dB Logger vs BedderJet

Free to download. One-time unlock. No subscription, ever. dB Logger turns your phone into a professional-grade sound level meter, frequency analyzer and noise logger — with no account, no cloud, and no subscription, ever. Most sound apps measure your phone's audio AFTER the operating system has "cleaned it up" with echo cancellation, noise suppression and automatic gain. dB Logger doesn't. It captures RAW, UNPROCESSED audio — from the built-in mic or an external USB-C measurement microphone — so what you see reflects the real acoustic field. WHAT PEOPLE USE IT FOR • Measure a noisy neighbor, upstairs bass, or HOA / tenant nuisance — log it over time and export a timestamped CSV + PDF report to attach to a complaint. • Check whether a concert, gig, gym class, bar or restaurant is loud enough to risk your hearing — and how long is safe. • Find out if your baby's white-noise machine is too loud at the crib, and how far to move it. • Assess a room like a consultant: NR and NC single-figure ratings from octave bands for HVAC and building-services work. • Track workplace noise exposure against OSHA, NIOSH or EU limits with the built-in dosimeter. • Check a sound system, studio, AV install or science project with a live spectrum and weighted levels. MEASURE • Real-time dB-A, dB-C, dB-Z with selectable update rate (200 ms to 10 s) • Fast / Slow / Impulse time weighting; current, AVG (Leq), MAX and PEAK • NR (Noise Rating) and NC (Noise Criteria) single-figure room ratings • A noise-source guesser that tells you WHAT is loud, not just how loud VISUALIZE • Live FFT spectrum, 20 Hz – 20 kHz, with peak-hold and peak detection • 1/1 & 1/3-octave equalizer with per-band peak caps • Scrolling time-history graph, color-coded by level • A clean analog dB gauge with AVG / MAX / PEAK LOG, REPORT & SHARE • Log metrics to CSV and raw audio to lossless WAV, independently • Browse saved sessions and generate PDF / CSV reports • Noise Camera: snap a photo or record a video with the live dB reading burned in — clear evidence, easy to share BUILT RIGHT • Guided + manual calibration, saved per microphone profile • USB-C external measurement-mic support, with a visible input picker so you always know which mic you are measuring with • 42 languages; light / dark and Glass / Classic themes • On-device and private — no account, no cloud; your audio and readings never leave your phone unless you choose to share them FREE vs FULL VERSION dB Logger is free to download and fully usable for live measurement — the meter, gauge, spectrum, spectrogram, analyzer and dosimeter are all free and unlimited. The free version also lets you record, export and film video for up to 30 seconds so you can try the whole workflow; those trial clips, exports and reports carry a small "Trial" mark, and the free version keeps two days of dosimeter history. Unlock the full version with a single one-time purchase — no subscription, ever — for unlimited recording, unlimited CSV/WAV/PDF export, full-length video with no watermark, the complete dose history, and no ads. Already bought "Remove Ads"? You're upgraded to the full version automatically, at no charge. Accuracy note: a smartphone microphone is not a certified Class 1/2 (IEC 61672) sound level meter. dB Logger targets reproducible, calibrated relative measurement with standards-correct weighting and rating math. For regulatory or compliance decisions, verify with certified instrumentation.

BedderJet is a native iOS controller for the BedJet V3 climate system. It talks to your BedJet one of two ways: directly over Bluetooth LE when you're in range, or through a Home Assistant instance you already run, using the BedderJet Home Assistant integration. This app does not work standalone out of the box. You need one of the following: • A BedJet V3 within Bluetooth range of your iPhone, or • A self-hosted Home Assistant instance with the BedderJet HA integration installed, plus its URL and a long-lived access token (entered in Settings) Don't have either yet? Open Settings and pick "Try Demo" to explore the full dashboard — climate dial, presets, and the biorhythm editor — with a simulated BedJet. No hardware or account required. WHAT IT DOES • Full climate dashboard — temperature, fan speed, mode, and timers • Dual-bed support with custom bed names • Presets for quick temperature/fan combinations • Biorhythm editor — build a timeline of temperature changes across the night. Save it locally to run from your phone, or, on the Home Assistant backend, upload it as a script that runs entirely on your own HA instance, independent of the app and your phone's connectivity • BLE explorer for inspecting the device's raw characteristics — useful if you're building your own integration TWO BACKENDS, ONE APP • Direct BLE — talks straight to your BedJet's Bluetooth radio. No network involved. BedJet V3 allows only one BLE client at a time, so close the official BedJet app first. • Home Assistant — sends commands to your own HA server over its REST API, using the URL and token you provide in Settings. This is the path to use if you also want to bridge BedJet to HomeKit or Google Home, or if you need more than one client talking to the device. PRIVACY, BY CONSTRUCTION • No analytics, crash reporting, or telemetry SDKs — none, anywhere in the app • No third-party or developer-owned servers. The only network address the app ever contacts is the Home Assistant URL you type in yourself • Your HA access token is stored in the iOS Keychain, not UserDefaults • Bed names, biorhythm sequences, and connection settings are stored locally on-device • Full privacy policy: willsigmon.github.io/bedderjet-privacy BedderJet is built for people who already run Home Assistant, or who want a clean, native, no-account app for direct BLE control of their BedJet — nothing more, nothing less.
