Spectrolite vs Paranormal Beeper
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Spectrolite
This app visualizes sound in real-time using various spectrogram types. Explore detailed audio data with intuitive touch controls and adjustable parameters. An optional purchase unlocks advanced measurement tools.
- Real-time spectrogram visualization
- Constant-Q, linear, and mel frequency scales
- Full human hearing frequency range
- Intuitive touch panning and zooming
- Adjustable gain, Q, and other parameters
- Pro version: grids, scales, spectrum view, tap-to-measure

Spectrolite visualizes sound as spectrograms in real time. Spectrolite supports constant-Q spectrograms, which use a logarithmic frequency scale for a display where musical notes are evenly spaced. Spectrograms based on linear and mel frequency scales are also supported. The display covers the full frequency range of human hearing. Intuitive touch panning and zooming lets you dive in and explore the spectrograms in detail. Gain, Q, and other parameters can be adjusted in real time and instantly apply to the display of past signals as well as future ones. The Pro in-app purchase adds grids and scales for time, frequency, and amplitude, as well as a spectrum view and a tap-to-measure function. This expands Spectrolite into an audio measurement tool that you can use to measure frequencies, musical pitches, amplitudes, and durations.
Paranormal Beeper
This utility app uses complex mathematical algorithms to calculate and detect unprovable moments of reality. It beeps with different audio frequencies when it captures strange or out-of-the-mean values, potentially indicating anomalies.
- Anomaly calculation algorithm
- Probability counting
- Audible alerts with varying frequencies
- Complex mathematical analysis
- Real-time probability checking
- Potential use in paranormal investigations

- Paranormal Beeper calculates unprovable moments of the reality with Mathematics. - It calculates two parts of probability count and if the result is out of the mean, it makes a beep sound. - If it captures any strange value, out of probability, it beeps with different audio frequencies depending on the range. - Complex probability mathematical algorithm calculating failures/anomalies. - It is a simple calculator that takes every 50 milliseconds, the probability of matching between 2 numbers repeated 100 times, combined with the probability of matching 5 numbers out of 5 repeated 25 times, if the result is out of the mean, it is a probabilistic anomaly. - Check it and see if you get any phantom anomaly or if the probability range changes on different locations. - Can be test in paranormal investigations, urbex, abandoned places or locations where there are said to be ghosts or demons.

Verdict
The clearest difference is rating: Spectrolite at 4.8 against Paranormal Beeper's 3.6. Spectrolite also leads on ratings volume (51 vs 5). Paranormal Beeper's advantage is in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Spectrolite sells 1 one-off in-app purchase. Paranormal Beeper asks for nothing beyond the download.
Spectrolite holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: Spectrolite has 51 ratings behind it against 5, so its average is the more settled of the two.
