Smart Noise Detector vs LockBoard

Smart Noise Detector helps you capture sounds that stand out from the background. Start monitoring, let the app measure the room for three seconds, and it will record automatically when the sound crosses your chosen threshold. AUTOMATIC RECORDING • Monitor relative sound levels in real time. • Choose a threshold of +12, +18, or +24 dB above the ambient baseline. • Save each sound event as a separate M4A file. • Stop each recording after two seconds below the threshold. • Recalibrate when your surroundings change. • Continue monitoring with background audio support. FIND AND SHARE YOUR RECORDINGS Review recordings by date, time, and duration. Play a recording or tap Share to send the audio file through the iOS share sheet, use AirDrop, or save a copy to Files. Tap Select to choose several recordings or select all, then review the count before deleting. Canceling keeps your selection, and any recordings that cannot be deleted stay in the list so you can try again. ENGLISH AND KOREAN The app supports English and Korean, with English as the default for other device languages. YOUR RECORDINGS STAY WITH YOU Recordings are stored on your device and remain available when you update the app. NoiseDetector does not collect your recordings or upload them to a server. Audio leaves the app only when you choose to share it. Sound levels are relative to your device microphone and are not calibrated sound pressure measurements. Use the app to review everyday sounds, noise events, or barking while monitoring is active.

LockBoard keeps your notes on your Lock Screen wallpaper — always visible, zero effort. The fundamental weakness of to-do apps: they only work if you open them. LockBoard turns your note itself into your wallpaper, so it catches your eye every time you pick up your phone. Like a sticky note on the fridge, it works without you even trying — on the screen you look at more than any other. ■ Just write and close - Open → write → close. That's all - The wallpaper image refreshes automatically the moment you close the app - One board only. No lists to manage, nothing to organize ■ What you see is what you get - The preview shows exactly what your Lock Screen will look like - Backgrounds: 6 calm solid colors, 6 gradients, or a photo you love - Adjust text size, vertical position, and a readability backdrop - The layout stays clear of the Lock Screen clock and bottom buttons ■ How it works (one-time setup, about 2 minutes) iOS doesn't let apps change your wallpaper directly. LockBoard pairs with Apple's official Shortcuts app to update it. All you set up the first time: add the ready-made shortcut with one tap, assign it to a button on your Lock Screen, and write your first note from that button. The in-app wizard walks you through it screen by screen — about 2 minutes. After that, you can jot things down straight from the Lock Screen button. To have edits you make inside the app applied automatically too, you can go on to set up the optional "when the app closes" automation. ■ Great for - Keeping this week's goals in sight without relying on willpower - Anyone who could never stick with a to-do app - Shopping and packing lists you can check at a glance - Words you live by, always in view - Drilling facts for exams and certifications ■ 7-day free period and pricing - Try every feature free for 7 days (168 hours) after your first successful shortcut action - The free period does not start a subscription or charge you automatically - After it ends, you can still view and copy your memo, share the wallpaper, and keep your current Lock Screen wallpaper in place.
