Free tiles
Classic EVP
Clean microphone capture for classic review. No noise bed and no magnetic carrier.
Spirit Box
Radio-scan carrier plus mic. Classic Scan is the free start.
Pro tiles
Spirit Speak
Ask and listen for a reply. Dictionary lines as YOU / SPIRIT. Same feature as Live Chat on EMF and SLS.
Spirit Music Box
Calibrated multi-sensor chime. Several channels must move together before it sounds.
SLS
Stick-figure AR tracking of human-shaped forms, plus session video of that view.
On EVP
EVP options after you tap the tile
EVP starts on clean capture. Optional extras on that screen are Knock, Estes, and Vigil. Review options on EVP include a noise bed, a magnetic carrier, magnetic plus phonemes, and lo-fi VAS. Those are EVP options, not their own home tiles.
On Spirit Box
Classic Scan
AM-style station hops with radio static. The free Spirit Box start.
Live Radio
Static-first with short word escapes. Needs Wi-Fi or data. Falls back to Classic Scan when offline.
Extra banks & live FX
Synthesized banks such as Reverse Scan, plus live echo and reverb on the carrier, stay Pro.
Tools
What stays free - and what wears a PRO badge.
