Angle Meter lets you measure the angle or slope. Note that you will be able to measure a variety of slope forms. You can choose to directly measure the surface by the second mode, which makes it relatively easy to measure up,or to measure the angle of the target away a short distance away from you after kilo meter. By measuring the angle from the camera aperture. This is a reference line, respectively, and the angles are measured while the display on your phone continuously. You also can take what you measure by showing the angle to keep a check on it later. Featured: 1) Clean and minimal UI 2) Real time display angle value reference by horizontal axis. 3) 2 mode for using(Horizontal Mode and Vertical Mode ). 4) Support measure angles with the camera mode. 4.1) you can take screen short can be a target for record store at a later time. 5) Support the ability to measure the angle from the image. 6) Graphics Animation display related by mode. 7) Display 0 to 90 degree reference by horizontal axis. 8) Calibrate option for accuracy. 9) Support Level Meter allows you to measure the degree of tilt in the vertical plane and can take many forms. The measurements in each axis is locked to the screen, still more easy to measure. 10) There are various UI language menus to choose from. 11) Supports both dark and light themes.
Goniometer

Measure joint range of motion with your phone. Goniometer turns your device's motion sensor into a digital goniometer, so you can track knee, elbow, shoulder, hip, ankle, wrist and neck mobility anywhere — at the clinic, the gym, or at home. Pick the joint and motion you're testing, lay the phone flat along the limb, tap Tare to zero at the neutral position, then move through the motion and capture the ends. The app shows your range of motion in degrees and as a percentage of the normal range for that joint. WHAT YOU GET • Digital goniometer — live joint angle from the phone's accelerometer. • Tare to neutral — zero at the limb's anatomical-zero so you read true movement, not gravity. • Capture min and max — record both ends of the motion to compute ROM automatically. • Measured vs normal — see your ROM next to typical adult values, with a percent-of-normal readout. • Many joints — knee, elbow, shoulder, hip, ankle, wrist flexion and extension, and neck. • Normal ROM reference — a built-in table of typical adult active range-of-motion values. • Step-by-step guide — clear instructions and accuracy tips for repeatable measurements. WHO IT'S FOR Physical therapy and rehab patients tracking recovery, PTs and trainers, yoga and mobility enthusiasts, and anyone curious about their flexibility. A NOTE ON ACCURACY Readings depend on your phone's sensor and how it's aligned to the limb. This app is a measurement aid for fitness and education — it is not a medical device and does not diagnose. Consult a qualified clinician for assessment.

Verdict
The clearest difference is update cadence: Goniometer at every 4 days against Angle Meter's every 4 months. Goniometer also leads on iOS requirement (16.4 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
