What you see
- Daily, weekly and monthly totals, with the top apps for each period.
- Each app's page: its usage over time, the day it was first seen, and the domains it talked to.
- A split by network, so the hotspot and home Wi-Fi don't blur into one number.
- Peak day, peak hour and daily average, and how much of the traffic the top three apps account for.
Unusual activity
Drippy flags apps that are new this week or uploading far more than usual, like "Uploaded 4 GB today, usually 200 MB a day". Turn on notifications for it in Settings.
Keep it or export it
Usage stays on your Mac. Settings › Export usage as CSV saves it to your Downloads folder, ready for a spreadsheet.
Questions
How far back does Drippy keep usage?
Everything since you installed it. History isn't trimmed.
Can I see usage per website?
Per domain, on each app's page: which domains it talked to and how much went to each.
Does it count other devices on my network?
Only if you turn on Watch the router's traffic over UPnP in Settings and your router supports it. Per-app numbers are always this Mac's.
