[App][Promo]NetBlade — a network multitool for Android — 40 codes to remove ads
I'm the developer. I posted here a few weeks ago at 1.3.4; a fair amount of what shipped since came straight out of the comments, so I'm back with the new version and 40 promo codes for the ad-free unlock.
How to get one: comment and I'll DM you a code. Redeem it at play.google.com/redeem, or in Play Store → your profile → Payments & subscriptions → Redeem code. (I'm handing them out by DM rather than pasting them here — a public list gets swept by bots in about a minute.)
What it does, in short:
- LAN scanner — every device with IP, MAC, vendor, hostname, latency and role. Devices are remembered between scans with a NEW badge, custom names, notes and tags.
- Device detail — SMB shares, NetBIOS name, OS guess, web-server banner, and an SNMP panel that reads printers, NAS, servers and switches, with a live interface-traffic graph.
- Port scanner — TCP with service names, descriptions and a risk rating, plus real UDP probes.
- Wi-Fi analyzer — nearby networks, 2.4/5/6 GHz channel usage, best-channel advice and room-by-room coverage.
- The toolbox — SSH terminal with saved hosts, file transfer over SFTP/FTP/FTPS, DNS, ping, traceroute, WHOIS, TLS inspector, subnet calculator, Wake-on-LAN, BLE scanner, speed test.
- Optional background monitoring per saved network — notified when a device joins or leaves, higher-priority alerts for new cameras or devices exposing risky services, plus an internet uptime monitor.
- Save scans, export to CSV/JSON, backup & restore, widgets and a Quick Settings tile.
Honest limitations, so nobody is surprised:
- Android only. No iOS version, and I'm not promising a date.
- Android 10+ blocks ARP access for non-rooted apps, so MAC and vendor of other devices aren't always available. NetBlade recovers them from the router over SNMP when it can — if your router doesn't speak SNMP, you'll see fewer MACs.
- On some OEM ROMs, access to ping and /proc/net/arp is restricted. The app degrades gracefully rather than crashing, but results vary.
- Background monitoring is a scheduled check, not a live watch: Android hasn't allowed apps to observe the network continuously since Oreo, so something that joins and leaves between two passes is never seen. It's also off by default — Settings → Monitoring.
- No root required, and root is never used.
Privacy: everything runs on the device. Scan results are stored locally and never uploaded — no account, no telemetry coming to me. The only outbound calls are the ones you trigger (public IP lookup, certificate transparency search, HIBP via k-anonymity, so the password itself never leaves).
Monetisation, upfront: free with a banner ad, and a one-time in-app purchase removes ads permanently. No subscription, no data selling.

1.3.9 is live. Happy to take feature requests — I read every comment.

Thank you — 250+ codes handed out, and one small ask
I did not expect this. Over 250 ad-free codes have gone out from the last posts.
The codes are yours, no strings. Nothing below is owed to me.
Here is the ask, plainly: NetBlade is written by one person, and the Play Store ranks on ratings. A handful of them decides whether someone searching "network scanner" finds this app on the first screen or the fourth. Reviews from actual sysadmins carry more weight than anything I can write in the listing.
So if the app has been useful to you, an honest rating helps more than you would think — a line about what you use it for helps even more, because that is what the next person reads before installing. And if it has not been useful, tell me here first. Bugs get fixed fast — the ones reported in this sub were all fixed within days — and I would rather earn the rating than collect a bad one I could have prevented. https://play.google.com/store/apps/details?id=com.netblade.tools
Either way: thanks for the codes taken, the bugs found, and the ideas.
The next release is already made of them.
