Ghost Radio: EVP Spirit Box

Review by eFreeware

If you already spend weekends poking around old buildings with a flashlight and a notebook, Ghost Radio is the sort of app you would want on your phone before you set off. It turns the handset into an EVP and spirit box tool, using the magnetometer and accelerometer to shape what you hear, and it keeps a record of each session so you can go back over it later. The developer, Exelerus Apps, has pitched it at hobbyists and small teams rather than at anyone wanting a toy to wave around at a party.

The appeal is the combination of a low price and a narrow, well-defined job. You pay $4.99 once, and there are no ads and no in-app purchases to think about. For that you get a tool built around sensors rather than a fixed library of words, plus recording and analysis features that make a session something you can revisit rather than just listen to in the moment.

What a session looks like

The core of the app is straightforward. A live EMF meter reads the phone's magnetometer, and a separate readout shows motion or vibration from the accelerometer. Those readings feed into the audio you hear, so the EVP output shifts with what the sensors pick up rather than cycling through a canned list of words. That distinction matters if you have used simpler spirit box apps and found the results repetitive.

Three visualizations are included for watching that output: an oscilloscope, a spectrogram and a voicegram. They give you different ways to look at the same signal, which is useful when you are trying to decide whether something in the audio is worth flagging. The developer describes the interface as night-ready, which fits the way these sessions usually happen, and there are guides inside the app for getting started.

Setup is presented as a roughly one-minute job, with beginner presets alongside more detailed controls. I would expect that balance to be the practical difference between this and a bare-bones spirit box: you can start quickly, then adjust once you know what you are listening for.

Recording, markers and comparison

Recording is where the app does more than most tools in this niche. You can capture a session, drop markers at points that interest you, and compare one session against another later. That turns the phone into something closer to a field log than a live gadget, and it is the feature I would value most if I were running regular investigations.

Recordings can be shared with friends or with a team, so a group working the same location can pass files around afterward. The app also attempts live transcription and saves the logs for review, which gives you a text record to skim alongside the audio. I would treat that transcript as a starting point rather than a finished document, since transcription of this kind of noisy audio is inherently approximate.

There is a noise engine with brown, red and white noise at several speeds, which gives you a way to set the background texture of a session rather than accepting whatever the app defaults to. Multi-language support is included as well, and help text sits on every screen, backed by an online knowledge base for anything the in-app guidance does not cover.

What it needs from you and your phone

The app runs entirely offline, with no account to create and no connection required. That is a real advantage in the kinds of places people take this sort of tool, where signal is often poor. It also means there is nothing to sign into when you want to start a session.

The trade-offs are mostly about scope. This is an EVP and spirit box tool built around a phone's sensors, so its usefulness depends on the hardware in your handset and on you having a method to fit it into. The developer is explicit that the app makes no scientific claims and cannot promise paranormal results, describing it as a tool to use within your own approach and to evaluate critically. It is labeled for entertainment purposes and carries an Everyone content rating.

The one-time price is the whole cost. There is no subscription, no advertising, and no in-app purchases, so nothing further is asked of you after the initial $4.99.

A tool for people who investigate in groups

The features point to a specific audience: people who treat this as a hobby with some structure, whether they work alone or as part of a small team. Markers, session comparison and sharing all assume you intend to review what you captured rather than just listen once and move on. If that matches how you approach an investigation, the app is built for you.

Beginners are catered for through the presets and the in-app guides, and the developer pitches the app as suitable for a first home investigation as well as a weekend at a location with a reputation. More experienced users get the deeper controls and the visualizations to work with. The 4.0 average across more than 6,200 ratings suggests a settled, widely used app rather than a novelty, and it has been available since October 2014, with the most recent update in September 2026.

A focused purchase for EVP hobbyists

Ghost Radio is worth the $4.99 if you want a phone-based EVP and spirit box tool that records what you did and lets you go back over it. The sensor-driven audio, the three visualizations and the marker and comparison tools are a coherent package for someone who already has a method and wants a device to serve it.

It is not a general-purpose paranormal kit, and the developer does not pretend otherwise: no scientific claims are made and results are not guaranteed, so it should be judged as an entertainment tool that organizes a session. If you investigate regularly, alone or with others, and you want your sessions logged and shareable without an account or a connection, this is a reasonable one-time buy.
