Ear Spy vs OPCam

Spy Ear turns your phone into a long-range listening device. With your microphone and headphones, you can amplify ambient sound in real time and pull faraway voices closer - a quiet conversation across the room, a distant speaker in a hall, the hum from the next room. WHAT YOU GET • 8 environment presets — Restaurant, Lecture, Whisper, Meeting, Outdoor, TV, Music, Balanced • Full 10-band parametric equalizer — shape every frequency yourself • Personal hearing calibration — a two-minute tuning that adapts every preset to your own ears • Unlimited clip capture — save what you heard, replay it through the same enhancement chain • On-device live transcription — see what is being said • Hearing-safety limiter — prevents sudden loud sounds from damaging your ears • Zero data leaves your phone — everything is processed on-device BUILT FOR REAL SITUATIONS Whether you want to follow a quiet conversation at dinner, catch every word in a lecture, hear the TV more clearly, or simply explore what's beyond your normal hearing range, Spy Ear gives you the sharper listening superpower in your pocket. Use of headphones is strongly recommended. SUBSCRIPTION REQUIRED Spy Ear requires a paid subscription or a one-time lifetime purchase to use the full app after onboarding.

OPCam turns your iPhone into a tamper-evidence camera for fieldwork, inspections, and any photo that has to be trusted. • Time, GPS coordinates and address are burned into the original photo — they can't be edited out • Every photo gets a SHA-256 fingerprint of the exact image file you share — so anyone holding the photo can recompute it and check it themselves • Optional on-chain anchor: the fingerprint is recorded on Optimism, so anyone can independently verify the photo existed at that time • Record library with timeline, place and live map views • Choose exactly which fields go into the watermark • 24 languages Your photos stay yours — saved to your photo library. The on-chain anchor stores only a hash fingerprint, never the image.
