After the intial 24 hour free trial you do not have access to the app, unless you pay for it. As I liked the app, and was very straight forward to use, I paid the subscription fee, which are great low fees to suit brands on a tighter budget, but I did not get access. When I contacted them, the said it was shopify causing the technical issue. I have never been able to access the app from my phone either, I have to go on my lap top. I was told they could not help me with this and to speak to shopify. While they were responsive about refunds, 24 hours later, I still have had zero updates about the technical issue over access. Otherwise, it would have been a useful app, the only downside is that email notifications sent to customers comes from their email address, so customers may not be aware the email is from you and or view it as spam.
