FoldMetry
Read full descriptionHide full description
Open your iPhone Duo. See the angle at a glance. FoldMetry puts the current hinge angle front and center. The number moves as your device opens and closes, with a clean display that stays out of your way. Have a position in mind? Set a target angle and feel a gentle tap when you reach it. Save more than one for the angles you use often. The app follows your device’s Light or Dark appearance, and measurements stay on your device. All measuring features are free. If FoldMetry earns a spot in your day, you can leave a one-time tip to support its independent development. Tips don’t unlock extra features. Hinge angle measurement is available only on iPhone Duo. Other iPhones and iPad can view device support information but cannot measure hinge angles.
WafoNavi

WafoNavi is an unofficial fan app that shows where you are in your PC game on an iPhone or iPad map, in real time. ■ How it works - The WafoNavi addon draws a tiny color block in the corner of your game screen. - The PC program reads that block and sends your position. It never reads game memory or presses keys for you. - Scan the QR code on the PC screen with the app to connect instantly. ■ Features - Live position, facing arrow, and trail - Zone maps built from the game files on your own PC (sent automatically over the same Wi-Fi) - Zone browsing and zoom, search for vendors, materials and zones, with route guidance - Distance traveled: this session, total, and by type (walk, run, swim, mount, flight) - Per-character travel history and weekly/monthly distance rankings (with sign-in) - Korean and English, light and dark themes ■ What you need - The WafoNavi PC program and addon on Windows or Mac (see https://volab.kr/wafonavi/) - Sign-in is optional. Viewing the map works without an account. - To look around without a PC, tap "Try without a PC" on the first screen. WafoNavi is an unofficial fan project and is not affiliated with the game's publisher.

Verdict
The clearest difference is in-app purchases: WafoNavi at none against FoldMetry's 1. WafoNavi also leads on iOS requirement (15.0 vs 27.1). FoldMetry's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
