Android runs in software, free, thousands of phones at once, so that is where every published number comes from. An iPhone cannot. It needs real hardware, a Mac, a signed developer build and a harness that does not lie to you. So nobody measures it.
See the results →Every task runs on a physical iPhone. Nothing is simulated, and no human decides whether a run passed.
| Model | Pass rate | Passed | Avg steps | Avg time | Cost/task |
|---|---|---|---|---|---|
| Claude Sonnet 5 | 95.9% | 71/74 | 6.9 | 55s | $0.172 |
A task passes only if the phone itself ends in the required state. What the agent says it did counts for nothing: an agent that reports “I have enabled that setting” and an agent that enabled it are different things, and only the second one passes.
A pass rate says how often a model succeeded. This says at what. Each capability is isolated by at least one short task, so a failure names a missing skill instead of pointing vaguely at a long task that went wrong somewhere in the middle.
| Capability | What it takes | Tasks | Passed |
|---|---|---|---|
app-resolve | turning a spoken app name into the right bundle id | 2 | 2/2 |
back | leaving a screen when the way out has no label | 1 | 1/1 |
context-menu | holding a link until its preview menu opens | 1 | 1/1 |
date-navigate | moving around a calendar rather than a list | 1 | 1/1 |
edge-gesture | a swipe that must start at y=0, off the drawn screen | 1 | 0/1 |
hierarchy | going up, not just down, through nested screens | 5 | 5/5 |
icon-only-control | a control with a glyph and no text to match on | 1 | 1/1 |
lifecycle | launching, backgrounding and returning to an app | 3 | 3/3 |
picker | reaching a spinning wheel | 1 | 1/1 |
picker-multi | addressing the right column when several are side by side | 1 | 1/1 |
picker-set | turning a wheel to a value, which a swipe cannot do | 3 | 3/3 |
precise-taps | hitting small targets laid out in a grid | 2 | 2/2 |
read-field | reading a value back off the screen, not guessing it | 3 | 3/3 |
recover | noticing the wrong app is open and fixing it | 2 | 2/2 |
scroll-end | reaching something below the fold | 2 | 2/2 |
search-then-act | using an app's own search instead of navigating | 6 | 6/6 |
slider | reaching a continuous control | 1 | 1/1 |
switch | reading and setting a toggle | 1 | 1/1 |
tabbar | moving between tabs in an unfamiliar app | 4 | 4/4 |
text-exact | typing a string that must match character for character | 2 | 2/2 |
text-long | typing something long enough for autocorrect to interfere | 1 | 1/1 |
text-select | selecting text that is already on screen | 1 | 1/1 |
Three parts. The first and the third involve no model at all, which is what makes a score reproducible.
Deterministic steps, no model involved, so every attempt starts identically.
The agent sees an accessibility tree and a screenshot, and acts with taps, typing, gestures and picker wheels.
Assertions read the device directly and decide pass or fail. The agent never sees them.

A Mac, an iPhone, a cable and an Apple developer account. The harness builds and installs the automation runner onto the phone for you.
git clone https://github.com/blomega/phoneshell
cd phoneshell
bin/phoneshell doctor # tells you exactly what is missing
bin/phoneshell setup # builds and installs the runner on your iPhone
bin/phoneshell up # brings the bridge up
bin/phoneshell bench --list
bin/phoneshell bench --model claude-sonnet-5The harness is free and open. What breaks it is not your code: it is an iOS point release, an Xcode update or a change in WebDriverAgent, any of which can stop the bridge working on a Tuesday morning. We keep a tested build working and there is a person to call.
Cloud farms give you clean, ephemeral phones. Some things need a real handset: an OTP to a real SIM, a payment through a local wallet, region-locked content, an account with history behind it.
Every published mobile-agent number is Android, because Android runs in software and iOS does not. If you want your model measured on iOS rather than assumed to transfer, the suite above is free to run today.
