About
Umbral is a spirit box for your phone that records the whole session.
A spirit box sweeps through fragments of sound so quickly that voice-like responses seem to surface from the noise. Investigators ask a question, wait, and listen. Umbral gives you that instrument, tuned to sound like real hardware, and then helps with what comes after: it captures the session, marks the moment something answered, and hands you a clip you can share.
EVERY SESSION RECORDED
Press start and Umbral records the full output mix automatically. No second device, no Voice Memos running on a friend's phone. Sessions are saved with date, duration and the location you name.
MARK THE MOMENT
Something answered? Hit MARK. A timestamp drops into the recording. Afterwards, every marker becomes a trimmable clip you can send to Messages, save to Files, or post, in a few taps.
A SWEEP THAT NEVER CUTS OFF
Set the sweep rate in milliseconds, forward or reverse, just like the hardware. Fragments always play to completion and overlap naturally. Slow the sweep down and you can actually hear what came through.
FOUR SOUND BANKS, BUILT FOR THIS APP
Wireline, Undertow, Backmask and Static: four banks with distinct characters and 1,650 fragments, built from public-domain voice recordings by 28 readers plus radio-style static, mastered for this app. Layer them, or run one at a time. Subtle random variation means the same sound never comes around twice the same way.
EFFECTS YOU CONTROL
Reverb and echo with wet/dry sliders, and a true DRY button that turns them fully off. Effects are subtle by default. Nothing is forced on you.
LOUD AND CLEAN
Mastered banks, a proper limiter and a master volume control. Plays over the silent switch. No clipping, no screeching, no straining to hear at full volume.
BUILT FOR THE RITUAL
A quiet room, a stated intention, short neutral questions, a pause after each one, ten to fifteen minutes, a deliberate close. Umbral's first-run guide walks you through it, and the app is designed around that structure.
ONE PRICE, EVERYTHING INCLUDED
No subscription. No ads. No unlocks. No account. Umbral works entirely offline, collects no data, and includes every feature and every sound bank.
Made by one developer who reads every review.
