Live
What is using your connection — right now.
Every app with its live rate and a minute of history. Helpers fold under their parent, so Arc and its twelve helpers are one row.
Helper grouping
Browser, GPU and renderer helpers count toward the app they belong to.
Nothing slips through
Connections that open and close between two samples are reconciled with your network interface, so totals match what your provider sees.
A tiny companion
The egg in the header sleeps when you're idle, hops under load and sweats on a hotspot.

History

Today, this week, all time.
Per-app totals with a share bar, an hourly chart you can hover, and 7- and 30-day trends. Click any app for its own history and a week-over-week comparison.
Months of history, kilobytes on disk
Samples roll up into minutes, hours and days in a local SQLite file.
Per-app detail
One app's traffic by day and by connection, compared with last week.
Export anytime
All your data as CSV, one click from Settings.
Data plan
Know before the bill does.
Set your monthly allowance and ova tracks it — all traffic for a capped home line, or only the hotspot for a phone plan. You're notified at 80% and 100%.

Monthly data plan
Cap, reset day and what counts — the card shows exactly where you stand.
Hotspot aware
Recognises iPhone and Android tethering and splits today's traffic by connection.
Alerts that matter
A daily limit on metered connections, per-app watch rules, and a heads-up when something uploaded while you were away.
Quiet Mode
Pause iCloud, Time Machine and App Store sync on a hotspot — automatically, if you like.
Everywhere
Not just the menu bar.
ova shows up where you already look.
Desktop widget
Today's usage, top apps and your data plan at a glance.
Siri & Shortcuts
“How much data did I use today?” — answered without opening anything.
Opens at login
Set it once; ova is measuring before you open a browser.
