Codable is a lightweight web developer toolkit for iPhone and iPad. Use the Safari extension to inspect pages where they already run. Select elements inline, browse the DOM tree, view HTML, inspect styles and node metadata, evaluate JavaScript, capture console output, view source, inspect resources, and review network activity. On supported devices, on-device Apple Intelligence can be used to find elements and perform edits. The main app has three tabs for development and testing: - Resize: a browser surface for testing responsive layouts with custom viewport width, height, scale, presets, and drag handles. - Scratchpad: a JavaScript editor and runner with syntax coloring, code-focused keyboard shortcuts, document support, and optional Apple Intelligence assistance on supported devices. - Extension: a small info page with instructions on how to enable the Safari extension, and a way to view a local demo page with CSS, JavaScript, resources, console logs, and network requests to try out the tools within Safari.

App Volume — the per-app volume control iPhone & iPad have been missing. Going from a quiet podcast to TikTok? No more eardrum panic. Each app gets its own volume — and now a second one just for Bluetooth headphones. Stop mashing the side button every time you switch apps. App Volume uses Apple's official Shortcuts engine — no jailbreak, no warranty risk, no advertising tracking. — WHY IT EXISTS — iOS has ONE global media volume: whatever you played last sets the level for whatever you open next. Spotify-to-TikTok startles everyone on the bus, and your ears want different levels on headphones than on the speaker. Apple never built per-app volume — so we did, the official way, on Apple's own Shortcuts engine. — HOW IT WORKS — 1. Create a mode and add your apps with their target volumes (TikTok 30%, Podcast 70%, Netflix 80%). 2. The in-app guide walks you through installing our pre-built template in Apple Shortcuts once. Whenever you add another app later, add it to the list of apps that trigger your existing Personal Automation. 3. Follow the in-app animation to set up one Personal Automation — switching apps auto-applies the right volume. 4. Add the widget to Lock Screen, Home Screen, or Control Center — tap to switch the whole mode in one go. — NEW: HEADPHONE VOLUMES — Turn on "Separate headphone volume" for any app to give it a second, headphone-only level. Bluetooth helper automations handle the switch when they run; wired headphones aren't supported. — USE CASES — • A volume per app — Podcast 70%, music 60%, video 80%. Set once; switching apps auto-applies. • Ears vs room — TikTok at 25% on AirPods, 60% on the speaker. — FEATURES — • Per-app volume targets — an independent volume for any app • Headphone volumes — a second per-app volume that applies while Bluetooth headphones are connected • Modes — bundle rules into named modes, swap the whole set instantly • Global rules — pin an app's volume across every mode; great for games that should always open muted • Ready-made modes — browse Discover, install Bedtime or Silent Game Ads in one tap • Share your setup — send any mode as a picture + link a friend can import • Widgets everywhere — Lock Screen, Home Screen, Control Center (iOS 18+): see the active mode, tap to switch • Switch notifications — silent banner by default, sound + haptic, or off • iCloud backup — modes backed up to your iCloud — GOOD TO KNOW — Honest limits, no surprises: • One volume at a time: App Volume sets the system volume the moment you open or switch to an app. iOS can't mix two apps playing at once — a video during a Discord call shares one level, and no App Store app can change that. • It shines with apps you actively open and switch between. Audio already playing in the background keeps its level until you return to that app. • Headphones: Bluetooth helpers apply the headphone level when they run; speaker volume may take a few seconds to return after disconnecting. Wired headphones aren't supported because Shortcuts only provides automation triggers for Bluetooth connections and disconnections. — PRIVACY FIRST — • No ad tracking or data sales. We collect basic analytics and crash reports. Feedback you choose to send reaches us with its text, optional email, app/build and iOS versions, device model, and locale. • No microphone, no location, no contacts • Troubleshooting guide • Privacy Policy in Settings → Privacy — SUPPORT — Use the in-app feedback button to reach us directly — we read every message.

Verdict
The clearest difference is review sentiment: App Volume at 67% against Codable's 0%. App Volume also leads on update cadence (weekly vs monthly) and iOS requirement (18.2 vs 26.4). Codable's advantage is rating (4.3 vs 3.5) and in-app purchases (none vs 1). On price, ratings volume, ads and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. App Volume sells 1 one-off in-app purchase. Codable asks for nothing beyond the download.
Codable holds the better App Store score, 4.3 against 3.5. Both are backed by a comparable volume of ratings — 6 and 6 respectively. Written reviews complicate that: 0% of Codable's written reviews are positive against 67% of App Volume's, so the app with the better star average is not the one people write more warmly about.
Codable ships an update monthly, App Volume weekly. Both last shipped on October 12, 2026.
