“Where did my 40 GB go?”
Every partition with its mount point and size, and a chart of used space by day — so you can see the exact evening it filled up.
The system monitor for Apple devices
Everything your device knows about itself
Omnistat reads the numbers iOS keeps to itself — every core, every partition, every byte of traffic, every sensor — and puts them on one screen, in your widgets and on your wrist.
Free to use. History, alerts and the speed test are part of Omnistat Pro.

Device
Every spec, one screen
The identity sheet iOS never shows you: what the hardware is, what it is running, and how long it has been up.
- Model, internal name and identifier
- System, build and kernel version
- Boot time and uptime to the minute
- Resolution, scale, refresh rate, brightness
Wi-Fi & cellular
Latency and jitter, not bars
Four bars tell you nothing about a call that stutters. Omnistat measures the connection instead of drawing it.
- Live download and upload, plus data used since boot
- Latency, jitter and DNS lookup time
- Network name, BSSID, signal and security
- IPv4, IPv6, VPN, Low Data Mode, carrier and radio
Performance
Every core, GPU and heat
Where the work is going and what the heat is doing to it, core by core.
- Usage per core, with the user / system / idle split
- Thermal state and how many cores are still online
- Frequency, architecture, caches, physical and logical cores
- GPU name, Metal family, unified memory, ray tracing
Sensors
Live, and in 3D
A model of your device that moves as you move it, with the instruments that feed it underneath.
- Pitch, roll and yaw on a 3D device, plus rotation rate
- A level that adapts when the device is not flat
- Compass and magnetic field strength
- Barometric pressure and relative altitude
History Pro
Your device, day by day
Omnistat samples in the background, so a storage cliff or a battery draining faster than last week is visible before it bites.
- Storage, memory, battery, CPU and traffic, charted
- Day, week, month or year
- Billing periods that follow your own plan dates
- Thermal throttling and active cores recorded over time
Speed test Pro
Your real speed, in seconds
Parallel streams against public endpoints, so the number reflects the line and not one socket — in the unit you picked.
- Download, upload, latency and jitter
- Every run kept, tagged Wi-Fi or cellular
- Trend chart across runs
- Start it from a widget, a Shortcut or Siri
Alerts Pro
Warned before it's a problem
Thresholds you set once, checked while the app runs and during background refreshes.
- Storage below your limit
- Data plan at 80 % and 100 %, counted from your reset day
- Overheating, battery low or fully charged
- Unusual traffic and unusually slow connections
Why people install it
The questions your device won't answer
Settings gives you a pie chart and a percentage. Omnistat gives you the number, where it came from, and what it was doing yesterday.
“Why do my calls stutter?”
Latency, jitter and DNS lookup time on the connection you are actually using. Four bars can look perfect while jitter ruins the call.
“Is my battery getting worse?”
Charge recorded over days and weeks, beside the thermal state and active-core count that explain a bad afternoon.
“Will I blow through my plan?”
Wi-Fi and cellular traffic counted per billing period from your own reset day, with a warning at 80 % and at 100 %.
The read-out
What Omnistat actually reads
Every figure comes from the system itself, refreshed while you watch. Three of them are worth seeing up close.
- 8
- areas, from the processor to the barometer
- 70+
- individual values, all live
- 4
- platforms: iPhone, iPad, Mac, Apple Watch
Network
The numbers behind a bad call
A full signal bar and a stuttering call are perfectly compatible. Omnistat times the connection instead of drawing it: how long a packet takes to come back, how much that varies, and how long a name takes to resolve — on Wi-Fi and on cellular alike.
- Latency
- Jitter
- DNS lookup
- Live throughput
- Data since boot
Performance
Where the work goes, core by core
Fourteen cores, each with its own load, next to the split between your apps and the system — and the thermal state that decides whether all of them are still running. When the phone slows down, this is the screen that says why.
- Usage per core
- User / system / idle
- Thermal state
- Active cores
- GPU & Metal
Sensors
A device that moves as you move yours
The accelerometer, gyroscope, magnetometer and barometer are in your hand already. Omnistat draws them: a 3D model that follows your device in real time, a level that adapts when it is not flat, a compass, and altitude from air pressure.
- Pitch / roll / yaw
- Rotation rate
- Level
- Compass
- Pressure & altitude

Pricing
Free for everything live. Pro for everything over time.
The read-outs, the widgets, the Watch app and the Shortcuts cost nothing. Pro pays for the parts that keep working while the app is closed.

Questions
Before you download
Is Omnistat really free?
Yes. Every live read-out, the widgets, the Apple Watch app and the Shortcuts actions are free and always have been. Omnistat Pro adds history, alerts and the speed test.
What does Omnistat Pro cost?
A monthly or a yearly subscription, each starting with a one-week free trial, or a one-time lifetime unlock. Prices are set per region and shown in the app and on the App Store before you confirm anything.
Do I need an account?
No. There is no sign-up, no login and no profile — Omnistat has no server of its own.
Where does my data go?
Nowhere. Readings, history and speed-test results are written to the app’s own storage on your device and stay there. The privacy policy lists the only things that leave: anonymous usage statistics, crash reports, and the requests the speed test itself has to make.
Why does the app ask for Location?
Because iOS only reveals the name and address of the Wi-Fi network you are on to apps with location access. Your position is never read, stored or transmitted, and refusing simply hides the network name.
Does the background history drain my battery?
It samples during the short background refreshes iOS schedules for the app. There is no continuous process and no background location.
Does it work on Mac and Apple Watch?
Yes. Omnistat runs on iPhone and iPad, as a Mac app, and on Apple Watch with complications showing your iPhone’s storage, battery and memory.
How accurate is the speed test?
It measures against Cloudflare’s public endpoints over several parallel streams, which is how a real download behaves. Every speed test depends on the route and the moment, so treat one run as a sample and the history as the answer.
