Strange vs Frequency Detector Tool
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Strange
This app offers unique, evolving distortion effects by feeding audio signals into chaotic mathematical systems. It provides deep control over the distortion's character, from subtle coloring to wild, unpredictable transformations, with post-processing tone shaping and wet/dry mixing.
- Dynamic waveshaping distortion
- Lorenz and Logistic chaos systems
- Adjustable drive and chaos intensity
- Feedback for resonance
- Four distinct distortion modes
- Post-distortion tone shaping
- AUv3 plugin support

STRANGE replaces the static waveshaper with living mathematics. Feed your signal into Lorenz and Logistic chaos systems — attractors that never repeat — and get distortion that breathes, shifts, and evolves. Drive the chaos harder and it warps deeper. Pull back and it colors. The curve is never the same twice. — DRIVE — How deep your signal enters the chaos system. From subtle coloring to full saturation. — CHAOS — Adjusts the density and intensity of the chaotic attractor. Turn it up for wild, unpredictable distortion. — FEEDBACK — Routes the output back into the chaos system. Adds resonance and self-oscillating character. — MODES — Four distortion characters: Fold (wavefolding), Shatter (quantized scatter), Warp (domain warp), Glitch (block displacement). — TONE — Post-distortion tonal shaping. Sculpt the frequency content after the chaos. — MIX — Dry/wet blend. Full wet for pure chaos, blended back for parallel processing. — OUTPUT — Final output level. Compensate for the gain added by drive and feedback. — AUv3 PLUGIN — Run STRANGE inside AUM, ApeMatrix, Audiobus, or any AUv3 host. Multiple instances, each with independent settings. — WORKS ON — iPhone and iPad, all modern screen sizes.

Frequency Detector Tool is a free, elegant frequency and musical-key analyzer for producers, mixing engineers, sound healers, and the musically curious. Type in any frequency in Hertz — like 315, 2.5k, or 29834 — and instantly see: The musical note it maps to (e.g. A4 = 440 Hz) How many cents sharp or flat it is Whether it's IN KEY for the key you've selected The nearest "cut candidate" — the closest out-of-key frequency Vocal context notes to guide your EQ decisions Pick your key from all 12 tones and the whole analysis updates instantly, showing the in-key snap, the nearest cut, and vocal-range context (like the "Mud Zone" around 250–400 Hz). Open the full frequency chart to see every note across octaves 0–7, laid out for boosting and cutting in your chosen key — scroll to explore the entire spectrum. Also included: Clickable Solfeggio frequencies (432, 528, 639, 741, 852, 963) with a note on what each is associated with "Did You Know?" music-theory facts A calm, sacred-geometry inspired interface Frequency Detector Tool is completely free — no ads, no subscriptions, no catch. It's my first app, made with love. If it helps you, an optional donation on eyeheru369.com supports more free tools. Works on iPhone, iPad, and Apple Vision Pro.
