Built with true analog-style bucket brigade circuitry, this plugin is a modern reissue of some of the most iconic hardware units, faithfully capturing their distinctive tone. The effect ranges from subtle doubling to rich, swirling modulation, covering different uses as a Chorus, Flanger, or Vibrato. The expanded modulation controls, multiple characters, and LFO waveforms allow precise shaping of your sound, giving you complete creative flexibility. In addition, the feedback control adds rich, flanger-like textures for dynamic sonic effects. Under the hood, the plugin uses two individual delay line paths. Each path’s behavior is determined by the character parameter: Thick and BBD provide warm, classic BBD-style tones, while Clean delivers a more transparent tone with greater modulation.

Verdict
The clearest difference is in-app purchases: VividShaper at none against FAC Chorus's 3. VividShaper also leads on rating (5.0 vs 4.8) and price ($5.99 vs $6.99). FAC Chorus's advantage is review sentiment (95% vs 83%) and ratings volume (61 vs 8). On update cadence, ads, device support and iOS requirement there is nothing between them.

VividShaper holds the better App Store score, 5.0 against 4.8.

Written reviews complicate that: 95% of FAC Chorus's written reviews are positive against 83% of VividShaper's, so the app with the better star average is not the one people write more warmly about.
FAC Chorus ships an update every 5 months, VividShaper every 4 months. The most recent releases landed on September 22, 2026 and September 19, 2026 respectively.
