GhostScope
Read full descriptionHide full description
GhostScope is a ghost-hunting kit for fun. It cannot detect ghosts: it shows what your phone's sensors pick up and adds playful tools. EMF METER: shows your phone's real magnetometer reading in ยตT or mG, with a 5-LED bar, peak and live graph. Magnets and speakers move it. Not a scientific instrument. EVP RECORDER: record with the microphone and play back slowed down. Free: 1 recording a day, plus 1 per rewarded ad. SPIRIT RADAR: a radar animation for atmosphere. Blips are random, a visual effect only. SPIRIT BOX: a radio-sweep game. Words are picked at random from a built-in list; a word drops sooner when your EMF reading jumps. Word history included. Entertainment only: nothing is being detected. SENSORS: live pressure, vibration and sound level from the sensors in your phone. PENDULUM: type a yes/no question; the answer comes from how you tilt the phone. HUNT LOG: saves your EMF sessions (duration, peak, events), the last 100. Free with ads. No ads while a hunt is running. GhostScope Pro (subscription or one-time purchase) adds unlimited EVP recordings, m4a export and sensitivity boost above x1.4, and removes ads. No account. Readings and recordings stay on your device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/

Verdict
The clearest difference is in-app purchases: Sound Amp Pro at none against GhostScope's 4. Sound Amp Pro also leads on ads (none vs shown) and update cadence (weekly vs monthly). On price, device support and iOS requirement there is nothing between them.
