HushStep vs SpecWave

Keep your favorite volume and brightness settings one tap away. Every feature is free. No ads, subscriptions, or account required. FINE MEDIA VOLUME CONTROL Adjust iPhone and iPad media volume with a slider, numeric input, and step buttons. Enter precise values and see system readback; the available precision depends on iOS and the current output device. UNLIMITED PRESETS AND SCENE GROUPS Save as many volume presets as you need, optionally including screen brightness. Organize them into groups for reading, working, bedtime, and more. Removing a group keeps its presets. INDEPENDENT WIDGET CONFIGURATION Existing preset widgets remain available. Each new Custom Scenes widget can independently display a group or up to four selected presets. Interactive widgets require iOS 17 or later and open HushStep to apply settings. BRIGHTNESS CONTROL Attach brightness to a preset and optionally reapply it when returning to HushStep. iOS restores system brightness after the screen locks. HushStep does not lock brightness in the background or disable automatic brightness. LOCAL STORAGE Your presets, groups, and preferences stay on your device. No account is needed. Requires iOS 16 or later.
