Every StallWise plan already includes the medication clearance calculator. Sign in to StallWise (or to the ShowSafe Pro app with your StallWise login) and it is there; you do not need a separate ShowSafe Pro subscription.
Moving from ShowSafe Pro to a StallWise plan - Subscribed on the web: open More > Settings > View Plan > Manage billing and switch to the StallWise plan you want. It replaces ShowSafe Pro, so you are never billed twice. - Subscribed on iPhone: cancel ShowSafe Pro on your iPhone (Settings > your name > Subscriptions). When the paid period ends, sign in on the web and choose a StallWise plan. Write to us from this page if you need to switch sooner.
If you were ever charged for both, write to us from this page and we will refund one.
