device pairing is a broader recovery story than a single recovery phrase.
Nothing phoning home. With no backend, there's no analytics server — nothing on by default to switch off.

Where Vaultaire shines

Vaultaire is a genuinely polished iOS app with a sharp "hidden isn't encrypted" message, and it ships features Kistvault doesn't yet: a duress mode, a secure in-app camera, app-icon disguise, and secure sharing. If you're exclusively on iPhone and want those today, it's a strong, credible choice.

Bottom line: choose Vaultaire for a mature iOS-only experience with duress and in-app camera. Choose Kistvault if you need iOS and Android, memory-hard Argon2id, genuinely no cloud, and a printed Recovery Kit.
