Hi Libbie,
 
I’m very sorry for the delay in our response – the Q&A responses are slow versus contacting our support team.
 
The app is priced according to each country with pricing shown in the Play Store / App Store and more importantly in the app when you arrive at the paywall. We recently moved to a subscription service so that we can align income with the cost of providing the service and fund future development of the app.
 
I hope this helps.
 
Kind regards,
Darren
mySymptoms team.
