@jlo5544 You can set up your phone's health app with information about you that will allow your phone's GPS to estimate your distance travelled and divide that by the average stride length you enter for your personal date in that section of the app. If your phone says the GPS says you walked 2 miles, and your average stride length, even with a walker, is about 18", then it divides the miles, converted to inches, by 18 for that stride length, and you'll get a number of steps.

Really, though, in the final analysis, it isn't the steps that are so important, although they can give you a handy reference for how far you have walked that day. Instead, it's the total distance you move your body because THAT is where the energy expenditure adds up. It costs you calories to move!

If you need help, find someone who can get a decent health/fitness app onto your smart phone and then set it up with information you don't mind the app people knowing about. From there, have the app automatically sense your movement, and when you check it late in the evening, you'll get the information displayed that tells you how active you have been, how many steps it took to be that active, and even tell you how many calories you expended. It will also probably provide you with a small graphic map of your route!

@jlo5544 Here is an answer from the internet. Strapping your phone to your ankle is a solution and accurate way of counting steps, though other measurements (such as heart rate) may not be as accurate). Here is an article to discuss how the ankle placement alters the watch's readings: https://www.simplymac.com/apple-watch/so-many-people-are-wearing-their-apple-watch-on-their-ankle-for-step-tracking-that-it-has-become-a-trend
