AI Food Scale, Tape Measure
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Primo Scale turns your phone into a professional measurement toolkit. Point the camera, tap the shutter, and AI does the rest. Four powerful modes in one app: weigh objects, measure dimensions, count items, and scan food for calories - no physical scale, ruler, or counter required.
Powered by Google Gemini and enhanced by LiDAR on iPhone Pro models, Primo Scale delivers results you can trust, instantly.
== FOUR MODES, ONE APP ==
SCALE - Digital Gram Scale
Weigh anything in grams, ounces, or pounds. Perfect for baking ingredients, jewelry, coffee, spices, and small packages. Get a min/max weight range with AI reasoning. A pocket food scale and kitchen scale in one.
MEASURE - AI Tape Measure & Ruler
Capture width, height, and depth of any object in seconds. LiDAR-assisted measurements on supported iPhones for high accuracy. Switch between metric and imperial units. A tape measure and ruler app in your pocket.
COUNTER - Pill, Coin & Object Counter
Count coins, pills, nuts, bolts, or any similar items in a single photo. Ideal for inventory, pharmacy stock, crafts, and DIY projects. A fast pill counter and coin counter app.
CALORIE - Food Scanner, Calorie & Macro Tracker
Identify meals and get total calories plus macros (protein, fat, carbs, fiber) backed by the USDA nutrition database. Perfect for diet tracking and weight tracking without manual logging. Works as a nutrition tracker, calorie tracker, meal tracker, and macro tracker.
== WHO IT'S FOR ==

== WHY PRIMO SCALE ==
- All-in-one measurement app: scale, ruler, counter, and calorie scanner

== HOW IT WORKS ==
1. Choose a mode: Scale, Measure, Counter, or Calorie.
2. Point the camera at the object or meal.
3. Tap the shutter - the scan line animates, then AI processes the image.
4. Review the result with reasoning and save it to history.
== A POCKET LAB ==
Stop guessing weight, size, or calories. Primo Scale replaces a drawer full of kitchen scales, tape measures, ring sizers, pill counters, and calorie apps with one camera-first tool. Capture once, get exact numbers.
