Wi-Fi Share: Network Toolkit

Slow Wi-Fi, unknown devices on your network, sharing the password with friends — one app handles it.

"Wi-Fi Share: Network Toolkit" turns your Wi-Fi into a QR code guests can scan to connect, and doubles as a home network toolkit: see who's on your Wi-Fi, find out what's slowing it down, inspect website certificates, check whether IPv6 works — 18 tools that used to need technical know-how, now one tap and a clear result. We run no servers of our own; your Wi-Fi passwords stay on your phone.

■ Wi-Fi Sharing (core features, free to use)

• Wi-Fi QR Sharing
