Bought lifetime service. But after upgrading to a new device, the app wouldn't work. Moreover, only received automated responses. And now they write that a lifetime subscription is tied to original device. No ethics. Besides, ChatGPT is free and superior. And it doesn't say it's "tired of talking" about a single topic like this app does.
