Spirit Talker ®

Review by eFreeware

Spirit Talker takes an unusual premise and commits to it: the app watches your phone's built-in sensors and turns what they register into words, on the theory that a spirit could nudge those sensors to spell something out. It is a paid download at $5.49, with no ads and no in-app purchases attached. That combination alone sets it apart.

The developer, Spotted: Ghosts, describes the app as working along the lines of an Ovilus device, a piece of dedicated ghost-hunting hardware, but built on the studio's own research and theories. That framing tells you most of what you need to know about the audience. This is for people who already take paranormal investigating seriously enough to want a tool rather than a novelty, and who are comfortable with the idea that the results depend on interpretation as much as on the hardware.

It has been downloaded more than 100,000 times and holds a 4.3 average across 5,907 ratings. The app first appeared in October 2020 and was most recently updated in September 2026, so the developer is still tending to it years later.

What the sensors actually do

The core of the app is a set of readings pulled from hardware your phone already carries. The magnetometer picks up electromagnetic fluctuations, the accelerometer measures movement and vibration, the gyroscope tracks orientation and rotation, and a gravity sensor monitors gravitational changes. On top of those, the app also draws on humidity, ambient temperature and air pressure where the device can report them.

According to the developer, the sensors are meant to pick up influence from spirits, which then shapes words and phrases, and every response comes from real sensor readings instead of random selection. That distinction matters to the intended user. Whether you accept the underlying theory is a separate question, and the app's own disclaimer is candid that the paranormal is a theoretical field.

One practical detail worth flagging: the magnetometer element only works on devices that actually have one. Not every phone does, so checking your handset's specifications before buying is a sensible step if EMF readings are the part you care about most.

Running a session from start to finish

A session follows a simple loop. You tap start, ask your questions aloud, and wait for words to appear on screen, where they are also spoken out. When you are finished, you tap stop and the responses from that session are saved. Past messages can be revisited through a folder icon, though the developer notes that this only works while the scanner is stopped, so reviewing old sessions is something you do between investigations rather than during one.

If your device is not vocalizing the responses, the fix is to install Google Text-to-Speech and set it as your preferred voice engine under the accessibility settings. The developer also suggests switching to it if the built-in voice sounds robotic, which is a reasonable nudge for anyone who wants the session to feel less mechanical.

Fast movement or nearby electronics can skew the readings, so keep the phone still and away from other devices.

Languages and where the app travels well

Spirit Talker covers a wide spread of languages: English, French, German, Danish, Portuguese, Romanian, Turkish, Croatian, Polish, Finnish, Swedish, Hungarian, Greek, Czech, Dutch, Italian, Spanish and Icelandic, plus Latin and Chinese in either text or symbols. The developer says more will be added over time.

That range is more useful than it first appears. Paranormal investigating is often a group activity, and teams are not always made up of people who share a first language. Being able to run a session in the language your group actually speaks, or to switch to Latin or symbol-based Chinese for a specific experiment, gives the app more flexibility than a single-language tool would.

Someone investigating a site in Poland or Finland can work in the local language rather than translating whatever appears on screen afterward, which keeps the session itself intact.

Setting up before your first session

There is not much to configure. You install the app, confirm that your device has the sensors you want to use, and make sure Google Text-to-Speech is present and selected as the voice engine if you want responses spoken out loud. The developer links directly to Google Text-to-Speech for anyone who needs to add it, and walks through the accessibility menu path for changing the voice.

The magnetometer check is the one step that can catch people out. If your phone lacks that sensor, the EMF side of the app will not function, even though the accelerometer, gyroscope and environmental readings may still work. Reading your device's specifications first avoids that disappointment.

Beyond that, the setup is about the room rather than the phone. Find a surface that will hold the device steady, keep it clear of other electronics, and resist the urge to pick it up mid-session. The developer's guidance on interference is worth following.

Who this fits

The clearest fit is someone who already investigates the paranormal and wants a phone-based tool that behaves like a dedicated device. If you have looked at Ovilus-style hardware and balked at the price or the bulk, this is a $5.49 app that runs on something you already carry. The absence of ads and in-app purchases matters here too.

It also suits people who want to try the same tool at home. The app gives them a straightforward way to run sessions without buying extra equipment.

The Teen content rating is worth noting for anyone considering it for a younger household member. And the disclaimer is explicit that words generated should not be treated as commands or as advice for legal, financial, medical or life decisions, which is a sensible boundary for a tool built around interpretation. It is quiet, sensor-driven and dependent on how much you bring to it.

A focused tool for serious hobbyists

Spirit Talker does one job. It reads your phone's sensors, turns changes into words, speaks them aloud and keeps a record of each session.

The caveats are real but manageable. You need a device with the relevant sensors, the magnetometer in particular, and you need Google Text-to-Speech installed for spoken responses. None of that is unreasonable for the intended user, but it does mean the app rewards a bit of preparation.

Go in understanding that the app supplies the readings; what they mean is down to you.
