This app was made by Hopebest Limited. It can help you measure how steep the slope of a mountain/trail is. Simply adjust your phone so that it is parallel to the slope you are on and it'll let you know how steep/the angle of the slope. An Inclinometer app is an invaluable digital tool designed to measure angles of slope, elevation, or inclination of an object with respect to gravity. Originally developed for geology and engineering purposes, the utility of this app has expanded to various fields including construction, automotive, and even smartphone photography. Using the internal sensors of a device, such as gyroscopes and accelerometers, the app offers a high degree of accuracy in measuring angles, making complex traditional tools like physical inclinometers or spirit levels nearly obsolete in everyday use. The interface of an Inclinometer app is typically user-friendly and intuitive. Upon opening the app, users can calibrate their device against a known flat surface to ensure precise measurements. The main display then clearly shows the angle measurements, often in degrees. In essence, an Inclinometer app transforms a smartphone or tablet into a multifunctional measurement tool, combining convenience, precision, and versatility. This makes it an essential digital companion for both professionals and hobbyists who require accurate inclination readings in their work or daily life.

Verdict
The clearest difference is ads: Opti Clinometer at none against Offline Inclinometer's shown. Opti Clinometer also leads on update cadence (every 2 days vs monthly). Offline Inclinometer's advantage is device support (3 vs 1) and iOS requirement (14.2 vs 17.0). On price and in-app purchases there is nothing between them.
