EffectDeck puts an effect chain on the audio other apps are already playing, and the effects you can put in it are not limited to the ones it ships with. Pick EffectDeck as the output in Control Center, then open the app and build a chain. No virtual cable, no routing to set up, nothing to configure first. Start from over 100 of EffeTune's effects, running unmodified: the same DSP code EffeTune runs on the desktop and on the web. Add the AUv3 plug-ins already on your device and your own impulse responses. When the effect you want does not exist, write it as a JSFX script, and it goes into the chain like any other effect. WHAT YOU GET - Over 100 built-in effects: EQ, dynamics, saturation, modulation, reverb, delay, spatial, lo-fi and restoration - JSFX effects: import a script from Files, a link or the clipboard. Each gets its own sliders and, if it draws, its own display - AUv3 effec…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be.

What the numbers say: EffectDeck runs a light set with one background colour (#FCFCFC) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #048CFC, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
