Tools and settings
Work out a subnet
“Subnet calculator” takes an address with a prefix or mask, for example 192.168.1.10/24, typed on the IP keypad. The chips “This device” and “Gateway” fill in your current network. It works for IPv4 and IPv6.
- IPv4: network, broadcast, first and last host, usable hosts, netmask, prefix, wildcard and type (private, public and so on). “Binary” shows the network bits in teal and the host bits in gray.
- “Split into smaller subnets”: pick a longer prefix to see how many subnets you get, their size and their ranges.
- IPv6: the address compressed and expanded, the network, the last address, the prefix, how many /64 subnets fit, and the type.
The number after the slash is how many leading bits are the network part. A /24 means the first three numbers are shared by every device on the network, leaving room for 254 devices.
Pick a private range that won't clash
“Private ranges” lists the address blocks that aren't routed on the internet and what each is for: the three RFC 1918 blocks (10/8, 172.16/12, 192.168/16), carrier-grade NAT (100.64/10) and IPv6 unique local addresses (fd00::/8).
Two sites using the same default range, such as 192.168.1.0/24, can't be joined by a VPN without renumbering one of them. Under “Pick a subnet that won't clash”, choose a block and a size and tap “Pick a subnet”. The app picks one at random that avoids common router, VPN and container defaults and your current network. “Open in subnet calculator” shows its details.
For IPv6, “Generate a /48” creates a random unique local prefix and its first /64, as the standard recommends, so two networks that meet later don't collide.
Keep and compare scans
A saved scan is a snapshot of the Wi-Fi scanner at one spot, with its note. Save one from the scanner's ⋮ menu (“Save scan”). “Saved scans” lists them by date with the note, number of radios, the network you were on, and ⚠ with the count of networks that overlapped yours.
- Tap the pencil to edit a note. The first line of a note becomes the title in reports.
- Tap scans to select them, or “All”. Then “Export” writes them as one report, PDF, Markdown or plain text, oldest first, one section per scan. Pro
- The bin icon deletes the selected scans after asking.
A saved scan keeps the names and ownership as they were when you saved it, so later changes don't alter it.
Save results to a file
Most tools with results have a save icon in the title bar. It offers “Save as PDF”, “Save as Markdown”, “Save as Plain text” and, for tools whose results are a table, “Save as CSV”. You choose the folder (or a cloud drive) in Android's file picker. “Share PDF…” sends a PDF through the share sheet instead. Pro
| Format | Good for |
|---|---|
| Handing a report to someone: printed layout, with charts where the tool has them. | |
| Markdown | Pasting into a ticket, wiki or documentation. |
| Plain text | Email, chat, or anything that doesn't render formatting. |
| CSV | Spreadsheets. |
Some tools have their own formats: the coverage log saves KML, CSV and WiGLE files, the cell survey saves CSV and Markdown, and the HTTPS check saves the certificate chain as a .pem file. Files only leave the phone when you send them somewhere.
Manage access point names
Settings › “AP names” lists every name you've given an access point, as “all radios” of a physical access point or “this radio only”. Tap a name to change it, or the bin icon to delete it. “Delete all names” clears the list after asking.
“Import” and “Export” in the title bar read and write a CSV file with the columns mac,label,scope, where scope is ap (all radios of that access point) or bssid (that radio only). Use it to back up your names, move them to another phone, or prepare them in a spreadsheet. Import is forgiving: it accepts commas, semicolons or tabs, any MAC punctuation, an optional header row and # comments, merges with the names you already have, and reports any lines it skipped. Import and export are free.
Put the connection on your home screen
The SSIDekick widget shows what the start page's readout shows: network name, signal, band, channel and link rate, and, when the widget is tall enough, your IP, gateway and public IP and a traffic chart. Its buttons open “Wi-Fi”, “LAN”, the internet “Check” and “Live” activity in the app; ↻ refreshes it.
Add it from the home screen: long-press › Widgets › SSIDekick. Long-press the widget, or open Settings › “Widget” in the app, to choose how often it refreshes:
- “Every 15 minutes”, “Every 30 minutes” or “Every hour” run quietly in the background.
The widget also refreshes at once when the network changes. It reads only what Android already knows; it doesn't scan or send traffic. Android hides the Wi-Fi network's name from widgets, so the widget shows the name the app last saw, marked with “·”.
Hide tiles you don't use
Tap the “Hide tiles” tile under Settings. The start page switches to choosing mode: tap a tile to hide or show it (hidden tiles are dimmed with an eye mark). Tap “Done” when finished. Hidden tools also leave the Recent row, and a group with no tiles left loses its heading. The “Hide tiles” tile itself can't be hidden, so you can always get them back. Pro
