VolBud is the AirPods volume manager that Apple should have built. If you have ever been blasted by a sudden volume spike, struggled with the lowest step still being too loud, or wished your AirPods would just remember your preferred volume, VolBud is for you. PRECISE VOLUME CONTROL Go beyond Apple's 16-step volume. VolBud gives you 1% increment control so you can find the exact level that feels right, whether you are falling asleep or working in a quiet office. VOLUME SPIKE PROTECTION Sudden volume jumps can damage your hearing. VolBud monitors your audio in real time and automatically corrects dangerous spikes before they reach your ears. View a full history log of every spike event. SCENE-BASED PRESETS One tap to switch between Sleep, Commute, Work, and Sport modes. Each preset remembers your ideal volume level. VolBud automatically restores your preferred volume when your AirPods reconnect. VOLUME LIMIT LOCK Set a maximum volume limit and never worry about accidentally turning it up too high. Perfect for parents who want to protect their kids' hearing. SLEEP MODE Drift off with a timer that gradually lowers your volume over time. Wake up to silence instead of a podcast still playing at full blast. ONE-STOP AIRPODS SETTINGS No more hunting through four different iOS Settings pages. VolBud brings all your AirPods configuration into one clean, intuitive interface. CONTROL CENTER WIDGET Adjust your volume right from Control Center without even opening the app. Quick access to your favorite presets. DYNAMIC ISLAND SUPPORT See your current volume level and protection status right on the Dynamic Island. Always know your audio status at a glance. SHORTCUTS INTEGRATION Create Siri Shortcuts and automations for volume control. Set up triggers like "when I arrive at work, set volume to 40%."
