NetSamurai is the only one of these five apps whose App Store listing describes checking your devices for security weaknesses without extra hardware, matching them against known vulnerabilities and explaining each fix. iNet matches it on privacy; Fing, WiFiman and Network Analyzer offer more speed-test, Wi-Fi and diagnostic tools.

Checked on 26 October 2026 against each app's US App Store listing (Fing, iNet, WiFiman, Network Analyzer). "Not listed" means the feature isn't mentioned in that app's App Store description, not that it can never do it. Privacy labels are self-reported by each developer and describe data that "may" be collected. Apps change, so check the current listing before you decide. If something here is out of date, email support@netsamuraiapp.com and it will be corrected.

Why people choose NetSamurai
- It answers "is anything a problem?" Findings for Telnet, SMBv1, unencrypted login pages, outdated TLS, UPnP and more, from free Quick checks.
- Known exploited flaws. Software versions and 42 router, camera and NAS models are matched against reviewed CVEs and CISA's KEV catalog, reported as "potentially affected", never overstated.
- Plain-language fixes. Each finding says what was seen, why it matters, what's unknown and what to change, then a recheck confirms it.
- Private. No account, no analytics, no ads; results stay on your device.
When another app may suit you better
- Fing: if you want speed tests, ISP statistics, or blocking and parental controls with a Fingbox.
- iNet: if you mainly want Wake on LAN, remote Mac control, SSH shortcuts or a Bonjour monitor.
- WiFiman: if you want speed tests, Wi-Fi channel and signal analysis, or you run UniFi equipment.
- Network Analyzer: if you want a free full-range port scanner, whois, IPv6 tools or detailed DNS queries.
Comparison questions
What is the best network scanner app for iPhone?
It depends on what you need. For finding security weaknesses on your own network, NetSamurai is built for it: it checks devices for risky services, matches software and device models against known vulnerabilities, and explains how to fix each finding, with no account and no data collected. Fing is strong on device recognition, speed tests and, with a Fingbox, blocking and parental controls. iNet is a private, one-time-purchase scanner with Wake on LAN. WiFiman is free and focused on Wi-Fi performance and Ubiquiti gear. Network Analyzer is a compact free toolkit with a full port scanner, whois and DNS tools.
Is NetSamurai a good alternative to Fing?
Yes, if your main question is whether anything on your network is a security problem. NetSamurai runs its security checks from the iPhone or iPad without extra hardware, while Fing's listing places network vulnerability analysis among Fingbox features. NetSamurai collects no data; Fing's privacy label lists several kinds of data not linked to you. Fing remains the better pick for speed tests, ISP statistics and device blocking with a Fingbox.
Which network scanner apps check for vulnerabilities?
Among NetSamurai, Fing, iNet, WiFiman and Network Analyzer, only NetSamurai's App Store listing describes checking devices for security weaknesses without extra hardware: risky services such as Telnet and SMBv1, unencrypted login pages, outdated TLS, and CVEs including CISA's Known Exploited Vulnerabilities. Fing lists network vulnerability analysis as a feature of its Fingbox hardware. The others offer device lists and, in some cases, port scanning.
Which network scanner apps don't collect data?
NetSamurai collects no data and has no account or analytics. iNet's App Store privacy label also says Data Not Collected. Fing, WiFiman and Network Analyzer list some data collected but not linked to your identity, such as usage data and diagnostics.
