Beauty and diet in one app. Map your skin, fine-tune your personal color, and log calories & sodium free with a single photo — Rena coaches you from your real data.
Renka - World's First Real 3D Face Scanner
Discover your unique facial features with cutting-edge IR depth sensor technology. Renka is the first app to go beyond simple 2D photo analysis and deliver true 3D facial measurement.
■ Precise 3D Measurement
Your iPhone's IR depth sensor captures your face in real 3D — accurate width, height and surface area that 2D apps can't provide.
■ Face Shape Analysis
Find out your face shape — oval, round, square, heart, oblong, diamond and more — with hairstyle, eyewear and makeup recommendations to match.
■ Plastic Surgery Simulator
Preview eye enlargement, nose augmentation, V-line and more — based on real 3D facial data, not photo-based AI guesswork.
■ Golden Ratio Analysis
See how your facial proportions compare to the golden ratio. We analyze eye spacing, nose ratio, lip ratio, facial thirds, and overall harmony.
■ Symmetry Score
Precisely measure your facial symmetry and understand your left-right balance.
■ Attractiveness Analysis
Get a comprehensive attractiveness score based on golden ratio, symmetry, facial contour, and expression. Includes expression detection!
■ Jawline & Contour Analysis
A contour score from your gonial angle, fWHR and chin angle — plus your jawline type: angular, standard, or soft.
■ Skin Analysis
A skin map visualizing blemishes, pigment and redness, with a 5-axis radar and area care guides.
■ Eye Shape, Nasolabial Line & Dark Circles
Eye tilt, MRD1, nasolabial depth and a dark-circle index — in numbers.
■ AI Beauty Consultation (Rena)
One-on-one consultations with Rena, your AI beauty agent — personalized makeup, hairstyle and skincare advice based on your real measurements.
■ AI Hairstyle & Glasses Try-On
Try AI hairstyles and glasses on your own photo — curated cuts and frames for your face shape, photorealistic in seconds.
■ Swelling Tracking
Track daily changes in facial swelling. Perfect for checking morning puffiness or monitoring the effects of your skincare. Per-area indexes and a heatmap, compared against your baseline.
■ DietCam — free calorie & sodium tracking
Snap (or pick) a food photo to log calories, sodium and glycemic index to Apple Health — free, no limits. Cross-analyze sodium vs. your swelling on one chart, and see how salty meals affect next-day puffiness. On-device AI is fast; ask Rena about tricky dishes or your diet. Now one tap from the main screen.
■ Measurement History
Save your measurements and track changes over time. View your trends in easy-to-read charts.
■ 100-Day Challenge Report
Every 100 days: your changes vs. the last period, all-time trends, and Rena's AI summaries. Preview via the sample report.
■ Personal Color Analysis
Discover your personal color! Now with a much-improved algorithm and Personal Color Precision Fitting (digital draping).
■ Live AR Filter
Turn your camera into a real-time face analysis tool. See your face shape, facial thirds/fifths ratios, and profile angle as live overlays — then record and share in one go.
■ Beauty Selfie
A real-time beauty studio: adjust soft glow, midface, V-line, eye size and nose slimming with sliders, then capture instantly.
