A private voice journal
Updated: September 7, 2026. Current App Store version: 0.0.28.
A voice journal is a journal you speak instead of write. You press record, say what is on your mind, and the app turns it into text. Most of them send your voice to a server to do that. Slate does not, and that is the whole point of this page.
What private means here
Your voice is recorded on your iPhone and stays there. Transcription runs on the phone with Apple’s SpeechAnalyzer. The reflection on each entry and the weekly review on Sunday are written on the phone by Apple Intelligence. There is no Slate server, so there is nothing to upload to, nothing to breach, and nothing we could hand over if asked.
The App Store privacy label for Slate reads Data Not Collected. Apple only allows that label when an app collects nothing at all.
What Slate does not have
No server. No account. No sign-up. No analytics. No tracking. No ads. No third-party SDKs. No network calls. The binary is Swift, SwiftUI, and Apple frameworks, and nothing else.
What it does have
Word-for-word transcripts. One reflection per entry, in your own words, that names what kept coming up. A weekly review every Sunday that reads the week back. Typed entries for the moments speaking does not fit. Six languages: English, German, Spanish, French, Portuguese, and Italian. Optional encrypted backup of transcripts and reflections to your own iCloud, off by default; audio stays on the phone even then.
The proof
Turn on airplane mode. Record an entry. Watch it transcribe, then watch the reflection appear. Everything still works because there is nothing to disconnect from.
Cost
One month free, then $7.99 a month or $59.99 a year, or $99.99 once for life. All through your Apple account. Slate never learns who you are.
