Outages
Drippy pings a host you choose and notices when replies stop. Turn on Notify on outages, network and public IP changes in Settings to hear about it as it happens.
Scheduled speed tests
Run a speed test every hour or every few hours and keep the results. That's a record of what your provider actually delivered at different times of day. Networks you've marked as metered are skipped, so tests don't use hotspot data.
Public IP and network changes
A new public IP often means the modem reconnected, and a network change means your Mac switched Wi-Fi or fell back to a hotspot. Drippy notices both.
Traffic alerts
Set a speed and a duration, and Drippy tells you when traffic stays above it, such as more than 5 MB/s for 10 minutes. It's an easy way to catch a large download you didn't start.
Questions
Do speed tests use a lot of data?
Each test uses tens to hundreds of MB depending on your speed, which is why Drippy skips metered networks.
Can I see why the Wi-Fi keeps dropping?
Drippy tells you when and how often. Pinging your router and a public server at the same time shows whether it's the Wi-Fi or your provider.
