How do I sign in to my account? March 27, 2019 20:03 Updated Follow There is no Tactus Therapy account needed to use our apps. You do need an account with Apple or Google to be able to download our apps from their app stores. Related articles I bought an app, and it hasn't downloaded or is stuck downloading. What should I do? Are there references for your apps? What is the evidence behind them? Why can't I send email from the app? I got a new device. How do I get my apps back? Can I share an app I've bought with another family member?
