Ollin already knows the answer - because you told it. The Ollin Tuner looks like a mystical Aztec oracle, and sounds like one too: ask a question, hold the dial, and a deep ancient voice delivers the reading. But here's what nobody watching will know - you decide what it says. HOW A TRANSMISSION GOES DOWN - Your friend asks a question out loud - You type it in - and secretly plant the answer - The dial awakens, the frequency locks in - Ollin speaks their exact answer back in a voice from another age Their jaw drops. And when they grab your phone to try it themselves? The oracle gives them a genuine mystic reading - and gives nothing away. FEATURES - A living Aztec Sun Stone dial that moves and pulses under your fingers - Cymatics sand particles that shift and respond as the dial awakens - Readings spoken aloud in a deep ancient voice - Genuine AI-powered mystic transmissions for everyone who isn't in on it - Dramatic full-screen reveals that feel like intercepting a lost signal - A guided initiation that teaches you the secret and how to perform it
GhostScope

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 µT 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 ads: The Ollin Tuner at none against GhostScope's shown. GhostScope's advantage is update cadence (every 5 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
