NEW: SYSTEM INTELLIGENCE Build your system in the app and tap Analyze. Audiophilio reads your signal chain and flags what's off — a missing phono stage, speakers with no amp, a source bypassing your DAC, a tonearm/cartridge resonance mismatch, amp/speaker impedance and headroom, and more — each ranked by severity with a specific fix, plus what your setup gets right. Link a room for size- and treatment-aware advice, plus a private on-device AI summary on Apple Intelligence devices. MEASURE • SPL Meter — real-time sound pressure levels with A/B/C/Z weighting and peak hold • Real-Time Analyzer — 1/3-octave spectrum analysis, live • LUFS Meter — momentary, short-term, and integrated K-weighted loudness • Waterfall Plot — scrolling spectrogram with an interactive 3D view for room modes and decay • Spectrogram — 2D frequency map for resonances and flutter echo • Oscilloscope — live triggered waveform display • Frequency Response & PEQ — log-sweep measurement with up to 32 parametric EQ suggestions; REW, MiniDSP, and Equalizer APO export • RT60 Measurement — reverberation time per octave band • Energy Time Curve — direct sound, reflections, and ITDG • Channel Balance — L/R level and timing offset • Impedance Analyzer — resonance sweep for Fs and port tuning • THD+N Analyzer — distortion via sweep, with a per-harmonic profile (H2–H8) • Wow & Flutter Meter — speed stability from a 3150 Hz test record, with peak/RMS deviation and a grade • Delay Finder — speaker-to-listener delay and distance • Polarity Checker — correct or reversed speaker wiring • Noise Generator — white, pink, and brown noise for burn-in and acoustics Every measurement tool shows your active input — UMIK-1 or built-in mic. DIAGNOSE System Diagnosis analyzes your RT60, channel balance, distortion, polarity, impedance, and early-reflection data, then ranks every issue by severity with plain-English fixes — with deeper on-device AI analysis on Apple Intelligence devices. DESIGN & SET UP • Room Designer — interactive 2D/3D visualization with standing-wave heat maps, first-reflection analysis, toe-in arcs, and room-mode labels; LiDAR scan on supported devices. • System Builder — document your full signal chain with flow diagrams and run System Intelligence on it; export the component list as Markdown with one tap. • Turntable Setup Suite — tonearm alignment (Baerwald, Löfgren A, Stevenson) with a null-point diagram, tracking-force and anti-skate reference, and a setup checklist. • Ear Trainer — learn to identify frequencies by ear across all 31 ISO 1/3-octave bands, each with a description of what you hear and a "listen for" tip, plus a scored quiz. CALCULATE Eleven acoustic calculators: Room Modes, RT60 (Sabine), SBIR, First Reflection Point, Schroeder Frequency, Crossover, dB Converter, Ohm's Law, Speaker Distance, Cartridge Resonance, and Thiele-Small Parameters. COMMUNITY Share your rooms and systems, browse how others listen, follow fellow listeners, and join the Audiophilio Facebook group. Shared Test Tracks: share the reference tracks you use to evaluate gear — with a "what to listen for" note, test-attribute tags (soundstage, sub-bass, imaging, vocals, dynamics, and more), and links to the services you use. Play in the app: a 30-second preview for everyone, or full tracks for Apple Music subscribers. PRICING Free: SPL Meter, Noise Generator, Ear Trainer tones, all calculators, one room, one system, iCloud sync, and community. Premium ($44.99, one-time): everything else — all measurement tools, the vinyl suite, System Diagnosis, System Intelligence, unlimited rooms and systems, advanced overlays, LiDAR scan, and export. No ads. No subscriptions. No tracking. Just the tools. ## Audiophilio Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0e/3b/ab/0e3bab89-3e1c-26f1-a99d-d5e5d41238b1/iPhone-01-SPL.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/41/8d/75/418d7566-3650-bac8-cbe3-04da63e5b606/iPhone-02-Listening-Room.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/a3/85/b5/a385b5be-6bdd-151f-9812-b5a9cfcef723/iPhone-03-waterfall.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/77/28/ae/7728ae28-23bc-fa0b-e418-86bd58343623/iPhone-04-RTA.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/e5/f8/23/e5f823a3-af25-76ee-8a28-e862d21984e0/iPhone-05-System-Diagram.png/1320x2868.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/46/80/f6/4680f686-7565-a9d9-0e5b-a106037b6b2e/iPhone-06-FR.png/1320x2868.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/4e/bc/e6/4ebce6cc-8608-f183-72bc-14df89335288/iPhone-07-RT60.png/1320x2868.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/33/6c/60/336c6022-b30c-04a1-9d3e-2d4878e19ace/iPhone-08-LUFS.png/1320x2868.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/36/3c/48/363c4832-847e-2be3-de62-ea1e1a537b80/iPhone-09-Spectrogram.png/1320x2868.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/04/0e/55/040e55ad-c64a-07cb-9b30-f760b1077c43/iPhone-10-Tools-List.png/1320x2868.png) ## Audiophilio In-App Purchases | Item | Price | |------|-------| | Audiophilio Premium | 368.00 H$ | ## Audiophilio Available In - [Germany](https://apptail.io/app/audiophilio-iKBz/germany) - [Ecuador](https://apptail.io/app/audiophilio-iKBz/ecuador) - [France](https://apptail.io/app/audiophilio-iKBz/france) - [Hong Kong SAR China](https://apptail.io/app/audiophilio-iKBz/hong-kong) - [Japan](https://apptail.io/app/audiophilio-iKBz/japan) - [South Korea](https://apptail.io/app/audiophilio-iKBz/south-korea) - [Poland](https://apptail.io/app/audiophilio-iKBz/poland) - [Portugal](https://apptail.io/app/audiophilio-iKBz/portugal) - [Romania](https://apptail.io/app/audiophilio-iKBz/romania) - [Sweden](https://apptail.io/app/audiophilio-iKBz/sweden) - [Singapore](https://apptail.io/app/audiophilio-iKBz/singapore) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
