Had a really good conversation tonight that made me feel...
It reminded me that intimacy is often just being understood in small precise ways. Not grand gestures, not dramatic confessions. Just someone catching the exact shape of what you mean. I left feeling calmer than I’ve felt in a while....

I’m noticing how much my energy changes depending on whether I start the day online...
If I open my phone too early, the whole day gets fragmented. My attention becomes public before it ever becomes mine. But when I protect the first hour, I think more clearly and I feel more like myself. That pattern is getting too obvious to ignore.

I don’t think I’m burnt out exactly, but I do think I’m emotionally overclocked...
Everything feels slightly too loud lately — expectations, decisions, notifications, plans. Even good things feel like input. I think I need fewer tabs open in my mind. Not a full reset, just less cognitive clutter..

I’m proud of myself for not spiraling after that awkward interaction...
Old me would have replayed it for hours and assigned it all kinds of meaning. Today I just noticed the discomfort, let it exist, and kept moving. That actually feels like progress. Small, but real...

Your most honest thoughts deserve a private place to land.

Undertone; an offline voice journal built for clarity, not surveillance

Features

Everything you need.
Nothing you don't.

Undertone is built around one principle: your voice journal should be yours - offline, honest, and beautiful.

🔒
Truly offline

Transcription runs entirely on-device using Whisper AI. No server ever touches your audio or text; not even ours.

🎙
High-fidelity transcription

Powered by OpenAI Whisper (Large, Medium, Small); the same model that powers professional transcription, running silently on your iPhone.

📓
Minimal, beautiful design

A calm, distraction-free interface. Writing and reading feel like turning pages, not staring at a dashboard.

🏷
Tags & search

Organise entries with custom tags and search across everything: your full library, fully searchable, entirely local.

🔊
Playback with waveform

Replay any recording alongside its transcript. A gentle waveform shows your audio's shape and lets you scrub precisely.

💾
Backup & restore

Export and restore your entire journal archive. You own your data and you can always take it with you.

Privacy isn't a setting. It's the foundation.

Many apps claiming "on-device" transcription quietly route your audio through Apple's Speech servers. Undertone bundles Whisper models locally for you.
