absolutely sick of apps these days that make you think it's free by filling out a very long questionnaire and info about yourself and what you need help with spending about 20 to 30 minutes filling it out to the very last step being how much can you afford to pay now I am really sick of this trick and that's why I'm rating it one star. please forward with your intentions app and you may move forward in this world as an app

Absolutely appreciate your feedback. Our goal with the questions is to personalize your experience — not to trick you. We’re just as careful when curating content to keep it high-quality and relevant. Still, we’re working to make onboarding faster and clearer. Thanks for helping us improve!

The app is great, but I'm missing a few features: - some way of selecting the current level of English(e.g, via some test during the onboarding or just a selector in the settings). This feature will allow users to interact with vocabulary more smoothly - An ability to create your own list of cards to be able to learn and/or repeat them intensively. Maybe some sharing functionality to allow English tutors to prepare and share these lists with their students

$69.99 WHAT!!!😲😲😲 A 3 day free trial with stipulations is NOT FREE, PAY $69.99 and use 3 days free🤨🧐🤔. Whether it's a 3 day, 5 day, or 7 day free trial, it should be WITHOUT a stipulation. "YOU CAN'T CATCH A FISH WITH NO BAIT." REAL free trials draw people. Thanks for the extremely high price. I found something better on YouTube. FREE, ITS AN HOUR, NEW WORDS, PRONUNCIATION, DEFINITION, AND USED IN A SENTENCE. 💞 Thanks for responding. Like yours also, BUT WAY TOO MUCH 💰💰💰
