Necrometer

Review by eFreeware

Necrometer is a paid Android app from ChillSeekers, sold for $9.99 as a one-time purchase with no ads and no in-app purchases. It sits in the Lifestyle category but is built for a specific audience: ghost hunters and paranormal enthusiasts who want a single tool for investigating a location. The main reason to consider it is that it bundles three things that hobbyists usually cobble together from separate gadgets and apps: a magnetic energy meter, a text mode that produces words and phrases, and a speech mode that generates audible sounds.

The developer's premise is that spirits can influence magnetic fields and electronic devices, and that a phone's sensors can pick up those fluctuations. Whether that premise holds is something each user decides for themselves. What I can judge is the toolkit itself, and it is more elaborate than most apps in this niche. It has been on Google Play since May 25, 2023, and was last updated on October 22, 2025, so it is not an abandoned experiment.

What an investigation looks like with Necrometer

The app centers on a meter that reads magnetic energy using the phone's magnetometer sensor. According to the developer, spirits are believed to affect magnetic energy fields, and the app detects levels of magnetic interference in the environment. Those fluctuations are said to directly influence the communication, which is the thread that ties the three parts of the app together. There is also an optional meter noise that reacts to fluctuations, useful if you want an audible cue while your eyes are elsewhere.

In practice, a session seems to follow a simple loop. You move through a location with the app running, watch the meter for anomalies, and let the text or speech mode produce output that you interpret against what you are seeing and asking. The developer notes that the relevance of any communication depends on multiple factors, including spirit connection and strength, and that those with a stronger connection may get more direct results. That is a framing worth understanding before you buy: the app presents itself as a facilitator, not a guarantee.

Text mode and its word supply

Text mode is switched on by sliding the power control over, after which you ask questions and walk around the location. Words and phrases begin appearing on screen as the app registers energy anomalies and varying levels of magnetic interference. The developer says text mode draws on a pool of more than 60,000 words and phrases, which is a large enough supply that repetition should not become obvious in a single session.

The concept is compared by the developer to the Ovilus ITC device, a well-known piece of paranormal equipment that produces words in response to environmental readings. The app is pitched as a phone-based alternative built on the theory of random selection and reported cases of energy manipulation. For someone who has looked at dedicated ITC hardware and hesitated at the cost, this is the most direct appeal of the app: the same style of experience on a device you already carry.

Speech mode and the audio controls

Speech mode is the more unusual half. Sliding the power control the other way turns on audible output created to resemble ghost box and EVP-style communication. The developer is explicit that the speech sounds are generated from within the app, with no sound banks, word lists, radio or pre-recorded audio involved. The idea, rooted in ITC and EVP theory, is that spirits manipulate these random speech sounds into coherent messages.

Some messages are described as audible in real time, in the manner of a ghost box, while other EVP-like communication may only be noticed when you play back recorded audio. A rate slider lets you increase or decrease how quickly the audio comes through, which is the kind of control that matters when you are trying to follow a session. Clear messages require contact with a spirit; without that, only unclear speech sounds come through.

The audio side is rounded out with two built-in text-to-speech systems, three voices, pitch control with a randomization option, and reverb and echo effects. Taken together, these give you a fair amount of shaping over how the output sounds. I would expect tinkerers to spend a while adjusting voices and pitch before settling on a setup they like, while others will leave the defaults alone.

What the app needs from you

The meter depends on your phone's magnetometer, so the readings are only as good as that sensor and its surroundings. The app costs $9.99, so the decision rests on the screenshots. There are no ads and no in-app purchases, so the price is the whole cost of ownership.

The other consideration is the app's own framing. The developer ties the quality of communication to connection and strength, and says that unclear speech sounds are the expected result when no communication is taking place. Anyone hoping for a tool that delivers clear answers on demand should weigh that carefully. This is an app for people who enjoy the process of investigating and interpreting, not one that promises tidy results.

The ratings picture is worth a look as well. With a 3.5 average across 766 ratings and 50,000-plus installs, the reception is mixed rather than glowing. That is not unusual for this category, where expectations and experiences vary widely, but it is a signal that the app will not please everyone who tries it.

Who gets the most from it

The clearest fit is someone who already spends weekends at reportedly haunted sites and wants a phone-based kit instead of a bag of separate devices. The combination of a magnetic meter, a large word pool and generated speech audio covers the main activities of a typical investigation in one place. If you already know what an ITC session involves and enjoy the interpretive side of it, the app is built around exactly that.

It also suits the curious hobbyist who wants to experiment with spirit communication techniques without buying dedicated hardware. The text and speech modes are the draw here, and the audio controls give enough room to make the experience your own. What I would not expect is a casual user looking for a novelty to open once at a party. The app takes its subject seriously, and the price reflects that.

The case for paying for Necrometer

For a ghost hunter who would otherwise assemble this from several sources, that is a reasonable package, and the October 2025 update suggests the developer is still working on it.

The caveats are the ones the app itself sets out. The meter relies on your phone's magnetometer, the developer ties results to connection and strength, and unclear speech is described as the norm when no communication occurs. Add a 3.5 average rating, and the app asks for a bit of faith up front. If you are comfortable with that and the subject genuinely interests you, Necrometer is a well-equipped toolkit for the money. If you want guaranteed, clear answers, this is not the app that will provide them.
