The short answer
PSL Scale’s free PSL rating runs in your browser and gives you a starting point without buying an app subscription. Use the Wiki to understand the PSL scale, then choose a focused AI analysis or the complete Face Report only if you want more detail. Paid tools use clearly listed credits.

Understand the scale before you compare the number
A free download does not mean every result inside an app is free. Umax’s official App Store description distinguishes the download from access to analysis results. Check the renewal period and total charge shown on your own purchase screen; offers can differ by region.
PSL Scale separates a free entry point from paid AI interpretation. More importantly, it explains the vocabulary. Read what PSL means and the PSL rating scale before comparing a PSL value with an ordinary score out of ten.
Two services may assign different numbers because they use different scales, image processing and reference rules. A change between apps is not evidence that your face changed. Choose a consistent tool and comparable photographs if you want a useful baseline.

Free PSL Rating
The free PSL rating is the most direct starting point for someone comparing Umax alternatives. Use a clear photo and read the explanation alongside the result, rather than interpreting the number as a universal ranking.
Afterward, investigate one question at a time: symmetry, eye area, jawline or face shape. The broader tool collection makes the result a starting point for exploration instead of the end of the session.
- 01Take one clear photo in even light.
- 02Run the free PSL rating and read the scale explanation.
- 03Choose a feature tool or optional AI report based on the question you still have.
A method you can put in context.
PSL Scale brings together landmark-based measurements, visual AI interpretation and the PSL vocabulary used in facial-aesthetics communities. The scale guide explains the categories and what each score means, so you can connect a result to an established framework.
Geometry describes visible relationships in the image; an AI report interprets the photo. Those outputs serve different purposes. Research considers multiple facial cues and individual preferences, rather than validating one universal beauty formula. A golden-ratio or symmetry result should be read with that limit in mind.
Our AI reports primarily use current-generation OpenAI vision models, with a fallback available when needed. We keep the analysis up to date as the product develops. Modern visual models support detailed explanations alongside measurements. For a useful result, use a consistent photo setup and read the reasoning alongside the score.
For the distinction between measurements and preference, see Little, Jones & DeBruine’s review of facial-attractiveness research. The paper provides background, not validation of PSL Scale or any competing service.
Know what you are paying for.
Free measurement tools are separate from paid AI reports and generated images. The complete Face Report uses 200 credits; a $9.99 Standard pack includes 200 credits and covers one report. A smaller Starter pack costs $5.99 for 80 credits.
For a focused example, one paid Face Symmetry analysis uses 10 credits. Compare the pack you actually need with the feature you plan to use; an allocated per-use credit value is different from the amount charged when you buy a pack. Check current pricing and feature costs before purchase.
Frequently asked questions
Is there a free Umax alternative?
Yes. PSL Scale has a free browser-based PSL rating tool. It also offers optional paid AI analysis, which is separate from the free result.
Is Umax free to use?
Its App Store listing says the app is free to download with in-app purchases, and that analysis results require a subscription. Check the current listing and purchase screen for your region.
Does PSL Scale require a weekly subscription?
No subscription is required for its free tools or credit-based AI reports. Check the pricing page for the pack and credit cost that fit your selected feature.
Why is my PSL score different from an app rating?
A PSL scale and a generic one-to-ten rating are not interchangeable. Photo quality and each service’s scoring rules can also change the result.
