Foldometer vs Fold Counter

Your fold, measured. Open iPhone Duo and Foldometer turns its hinge into a precision instrument. Watch the two halves move on screen as you open and close it, read the exact angle between the displays, and feel a gentle tap when you land on a right angle or lie perfectly flat. It's the most fun way to see what your new foldable can do. Not on a foldable? Foldometer is a beautiful level, protractor, slope meter and camera angle finder for every iPhone and iPad. HINGE (IPHONE DUO) • The live angle between the two displays, from closed to fully open • An animated side view of your device that follows the hinge • Stand presets for Easel, Upright, Video call, Laptop and Reading, or save your own, with a tap when you reach them • Set a zero at any position to measure how far the hinge moves • Record the angle over time, then see a chart with the range and peak speed, and share it as an image or CSV FOLD GAUGE (IPHONE DUO) • Rest one half on a surface and lay the other against a second surface • Foldometer combines the hinge with the motion sensors to read each half's angle from horizontal, even when the first surface isn't level LEVEL • Stand iPhone on an edge to read its tilt, shown to a tenth of a degree • Lay it flat and it becomes a bubble level for any surface • Turn it on its side and the reading keeps counting, with "2.4° from level" right where you need it • Hold iPhone against one surface, tap Set Zero, then rotate to the next to read the angle between them SLOPE AND PITCH • Show any slope in degrees, percent grade, millimetres per metre, inches per foot or roof pitch • Set a target such as a 2% patio fall, a ¼ in/ft waste pipe, a 1:12 ramp or a 6/12 roof, and feel a tap when you hit it CAMERA • Measure angles you can't reach, like a roof line or a leaning post, by lining up arms over the camera view • Slopes read against the true horizon from the motion sensors, even if iPhone is tilted • Freeze the frame to fine-tune PROTRACTOR • Two draggable arms on a full 360° scale, with a tick of haptic feedback for every degree • Tap the reading to flip to the reflex angle PRECISION • Flip calibration: take a reading, turn iPhone around in place, take another. Calibrating on its back also corrects for the camera bump or a case. • Auto-Hold freezes the reading the moment iPhone comes to rest, so you can read it after moving away LOG AND WIDGETS • Save any reading with one tap, add notes like "Garage roof pitch", and export everything as CSV • Home Screen and Lock Screen widgets show your fold angle and newest reading DESIGNED FOR APPLE PLATFORMS • Built for iPhone Duo's displays: toolbars and tabs along the side, and layouts that adapt as you fold • Liquid Glass controls, light and dark appearances, and a layered icon • VoiceOver, Dynamic Type and Reduce Motion support • No account, no ads, no tracking. Camera images are never recorded or stored, and your readings stay on your device. A NOTE ON ACCURACY Readings depend on your device's sensors and how it's held. On iPhone Duo, iOS reports the hinge angle and decides how often it updates. Foldometer is a general measuring tool, not a medical or safety device.

How often do you really fold your phone? Fold Counter counts every fold and unfold of your foldable iPhone, turns it into clear statistics and shows you how much of your hinge's estimated life you've already used. COUNTS LIVE, CATCHES UP LATER While the app is open, it reads the system hinge sensor and counts every fold and unfold in real time. Folded it while the app was closed? When you come back, Fold Counter notices the change and records it as an "inferred" fold, so your history stays complete. You can also log folds manually at any time. OPTIONAL: COUNT WITH SHORTCUTS Fold Counter adds two actions to Apple's Shortcuts app: "Count Fold" and "Count Unfold". They run in the background without opening the app. Set up a personal automation once – Shortcuts → Automation → + → "Opened or Closed" → "When iPhone is Closed" → tap Search, type "Fold Counter" and tap "Count Fold" (optionally a second one with Opened → "Count Unfold") – and every close and open of your foldable iPhone is counted, even when Fold Counter isn't running. No location, no extra battery. Settings → "Set up step by step" walks you through it with a screenshot and shows a green check as soon as the automation works. Requires iOS 27.2 or later. STATISTICS THAT TELL A STORY • Folds per day and your total over time • Time spent folded, half open and unfolded • Opening angles: tent, laptop or flat • How long your phone usually stays unfolded • Time of day, weekdays and a weekday × hour heatmap • Where you fold: a map of your fold spots and your top 3 places (optional) • Full history of every recorded fold QUESTIONS, ANSWERED The Questions tab turns your data into plain-language insights: • When do you fold the most? • Is today busier than usual? • Which weekday is your folding day? • How long does it stay unfolded? • Do you fold more on weekends? • How long would the hinge last at this pace? • Where do you fold the most? ICLOUD BACKUP & STARTING COUNT Signed in to iCloud? Your folds sync to your private iCloud, so your counts survive a reinstall or a new iPhone. Folded long before installing the app? Enter those folds and unfolds as a starting count in Settings – they're added to your totals, hinge lifetime and widgets. Today shows your folds total and unfolds total at a glance. ESTIMATED HINGE LIFETIME Set the rated number of folds (75,000 by default, adjustable) and see what percentage you've used and roughly how long your hinge will last at your current pace. WIDGETS & SHORTCUTS Keep your fold count and estimated lifetime on your Home Screen and Lock Screen. Log a fold from Shortcuts or Spotlight anytime. PRIVATE BY DESIGN No account, no tracking, no ads. Your data is stored on your device and, if you use iCloud, in your private iCloud database, which only you can access – the developer never sees it. Location is only used if you turn on "Record fold locations" – fold locations are stored on your device, and only place names are looked up via Apple Maps. MORE • English, German, French, Italian, Spanish, Portuguese and Korean • Light and dark mode REQUIREMENTS Automatic counting requires a foldable iPhone with a hinge sensor. On other iPhones you can log folds manually and explore every statistic with sample data (Settings → Load sample data). Get to know your fold habits — download Fold Counter today.
