*** This is an AUv3 extension and not a standalone app. *** *** It requires a host app like Garageband or similar. *** VividShaper is a cutting-edge AUv3 plugin synthesizer akin to a wave table synth that gives you the power to design your own waves in real-time. Its unique interface allows you to program your own waves with the built-in Lua programming language, offering a level of customization and control unparalleled in the world of digital music production. With VividShaper, you can dynamically change your waveforms over time, bringing a whole new level of creative possibilities to your music. Use up to 16 generators for polyphony, and 8 oscillators per generator, to create rich, intricate sounds. Each oscillator wave can be manipulated in Lua code in real time, giving you full control over your sound design. The plugin supports iCloud, so you can share your patches between both iOS and macOS devices.
StringLab
This app is a digital synthesizer that uses physical string modeling to recreate the sounds of various instruments, particularly plucked or hammered strings. It allows users to explore acoustic physics and create unique instrument textures through extensive parameter experimentation.
- Karplus-Strong physical modeling
- Exciter Impact and Noise modes
- Resonator objects with feedback
- Frequency Dispersion support
- External live input
- Preset randomizer and manager
- Drag & Drop preset export

StringLab is a physical string modeling synthesizer based on Karplus-Strong theory. It is capable of reproducing the sounds of many different types of instruments, but is especially useful in the reproduction of hammered or plucked strings and other types of percussive instruments. It works by passing carefully crafted waveforms and short bursts of white noise through a series of tuned delay lines. The delay lines have an internal feedback loop with a series of filters to mimic the natural decay of harmonics found in a real instrument. StringLab allows you to discover the character of real-world accoustics, exploring the physics of how materials interact. Many new and original textures are born out of experimenting with the settings, so don't be afraid to experiment and create your own unique and dynamic instruments. Features •Karplus Strong based physical modeling. •Exciter Impact with multiple modes. •Exciter Noise with many envelope driven filters. •2 resonator objects with feedback. •8 bands per object with inversion. •4 Coupling modes. •Supports Frequency Dispersion. •Feedback low/high Damping. •Per object Body Filter. •Pitch Deformity. •External live input mode. •Preset randomiser. •Build it Preset Manager & Favourites. •Search Presets. •Drag & Drop preset export of presets. •Supports Color Sets.

Verdict
The clearest difference is rating: VividShaper at 5.0 against StringLab's 4.3. VividShaper also leads on price ($5.99 vs $14.99) and review sentiment (83% vs 57%). StringLab's advantage is update cadence (every 10 days vs every 4 months) and iOS requirement (13.0 vs 16.0). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
