Your face isn't fixed. Hexum scans it, scores it, and builds a personalized ascension protocol — then rebuilds that protocol every time you rescan. Most "face rating" apps hand you a number and a shrug. Hexum gives you a precise measurement and a plan that adapts as you do. HOW IT WORKS Scan — Guided capture keeps your lighting and angle consistent, every time. Score — Six core metrics, an Overall Score, and your percentile ranking. Ascend — A structured protocol built from your exact results: facial exercises, mewing, neck and posture work, skincare, and nutrition — sequenced into progressive blocks. Rescan — Watch your metrics move, then unlock your next block. As your face changes, your plan changes with it. WHAT HEXUM MEASURES — Facial Symmetry — Jawline Definition — Skin Quality — Facial Harmony — Cheekbone Structure — Improvement Potential YOUR PROTOCOL Not a generic checklist. If your scan flags your jawline as your biggest opportunity, your protocol emphasizes the work that targets it — down to the daily task. It unfolds in three blocks: Foundation — Lock in the daily habits everything builds on: posture, baseline facial activation, skincare, and nutrition. Activation — Targeted resistance work and intensified routines that drive visible structural change. Refinement — Advanced technique and consolidation that make your gains stick. Each block unlocks as you rescan. Your metrics have moved — so your next block is built from where you are now, not where you started. WHY HEXUM IS DIFFERENT Most appearance apps are built around an opinion. Hexum is built around a measurement — grounded in 40+ peer-reviewed studies in facial aesthetics — and a protocol that traces back to your specific results. Scan your face. See your score.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Hexum sells 2 in-app purchases, starting at $9.99 per 7 days and BoulderBuilder sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
BoulderBuilder holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Hexum has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Hexum ships an update fortnightly, BoulderBuilder every 8 days. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
