How to choose
- What do you get back? A single number, a breakdown of metrics, or a plan.
- Is there a routine? Scores help most when they lead to daily actions and a way to rescan.
- Is it honest about limits? Any AI score from one photo is an estimate, and scales like PSL have no official standard.
- What does it cost? Most apps in this category are free to download with a paid subscription.

1. Hexum
Hexum maps 247 facial landmarks from one photo, scores 34 metrics (symmetry, jawline, skin quality, facial thirds, canthal tilt and more), gives an Overall Score from 0 to 100 with a percentile, and builds a daily improvement protocol of about 38 minutes a day. It also has an AI coach and rescans for tracking. It does not output a PSL number. Free to download with a free first scan; Hexum Pro unlocks the rest. iPhone only, iOS 17+.
Best for: people who want measurements, a prioritized list and a daily routine in one app.
2. UMAX
UMAX is one of the best-known looksmaxxing apps. Its App Store listing describes a face scan that produces a PSL-style score, with ratings for areas such as symmetry, canthal tilt and skin quality, plus tips. It is free to download with in-app purchases. Several similarly named Umax and LooksMax apps exist on the App Store, so check the developer before downloading.
Best for: people who specifically want a PSL-style number.
3. FaceKit
FaceKit (“FaceKit: 3D Face Analysis”) describes itself as a 3D face-scanning tool that reports on facial structure and proportions. Its listing focuses on analysis of your face’s geometry rather than a daily improvement routine. It is listed as free in the Utilities category.
Best for: people who mainly want a 3D structural analysis of their face.
4. PSL calculator apps
“PSL calculator” is a category more than a single app. Apps such as PSL Scale, PSLScore and Adonis estimate a score on the 1 to 8 PSL scale from a face photo, and some add a percentile, a list of strengths and weaknesses, or a multi-week plan. Most are free to download with a paid subscription. PSL is an informal forum scale with no official definition, so scores from different apps are not directly comparable. See our PSL calculator guide.
Best for: people who want a PSL-scale number specifically.
5. DailyGlowUp
DailyGlowUp is described in a third-party listing as an app where you upload a photo, the AI analyzes your skin, and you receive scores and a personalized routine, with a subscription required for the full results. We could not confirm its details on the App Store, so check its listing directly.
Best for: people focused on skin and a skincare-style routine.
