JAF Model One vs TinyTone
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
JAF Model One
This stereo audio effect plugin offers a virtual analog transistor ladder filter with self-oscillation capabilities. It features audio-rate modulation, onboard saturation for analog drive, and MIDI connectivity for real-time parameter control. Switchable between low-pass and high-pass modes, it can enhance individual tracks or entire mixes.
- Virtual analog transistor ladder filter

The MODEL ONE is a selected, fine-tuned general purpose (transistor ladder model) analog modelled filter with the ability of self oscillation. The cutoff slope is approximately 24dB. It can be switched to low pass or high pass processing mode. The Model One, like all our filter models, is a true stereo processing audio effect, which includes a special audio-rate (high frequency) modulation oscillator, that can modulate the main parameters of the filter to its extremes. The modulation oscillator is not related to the inbuilt unison oscillators, which is a complete separate, different unit. All our models have also an inbuilt additional saturation unit for the extra bit of analog drive. This saturation unit and the oscillator section can be used without the filter module, because the filter unit can be switched to pass the incoming audio signals thru. The available vintage warmer tube/tape saturation type for instance is an excellent choice for breathing life into any obvious digital audio material. It can be applied to entire mixes as to individual tracks and voices. The hosting app for the Model One has special MIDI connectivity, thus parameters can be automated with realtime MIDI Controllers (See MIDI implementation chart). The MIDI features on the audio unit depends on the fact, whether the host application will send MIDI messages to the plugin in any way with the audio processing block or not. The audio unit can be loaded into all supporting audio unit hosts. If successfully loaded into a host, all parameter automation and preset handling will be handled by these host applications.

TinyTone is a full-featured synthesizer sound source for iPhone sound design, stage performance, and recording. Using the on-screen controllers and a MIDI keyboard, you can design and monitor professional synth patches in real time. In addition to standalone app use, ToneEditor can also be loaded as an AUv3 Audio Unit into DAWs such as GarageBand and used as a sound source. It also works as a sound editor for its sister app, TinyTone, allowing you to reproduce consistent sounds with the same sound engine. <Features> ・Powerful Synthesizer Engine Equipped with dual oscillators, envelopes, filters, modulation, delay, limiter, and more. Enables complex sound design. Dual Oscillators with FM Synthesis, switch between Mix and Chain modes for rich tonal possibilities. ・Real-Time Audition Play single notes, chords, and transposition using touch pads. Hear sound changes instantly as you adjust sliders. External input via MIDI keyboard is also supported. ・Preset Management Unlimited user patch storage. ・JSON Export / Import Export patches as JSON. Share via Files app or clipboard. ・AUv3 Support Can be embedded as an AU instrument in DAWs like GarageBand. Reproduces consistent sounds with the same synthesis engine. <How to Use> 【Standalone】 1. Select a preset or start creating from a new patch. 2. Play sounds using the test pad at the bottom of the screen; adjust parameters with sliders to confirm real-time sound changes. 3. Save your created patch to a user slot. 【Using with DAWs (GarageBand, etc.)】 1. Add TinyTone (AU) to a track. 2. Select a factory preset or saved patch from the AU preset selection screen. 3. Play the DAW keyboard to output sound. <Important> ・When using simultaneously with camera or audio apps, noise may occur depending on your environment. Please be careful with output volume. ・Listening to loud audio for extended periods can affect your hearing. When using headphones or speakers, always check your surroundings and volume level. ・Some DAWs (e.g. Ableton Live 11) may not detect iOS-app AUv3 plug-ins. Logic Pro, MainStage, and GarageBand are recommended. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://flicker-jp.com/privacy

Verdict
The clearest difference is price: TinyTone at Free against JAF Model One's $9.99. TinyTone also leads on rating (5.0 vs 4.7). JAF Model One's advantage is ratings volume (15 vs 1) and device support (3 vs 1). On update cadence, ads and in-app purchases there is nothing between them.
