Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SUBscription Synth
This app transforms user-entered text into unique monophonic sub-synth waveshapes. It offers a text-to-synthesis engine, drive and dirt effects, a low-pass filter, and extensive modulation options for creating powerful bass sounds.
- Text-to-synthesis engine
- Monophonic sub-synth
- Drive and dirt effects
- 12dB/oct low-pass filter
- 2 envelopes, 2 LFOs, 4 expression controls
- AUv3 plugin and standalone operation

To celebrate international joke day 2023, we decided to take a big step with our first synthesizer plugin; SUBscription. While based on a tongue-in-cheek pun about the current state and direction of the music tech industry, we actually ended up with a surprisingly excellent plugin that takes user-generated phrases (subscription codes) and converts them into unique waveshapes in a monophonic sub-synth. - Create powerful, characterful bass sounds - Unique and exceptionally high IQ text synthesis technique ^TM - Reasonable subscription models - Unequivocally superior, requires no review. SUBscription Upon entering a subscription code into our brand new text-to-synthesis engine, you are entering a world of sonic enrichment and fame, but you may have to make a deal with the devil. Text Synthesis Create characterful wave shapes using our experimental new text-to-synthesis technique. We have prepared every possible character combination (subscription code) because you’re weak and predictable. Drive & Dirt Boost the ever loving **** out of the synth with some crispy drive. Use the Dirt knob’s Rate modulation to thicken and filth up your tracks with noisy textures. Filter Carve your frequencies out with the 12dB/oct low-pass ladder filter. Much like the filter, we too will be filtering out any bug reports, requests or errors - our time is far more important. Modulation Add movement to your sounds with 2 envelopes, 2 LFO’s & 4 expression controls which are assignable to nearly every parameter. Unlike the fluid nature of modulation, we stand firm with our decisions - you just wouldn’t get it. Product Aftercare If you need support via email you’ll have to deal with harshly worded, incredibly frustrated developers and please note that all critical feedback of any nature will be met with serious scolding. SUBscription is designed as an AUv3 plugin, meaning it works within iOS and iPadOS hosts such as Logic Pro, GarageBand, Cubasis 3, AUM and Beatmaker 3. SUBscription also works as a standalone instrument.
FAC Fizzica
This app infuses audio with dynamic digital textures and movement through audio-rate modulation. It features an integrated envelope follower for expressive sound shaping and supports various modulation sources for unique sonic transformations. Optimize your workflow with an intuitive XY control pad and visual spectrum display.

• Infuse your sound with digital artifact textures • Integrated envelope follower for dynamic sound expression • Supports noises, oscillators, and internal/external audio modulation models • Side mix control to balance between fully processed signal and sidebands • Sidechain support: external envelope follower and audio model • Optimized workflow with an easy-to-use XY control pad • Spectrum display of the output signal • MIDI control: Envelope via CC, main frequency and filter cutoff via notes • Extended version of FAC Punchlab's Fizz module • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro Infuse your sound with dynamic digital textures and movement using audio-rate modulation. FAC Fizzica extends FAC Punchlab's Fizz module, maintaining its intuitive design while introducing advanced features for extensive sound shaping. FAC Fizzica is your go-to solution for achieving a vintage lo-fi aesthetic and enhancing audio by adding digital noise artifacts that dynamically respond to your audio input. Ideal for refining basslines, pads, drum loops, and any elements requiring organic and expressive transformations. The plugin offers dynamic expression thanks to its envelope follower, an essential processor in sound design that effectively transforms static sounds into dynamic motion. The envelope follower can monitor the audio input, the sidechain input, a dedicated automatable parameter, or a MIDI CC message. You can adjust the modulation depth for each controlled parameter, precisely controlling how the envelope affects them. To provide a wide variety of textures and timbres, the plugin offers several models. The noise models introduce noisy artifacts, while the sine and triangle models enhance harmonic and tonal richness reminiscent of FM synthesis or RM modulation. The final models allow the use of either the internal or external audio signal (sidechain) as a modulator to affect your carrier signal, offering an interesting method to subtly blend the characteristics of one sound with another. Another standout feature of FAC Fizzica is the sideband control, which adjusts the balance between the processed signal and the isolated sidebands generated by the audio rate modulation. At maximum, only the sidebands are audible! Additionally, a built-in low-pass filter refines the tonal color of the digital textures. The workflow is optimized for simplicity and intuitiveness, featuring a central XY control pad for precise control, accompanied by a detailed visual representation of the envelope signal and all the modulations. Additionally, a spectrum viewer displays the audio output, providing clear visual feedback as you craft your audio to perfection. The plugin comes with two extensions, both audio effects, but the second one also supports MIDI input to control the main frequency and the filter cutoff with MIDI notes, as well as the envelope follower with MIDI CC messages. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Fizzica.html

Verdict
The clearest difference is in-app purchases: SUBscription Synth at none against FAC Fizzica's 3. SUBscription Synth also leads on price ($2.99 vs $9.99) and update cadence (every 2 days vs every 7 months). FAC Fizzica's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 88%). On ads, monetization model and device support there is nothing between them.
