100% on-device · iPhone & iPad
Mog War turns a single photo into 18 geometric measurements, an annotated overlay showing exactly what was measured, and a 0-10 symmetry index. No account, no subscription, and no photo ever uploaded.
How it works
No sign-up, no upload, no waiting on a server. Everything happens on your device.
A straight-on shot in even light gives the most consistent readout.
Apple's Vision framework locates 76+ facial landmark points on device.
Distances, ratios and angles are computed and compared to stated targets.
Geometry is drawn onto your photo so you can see exactly what was measured.
What it measures
Tap any metric in the app to see what it means, how it's measured and the exact target range it's scored against. Nothing is a black box.
The golden ratio is deliberately not used, because a literal 1.618 target scores almost every real face poorly. The face length-to-width target is 1.45, and the app tells you so.
The honest part
Most apps in this category imply their number means more than it does. Here is the published research behind the choices Mog War makes, including the ones that made it score people less flatteringly.
A 2024 review in Maxillofacial Plastic and Reconstructive Surgery concludes there is “no convincing evidence that the golden ratio is linked to idealized human proportions or facial beauty.” When researchers measured which proportions people actually prefer, the answer landed near the average face, not 1.618. That's why our target is 1.45.
Shape analysis of healthy young adults found roughly a third of measured facial distances were asymmetric in women and around one in eight in men. Asymmetry is the normal human condition, not a flaw. A large British cohort study of 4,732 people also found facial asymmetry was not associated with childhood health.
A selfie taken at about 12 inches inflates apparent nose size by roughly 30%, and smartphone photos at that distance stretch the midface by around 18% compared with a distant shot. This is exactly why the app rejects turned, tilted or too-distant photos before measuring, and why re-measuring in similar conditions matters.
Compared against direct physical measurement, only 7 of 10 standard facial measurements are reliable from a 2D photo, and jaw and cheekbone widths are among the least accurate. Those are measurements this app computes, so treat the inch values as approximate. The ratios are far steadier than the absolute sizes.
To be even-handed: symmetry does have a measurable link to attractiveness ratings in the research literature. But it is one modest factor among many, and its size depends heavily on how the study was run. Mog War is a way to see the geometry of your own face clearly. It isn't a verdict on you.
Why it's different
Mog War doesn't hold anything back. There is nothing to unlock.

What went wrong with face apps
These are the complaints that fill the reviews of the popular face-rating apps. None of them are hard problems. They are business-model decisions.
Several of the best known face apps send your photo to a general-purpose AI model and ask it for a score. Fortune reported this of the category leader, and some competitors name a third-party model directly in their own privacy policies. A language model is not a ruler.
What we do: the measuring is arithmetic. Distances, ratios and angles between landmark points, compared against numbers we publish. There is no model deciding how you look.
Because those models are probabilistic, the score moves when nothing else did. Re-scan the identical photo and it can come back different. It is the single most common complaint in the category, and it is fatal for something claiming to measure you.
What we do: the same photo always produces exactly the same result. When your number changes, something in the photo changed, and that is information you can actually use.
Cloud analysis means your photo is uploaded, processed remotely and retained, commonly for a week to a month. Facial geometry is sensitive biometric data, and once it has left your phone you are trusting a promise instead of a fact.
What we do: nothing is uploaded, because there is no server to upload to. Turn on airplane mode and the app still works exactly the same.
The familiar pattern: take the photo, watch the scan animation, then find the number hidden behind a subscription of roughly four to ten dollars a week, or an invite wall asking you to recruit friends first.
What we do: you see everything, immediately, free. Running on your own device costs us nothing per scan, so there is nothing to recoup and nothing to lock.
In the app
Measure again over time and watch your readout as a trend line, with an optional weekly reminder to re-measure in similar conditions.
Put two readouts side by side and see a measurement similarity percentage, plus a metric-by-metric breakdown of where they differ.
Tap any measurement to read what it means, how it's calculated and and the target range it's compared against, in plain language.
Export your annotated readout in four formats sized for Stories, feed posts, X or a clean 4:5. Each one carries a scannable link back to the app.
On supported iPhones, Apple Intelligence turns your numbers into a friendly readout on device, and it never changes the maths.
Past analyses are stored in the app and nowhere else. Delete any one of them, or all of them, whenever you like.
Privacy
Analysis runs entirely on device with Apple's Vision framework. There is no server, no account and no analytics on your images. Mog War works in airplane mode, which is the simplest proof there is.
Photos are never transmitted, shared or sold. There is nowhere for them to go.
No email, no sign-in, no profile. Open the app and it works.
Analyses live in the app until you remove them, and removing the app removes everything.
FAQ
Yes. Every feature is free, with no subscription, no trial and no account. There is an optional tip you can leave through the App Store, but it unlocks nothing, because nothing in the app is locked.
No. Analysis runs entirely on your iPhone using Apple's Vision framework. Photos are never uploaded, never shared and never sent to a server. They stay on your device until you delete them.
Facial landmarks are detected on device, then 18 measurements (facial thirds and fifths, face length-to-width ratio, jaw angle, canthal tilt, left/right deviation and more) are each compared against a stated target. The overall index is a weighted average: symmetry 30%, proportions 25%, harmony 20%, thirds and fifths 15%, angles 10%. Every target is published inside the app.
Yes. The scoring is deterministic geometry, not a language model, so the same photo always produces the same result. Different photos of the same person will differ, because lighting, angle, expression and distance all change the measurements.
No. A literal golden ratio target of 1.618 scores almost every real face poorly, so the face length-to-width target is 1.45. The app documents this along with every other target it uses.
No. Mog War is an educational and entertainment tool for exploring facial geometry. It is not a medical, clinical or scientific assessment, and results vary with photo conditions.
An iPhone or iPad running iOS 26.4 or later. The plain-language insight feature additionally requires a device with Apple Intelligence, and the app works fully without it.
