No, unfortunately it does not work with phones who are not registered with AppStore or Google Play Store. Some cheaper phones also do not have the correct specs to work the goniometer on the app. To test if your phone will be suitable, download the free app Setsquare or iSetsquare and test if the goniometer is able to measure range in both the vertical and horizontal planes. If not, it means that your phone will not be able to use the Lyno app which is essential for our assessments.
