Last update not working on iPhone 6s – Argus: Step and GPS Tracker Review

After last update this app no longer works on iPhone, just freezes up and closes. Have bee using this app for years for steps, water, meds, blood pressure, blood sugar, ect. Contacted website with no response from them. I hate to have to ditch this app but .... it needs glitches fixed so it works well again and take out the premium version screen that pops up for those who will never pay a monthly charge for the app.
