I feel like the app is great, I feel like it has a lot to offer but its not free. Of course there's a subscription offer, but I was only able to send around 6 messages to my penpal before it told me to pick a subscription. Should add a completely free version. Also no ads, although I only had it for a few minutes.

Hey Trey, we're so glad to hear you think the app is great & has a lot to offer. As we're a small team of 4, we had to introduce subscriptions as we scaled to cover our costs, hope you understand. The app would be riddled with ads otherwise! Email me at sam@sylvi.ai and I can give you a discount, as we'd love you to continue learning with us

This app has been extremely helpful in helping me get some practice in learning German, as I don't really have many people to practice with. The tutor has been extremely helpful in helping correct some mistakes I have made, and the AI pen pals that you're able to talk with have been very helpful in giving me some experience with German grammar rules. Would recommend.

PLEASE REPLY TO THIS MESSEGE! I was amazed by how the AI responded to my messages and corrected my grammar. Because of this, I’m very eager to subscribe, but whenever I try to click the subscription button, I get an error saying, "There was a problem with the store." Please help me resolve this, as I really want to keep using the app to improve my Spanish speaking skills!

John, thanks so much for flagging this and sorry you've hit a wall trying to subscribe! Really glad to hear the corrections have been landing well thought and you want to keep going with your Spanish. Could you email me at sam@sylvi.ai with a screenshot of the error and we'll get to the bottom of it and make sure you can subscribe. Gracias, Sam 🫶
