just checked it out, while i don't really need this app anymore its actually really damn good!
7 pounds a month or 50 pounds a year is a lot to pay for subtitles on someone else's videos. They are free on YouTube.

Hi there! We understand your concerns about pricing. Gravity's goal is to help you make the most out of real content with interactive transcripts, vocabulary explanations, memory-tracked flashcards, and more. We never want pricing to stand in the way of learning, so we'd be happy to offer you a free month! Contact us at support@learngravity.com :)
love the idea of the app but think it lacks some directionality to really help those improve. right idea but not solidified. things id love to see: .75x speed, often .5 feels too slow and 1x is too fast. would also love a real guide in how to maximize your learning with the app, showing us how to take the passive style of learning and really apply it further then saving words. feels like your given the keys but not the instructions to be successful.

Thanks for the thoughtful feedback! We're adding more playback speed options, including 0.75x, in our next update coming within the week. The update after that will introduce a simple tutorial explaining the core study loop and how to get the most out of Gravity. We really appreciate your suggestions!
I would only use this for learning new words. learn the grammar and basics elsewhere because it is not always 100% accurate. especially when a sentence continues onto another section separately. it seems to guess the first part and then tag the second part on incorrectly. but it is still amazing for learning new words and how different media forms use them.

Hi JM, thanks for the thoughtful review! We're aware of some inaccuracies in our transcriptions, and are actively working to improve them. We're still early in development and are committed to making Gravity more accurate and accessible, including better support for beginners. We appreciate your feedback!
Concept is cool, but the translations when watching videos are inaccurate and don't make sense most of the time. This is similar to if you google lens japanese text and get nonsense
Developer reply
Hi there, we’re sorry that some translations haven’t met your expectations. We’re aware there’s room for improvement and the team has been working hard on making translations more accurate and natural. You can expect significant improvements in our upcoming update! Thank you for your feedback and patience as we continue improving Gravity! :)
would give it 0 it doesn't let you do anything without paying not including the "trial period" which I don't count because it just means you'll have to pay when it's over. at that point you might as well make it a paid app.

Hi there, we're sorry for the frustration with Gravity's pricing. While subscriptions help us support our team and improve the app, we never want cost to be a barrier to learning. We'd be happy to offer you a free month so you can learn with Gravity without any pressure. Please reach out to us at support@learngravity.com! :)
A great app for learning practical, everyday Japanese vocabulary. My only issue is that words you struggle with don't come back for review. An Anki-style spaced repetition system that focuses on words you haven't mastered would make this a 5-star app!
Developer reply
Thanks so much for the kind review, Runa! We're currently overhauling our spaced repetition system so tricky words continue to return until you've truly mastered them. Stay tuned for the update, and we hope it earns that fifth star! :)
paid app - cool concept, first day I managed to do a section, tried again a couple days later and am forced to subscribe
Developer reply
Sorry for the frustration, Pragash! Your first 24 hours are free with no payment details, and after that a plan is needed to keep going. To make up for it, we'd love to give you a free month: email support@learngravity.com and we'll send you an access code to redeem in Settings > Enter access code. Thanks for giving Gravity a try!

Too many mistakes in subtitles to comsider as a serious tool, and for CAD$60 a year? add a lifetime and reduce price by alot and i would think about it. if it was $30 for lifetime i would, its just another ai language learning tool
Developer reply
