Decibels vs Network Radar Ultra

Decibels is a sound level meter that remembers what you measured. Point it at the noise, press start, press stop — and the reading stays. Average (Leq), maximum, minimum, duration and the full level trace, saved automatically, every time. No account, no subscription, and nothing leaves your phone unless you send it. MEASURE • A-weighted (dBA) or unweighted, per IEC 61672 • Fast (125 ms) and Slow (1 s) time weighting • LCpeak for impulses — alarms, slams, machinery • Live level trace with a ten-second window • Calibration offset for matching a reference meter KEEP • Every measurement saved automatically • History with the full trace of each run • CSV export carrying the settings it was taken under Decibels stores your measurements on your device and nowhere else. It records no audio — only the level — and asks for no location, no account and no identifiers. A note on accuracy: a phone microphone is not a calibrated instrument. Decibels is honest about that. Use the calibration offset against a reference meter for absolute readings, and treat it as an excellent relative instrument otherwise.

Network Radar Ultra finds devices on your local network and clearly shows what is actually reachable: IP addresses, device types, open ports, web interfaces, and local services. Start a scan on the connected WiFi network and identify routers, repeaters, cameras, printers, NAS, Sonos, Apple TV, smart home devices, KNX/IP, Home Assistant, and unknown devices. Bonjour/mDNS, UPnP/SSDP, ONVIF, HTTP hints, and TCP port checks are combined so names, models, and device types appear as cleanly as possible. The analysis gives you a clear network summary: • found devices and device types • open ports and web interfaces • Bonjour and UPnP/SSDP services • ONVIF/RTSP hints for cameras • notable or unknown devices • scan history with comparison The tools section includes practical network diagnostics: • reachability check • port check and port range check • DNS records and reverse DNS • HTTP check and HTTP headers • SSL/TLS certificate check • subnet calculator • IP info • Wake-on-LAN Scans and saved results stay local on your device. Public IP and IP info lookups use HTTPS requests to external services only when you start them. Network Radar Ultra is made for people who want to understand their WiFi without a command line, expert knowledge, or complicated network tools.
