Scroll Volume Remote vs Sound Meter

Scroll Volume Remote is the free iPhone companion to Scroll Volume for Mac — a macOS utility that turns the menu bar into a volume target. This app on its own does nothing useful. Its only job is to remotely control the Scroll Volume Mac app from your phone, by acting as a wireless volume wheel. If you do not own and run the Mac app, there is nothing here for you. WHAT IT IS, AND WHAT IT IS NOT This is not a generic "Mac remote" or a universal volume controller. It cannot adjust the volume of a Mac that does not have Scroll Volume installed and running. It cannot control any other application, system setting, or media playback. It cannot connect to anything other than a Mac running Scroll Volume. It is a single-purpose add-on to one specific Mac app. If you have the Mac app: this is a small, free bonus that lets you change your Mac's volume from a few meters away. If you do not have the Mac app: please install it first from the Mac App Store. The Mac app is the product. This app is the remote. HOW IT WORKS WITH SCROLL VOLUME FOR MAC Install Scroll Volume for Mac from the Mac App Store on your Mac. Launch it. Then open this app on your iPhone — it will look for Macs nearby that are running Scroll Volume, and offer to pair with them. Tap to pair. From then on the two devices recognize each other automatically. Spin the wheel on the phone, and the Mac's system volume changes — one notch on the phone, one step on the Mac. Mute and unmute work too. The two devices communicate directly using Apple's MultipeerConnectivity framework over Bluetooth and the local Wi-Fi network. There is no router-only requirement, no internet involved, and no servers in the middle. We do not run any. Traffic stays on your local link. KEY POINTS • Free companion to the Scroll Volume for Mac app — does nothing without it. • Acts as a wireless volume wheel for the paired Mac running Scroll Volume — fluid, one notch per step. • Direct device-to-device link over Bluetooth and local Wi-Fi. No internet. No accounts. No servers. • Pair once, reconnect automatically. The app remembers Macs you have paired with. • Single-purpose. The app does this one thing and nothing else. PRIVACY BY DEFAULT Scroll Volume Remote collects nothing. No accounts, no analytics SDKs, no advertising identifiers, no crash reporting services, no third-party trackers. The only thing the app keeps on disk is the name of Macs you have paired with so it can reconnect. That information never leaves your device. The app runs in the iOS sandbox. PERMISSIONS • Local Network — required so the app can discover your Mac on the same Wi-Fi network. You will be prompted on first launch. • Bluetooth — required so the app can discover and talk to your Mac when there is no shared Wi-Fi network, using Apple's peer-to-peer Bluetooth. REQUIREMENTS iOS 16 or later. A Mac with Scroll Volume for Mac installed and running. The Mac app is sold separately on the Mac App Store and is required — this iPhone app has no use without it. The two devices need to be on the same local Wi-Fi network, or have Bluetooth turned on, to discover each other.

A sound level meter for iPhone that is honest about what it does not know. Point your iPhone at a sound and it tells you how loud it is, in decibels, using the weightings and time constants a real sound level meter uses. Record a session and you get the statistics that matter afterwards — the energy average, the peak, the quietest moment — plus a CSV or PDF you can send to someone. EVERY PRO METRIC IS FREE Not a trial, not a teaser. The full measurement feature set is in the free version, and paying only removes the advertising. • LAeq — energy-average level • LCpeak — instantaneous peak • LAFmax and LASmin • A, C and Z frequency weighting • Fast and Slow time weighting • FFT spectrum with dominant frequency • Octave and 1/3-octave band analysis • Session recording, history and notes • CSV and PDF export MEASURE THE WAY YOU NEED TO Keep measuring with the screen locked. Watch the live trend. See what the noise compares to in plain words. Set a warning level and feel it rather than watch for it. THE HONEST PART This is not a certified sound level meter and it does not pretend to be. Readings are labelled Approximate in the app and in every export, because the absolute level rests on a provisional constant rather than a calibration measured against a reference instrument. Use certified equipment wherever a regulation requires it. When there is no measurable signal the reading is "--", not "0" — a covered microphone is not a quiet room. When measurement pauses, the number disappears rather than freezing at its last value. Connect a Bluetooth or USB-C microphone and the app says so, and refuses to apply a correction that was never measured for it. YOUR SOUND STAYS ON YOUR PHONE Audio and measurements are processed on your device without an account or upload to our servers. Microphone access is needed for measurement. The free version uses Google AdMob, which processes device and advertising information but does not receive your audio, measurements or recorded sessions. Advertising privacy choices and Apple tracking permission are handled separately. Requires iOS 17 or later. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
