WOTools includes some useful tools that will help you while working out: - A timer: simple, easy to use, notifies you when a selected duration is over. - A chronometer: so simple! - A plate calculator: determines which plates to put on each side of a bar given a bar weight. - A reverse calculator: calculates the total weight given a bar weight and a number of plates. - A 1RM calculator (One-rep max): calculates 1RM corresponding to a certain number of reps and a given weight. WOTools is very easy to use and straightforward. Select the timer duration thanks to list of a pre-defined values (that you may customise), or from a wheel. The timer remembers the last duration you selected. Select the sound to be played when the timer is over (25 sounds are available). Modify the bar weight as simply as it is to input the total weight and to calculate which plates to put on each side of a bar, given a set of available plates (that you may customise). 1RM is calculated along with a table of percentages that will be useful for your training program. Choose the algorithm that provides the results that best suit you. Select a picture or a photo of yours to be used as a wallpaper in WOTools. WOTools is compatible with iOS 13 Dark Mode. WOTools works perfectly well without any internet connection.

Goniometer turns your smartphone into a joint range-of-motion measuring tool, designed for physiotherapists and healthcare professionals. Using the device's inertial sensor (IMU), measure the angle of a movement in real time, set the zero in the starting position, then capture the left and right sides to compare. An asymmetry of 10° or more is flagged automatically. Three ways to measure ⢠Motion sensor (IMU) ā lay the phone against the segment and the angle updates live, with its trace. ⢠Angle dial ā a large, clear, centred reading. ⢠On a photo ā place three points (segment, joint, segment) and the angle is computed automatically. Highlights ⢠Real-time measurement and set-to-zero (tare) ⢠Left / right comparison and asymmetry detection (ā„ 10°) ⢠Angle movement trace ⢠Goniometric measurement on a photo ⢠Built-in step-by-step help and FAQ ⢠Available in English, French, German, Spanish, Italian, Dutch, Polish, Greek and Portuguese Goniometer is part of Physia, the clinical software ecosystem developed by Procaryote: rigorous, easy-to-use, privacy-first tools to assess, measure and follow up your patients. Goniometer is a measurement-aid tool for healthcare professionals; it does not replace clinical judgement or a certified medical device.

Verdict
The clearest difference is update cadence: Goniometer at every 5 days against WOTools's every 4 months. Goniometer also leads on iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
