Room Tuner: Speaker & Room EQ

Your room is half your sound system. Measure it with your iPhone, get an honest score, and fix the biggest problem first — free moves before you spend a cent.

Every hi-fi, home theater, and soundbar sounds only as good as the room it's in. Room Tuner turns your iPhone into an honest room-and-speaker measurement tool — then coaches you through fixing what it finds.

MEASURE HONESTLY — FREE • Play a short test sweep through an AirPlay 2 speaker, receiver, or Apple TV • Take a Quick reading or walk a balanced 5, 7, or 9 positions around your usual listening spot for a Trusted result • See a 0–100 score for a typical measured position and the combined average response from the room • Understand bass, mids, and highs in plain language, with the top-ranked next move free in your room • Keep honest limits visible: unsupported or inconclusive evidence is labelled, never filled in with a guess • Use built-in iPhone microphone correction, or import a calibration file for the iPhone microphone model (.cal/.frd). External measurement microphones are not supported.

IMPROVE ONE THING AT A TIME Room Tuner ranks practical experiments by audible impact. It starts with free placement and listening-position moves, then setup changes, treatment, and EQ only when the measurement earns it. Re-measure after a change and keep the before reading protected.

GO PRO: THE FULL COACHING PROGRAM • The complete ranked improvement plan • Guided tuning, speaker-placement, subwoofer-placement, and phase experiments with a measured keep/change-back verdict • An optional per-speaker pass for eligible stereo setups. Left/right findings appear only when Room Tuner verifies acoustic separation; otherwise the main room result remains valid and no per-speaker conclusion is used. • Exact parametric EQ only from a Trusted reading when the measured evidence is safe enough, with export for REW, miniDSP, Wavelet, and .frd • Unlimited rooms and before/after comparison

Room history, change logging, and room export remain available free.

PRIVATE BY DESIGN No accounts, analytics, advertising, or tracking. Audio is processed on your device and never saved. Measurements and setup answers stay on your iPhone.
