Analog Stone vs JAX SR
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Analog Stone
This app emulates a classic 1979 four-stage analog phaser pedal, bringing its iconic psychedelic sound to iOS. It offers a focused, hardware-like experience with an optional circuit to reduce harshness for experimental sound design.
- Classic 1979 phaser emulation
- AUv3 plugin support
- Analog modeling engine
- Add-on circuit for reduced harshness
- Manual and external rate modulation
- Supports 44.1, 48, 96 kHz sampling rates

Analog Stone is a focused AUv3 recreation of a legendary 1979 four-stage analog phaser. It brings the character and simplicity of the original pedal to iOS, powered by the same analog modeling engine as RealPhase. Where RealPhase takes the rackmount approach with its 50+ parameters (which can be more than some users need), Analog Stone does one thing beautifully: delivering that iconic, sweeping, psychedelic color with the raw immediacy of physical hardware. The plugin includes an add-on circuit that reduces the harshness and other non-musical artifacts that can emerge at high modulation rates (in free-running mode only). This makes the effect useful even in experimental settings such as glitch effects, with more possibilities to explore when modulating the rate parameter either manually or via external means. PLEASE NOTE: • An AUv3-compatible host is required to use this app • Supported sampling rates: 44.1, 48, 96 kHz • Host tracks must be at least CD-quality (44.1 kHz). Note that some virtual instruments, such as GarageBand’s Smart Instruments, operate downsampled at 22.05 kHz and are unsupported
JAX SR
This audio effect app allows selective frequency range processing for modulation effects. It offers a classic phaser with MIDI control and dynamic mix adjustment, preventing negative side effects from full-range processing. It requires a host application to function.
- Selective frequency range processing
- Classic phaser modulation
- Optional MIDI control
- Dynamic mix adjustment
- Universal app for Apple devices

The manual is here : https://audio.digitster.com/wp-content/uploads/2024/05/JAX-SR-Phaser-Manual.pdf The JAX SR Series are AudioUnits (AUv3), which allow to select a frequency range for effect processing. This one provides a classic phaser modulation effect with optional direct MIDI control assignment to the parameters. If (especially) modulation effects are applied to the entire frequency range, this usually will introduce negative side effects. The JAX [SR] Series allow a selective frequency range and dynamic adjustment of the mix easily. More information can be found on the product website at: https://audio.digitster.com/ Please note, that AudioUnits (AUv3) require a supporting host application to perform. This build (like all our latest releases) is truly 'universal', meaning, the audio unit is available for: - MacOS (Apple Silicon) - iOS (all actual iPhones) - iPadOS (all actual iPads) - visionOS (Apple Vision Pro) Requirements: MacOS 10.15++ iOS 14.0++

Verdict
The clearest difference is update cadence: Analog Stone at every 2 days against JAX SR's every 4 weeks. Analog Stone also leads on price ($5.99 vs $6.99). JAX SR's advantage is iOS requirement (14.0 vs 16.4). On rating, ratings volume, ads and in-app purchases there is nothing between them.
