And it's quite difficult in returning the video, like in the short clip, if i want to rewatch the previous one, it's keep going forward while i go back **Developer response:** Hi there! Thank you for using Gravity and sharing your feedback! Our team is working hard to improve subtitle accuracy, and you can expect much better, freshly updated subtitles very soon! We're also aware of the issue with going back to previous clips, and a fix is coming in an upcoming update. Thank you for your patience! :) ### 4/5 — good, but.. *2026-09-07* I was intrigued when I saw, but know this app isn't free! Had to delete because I'm saving up. **Developer response:** Hi Madison, thanks for giving Gravity a try! We completely understand, and we don’t want cost to stop you from learning with us. Please reach out to us at support@learngravity.com, we’d be happy to see how we can help. We’d love to have you back! ### 5/5 — PEAK *2026-08-08* Not only is a lot of the content extremely entertaining but it is also very useful for learning Japanese. A lot of the videos that are dedicated to teaching on there are very informative and easy to understand. I love the way that they have the subtitles because it is large and easy to read in my phone and it shows the individual meaning of each word not just the big idea, that helps with understanding sentence structure. It can be a little glitchy sometimes and it did rage bait me once but I quickly realized that pausing it and playing it fixed whatever problem I was having. Overall really good but ngl they should make it free🌝 ### 5/5 — Useful learning app! *2026-07-26* Interesting app, I like that I can watch any type of Japanese content and choose which words I want to learn. There's also a doomscrolling feature which is a little buggy at times but is nice to watch short clips during my morning commute while still learning Japanese ### 5/5 — Great language learning app *2026-07-24* This app is helpful and I’ve been using it daily to learn Japanese. ### 5/5 — Fun and Awesome *2026-07-23* Being a new Japanese learner this has been a great way to learn and has good immersion which helps keep the memory and comprehension high! ### 5/5 — Feeling the gravity 🌏💫 *2026-06-27* Really loving the app so far! It makes reviewing flashcards fun while offering a more focused learning experience than duolingo. Also like that you can take photos to capture aspects of your own life, making it feel like a personalized dictionary and language diary. ## Most critical reviews (10 lowest-rated) ### 1/5 — Request *2026-10-12* Give me money back, I didn’t even use the this app. **Developer response:** Hi there, we're really sorry about the unexpected charge. We understand how frustrating this must be. Unfortunately, all App Store refunds are handled directly by Apple. You can submit a refund request at https://reportaproblem.apple.com, and they should be able to help resolve this for you! ### 1/5 — Charges After Cancellation *2026-09-09* DO NOT do the free trial. Even if you cancel several days in advance, they will STILL charge your account the full subscription price after the “free” trial. **Developer response:** Hi there, we take issues like this very seriously. All iOS billing and cancellations are handled directly by Apple, but we'd still like to investigate what happened in your case. Please reach out to us at support@learngravity.com so we can look into this with you. ### 1/5 — Does not work *2026-09-09* Still has the blast off infinite loop. Really is a shame because the app looks fun :/ **Developer response:** We’re extremely sorry about this! We thought we had fixed the Blast-off issue already, but it looks like a recent change may have brought it back. Our team is really sorry, and we’ll get this fixed again as soon as possible. In the meantime, could you reach out to us at support@learngravity.com. We’d really like to make up for this frustrating experience :( ### 1/5 — Can't use the app *2026-09-06* Crashed three times in a row **Developer response:** Hi, we looked into this further and found that the crashes can happen when your device is very low on available storage. Freeing up some space should resolve the issue. We’re also working on making this much clearer in the app instead of letting it result in a crash. Sorry again for the frustrating experience! ### 1/5 — Blast off bug *2026-09-01* Just downloaded and all i see is “blast off”. **Developer response:** Hi Eve, we’re very sorry you had this experience. A fix is now available in version 2.4.0, please update Gravity and try again. Also, please email us at support@learngravity.com; we’d really like to make up for the bad experience! ### 1/5 — Frozen *2026-08-28* Downloaded today. App shows “Blast Off” and never changes screen. Regardless of taps or shakes and no other prompts to do anything different. **Developer response:** Hi there, a fix is now available in the latest version, 2.4.0. Please update Gravity and try again. As an apology for the bad experience, please email us at support@learngravity.com, we’d really like to make this right. ### 2/5 — Videos *2026-10-19* Currently only a few videos work for me. I consistently get video unavailable message. App seems cool though if it works consistently **Developer response:** Hi there! We're sorry to hear you're having trouble accessing videos! Video availability can sometimes be affected by VPNs, ad blockers, or regional restrictions. Could you please reach out to us at support@learngravity.com? We'd love to investigate what's happening and help get things working for you! :) ### 2/5 — Like always *2026-10-19* Genuinely liked the app at first because it was able to watch a video. But like always turns out the app isn’t free. I get trying to make money but really? I have to pay for everything? You might as well make my pay to even download the app it’s literally unnecessary.The only thing free is the dictionary and the dictionary saved me from giving it a one star because the dictionary is actually good but literally can’t do anything else. **Developer response:** Hi there! We're sorry to hear about your frustration. While subscriptions help us keep Gravity running and improving, we never want pricing to stand in the way of learning. We're always exploring ways to make Gravity more accessible and would love to hear your thoughts! Please reach out to support@learngravity.com so we can make things right :) ### 3/5 — Good but not great *2026-09-29* The apps okay. My main issue is that the subtitles are usually not accurate. Of course it’s auto generated so I don’t expect it to be 100% but about 40% of sentences have some kind of error in them. Also something else I’m finding really annoying is the little boxes the subtitles appear in while watching a video are grouped with too few words in them and they slide to the next box too quickly, so it has hard to read the subtitles when the boxes are constantly moving. It would be better if the whole sentences was in one box and not just a few words. Overall a good tool, but needs improvement **Developer response:** Hi there, thank you for the detailed feedback! We’re aware of both of these issues and have actually been working on them. A major update is coming very soon with fresh, more thoroughly validated transcripts for better subtitle accuracy, as well as improved sentence and word grouping so the subtitle boxes are easier to follow and don’t move as quickly. We really appreciate your feedback and patience while we get these improvements ready! ❤️ ### 4/5 — Bonne appli avec une marge de progression *2026-10-21* Bonne application d’apprentissage du japonais à travers des vidéos trouvées sur les réseaux, et sur des thèmes qui nous intéressent. Il est plutôt simple d’apprendre des mots placés directement dans leur contexte ainsi que de demander davantage d’explications à l’IA intégrée. De plus le prix reste abordable (50€/an) même pour un étudiant. Cependant, certaines erreurs d’audio peuvent fausser légèrement l’expérience. Il serait bien aussi de pouvoir ajouter aux mots à apprendre les mots recherchés dans le dictionnaire présent dans l’appli. ## Most praised reviews (10 highest-rated) ### 5/5 — Great for Chinese *2026-10-23* I am learning mandarin and this is such a great way to get consistent practice ### 5/5 — One day in and it’s amazing *2026-10-20* I think immediately after downloading i realized it’s the best Japanese learning app on the market right now. Only complaints are that I want more content! 😫 May I suggest ヒカキン or ポッキー? I loved the one horror stream that was featured on the app but would love to see more stream content. Flashcard system is great and user friendly, only issue is sometimes the pronunciation is off but as long as you have the pitch accent and the reading on the back of the flashcard it’s pretty easy to figure out. Love it so far! **Developer response:** Thank you so much for the amazing review! ❤️ Our very next update will bring a fresh wave of videos and improved transcripts, and we'll make sure to add the creators you suggested! We also just released a brand-new voice system today that should address the pronunciation issues you mentioned. Thank you for supporting Gravity! ### 5/5 — Great app *2026-10-10* Please add dakuon, handakuon and yōon to the kana learning section. For the live translation in videos: please add an option so that when a sentence ends, it doesn't jump straight to the next one, but lets you repeat it instead. Sometimes it's still too fast for me, even at 0.5x speed. This app has a lot of potential thank you I am looking forward to subscribe! **Developer response:** Hi there! Thank you so much for your kind words and suggestions! We're planning to add these improvements based on your feedback in an upcoming update, including more kana practice and the option to repeat sentences. Thanks for helping us make Gravity better! :) ### 5/5 — Keen to see where it goes! *2026-10-06* I’ve just finished the free trial and am thinking of continuing on. The app has been a good way to expose myself to new content I wouldn’t normally come across when just YouTubing “N5 Japanese listening”. The app is clean and visually nice to use. Some features I hope to see in the future would be: - improved captions so that words are captured in their context, sometimes verbs or words are split into two when in forms like て so creating flashcards - an option when watching a video to go card by card and tap to play, so it’s easier to repeat a card over when shadowing and working on pronunciation - when searching words in the dictionary to be able to add to my flashcards collection Keen to see where this app goes, recommend trying it out! **Developer response:** Thank you so much for the thoughtful feedback and support! ❤️ We're really glad you're enjoying Gravity! Adding words directly from the dictionary to flashcards is coming very soon, and we're working on improving the shadowing experience. We'll also add your transcript suggestions to our to-do list, as we're constantly working to make them better. Thanks for helping us improve Gravity! ### 5/5 — Great App! *2026-10-04* I wish there was a way to adjust audio levels. The spoken words on flash cards can be much softer than the sound effects. Also, sometimes removing a card from a deck does not work. **Developer response:** Thank you for the feedback! We’ll continue iterating on the flashcard experience, and you can expect the audio balance and card removal issues to be addressed in the next update. We really appreciate you helping us make Gravity better! :) ### 5/5 — Money *2026-10-04* Best app if it will be free **Developer response:** Thank you for the feedback! We understand your concern about the price and are always looking at ways to make Gravity more accessible while continuing to improve the experience. We really appreciate your support :) ### 5/5 — Tried a billion Japanese learning apps- this is THE ONE *2026-09-15* Unlike other language learning apps I’ve seen that run a similar subbed video format with translations, this one actually tokenizes each word with a separate translation, which is super helpful for learning Japanese, since word-for-word translations can differ vastly from words in the context of a sentence. Nouns, adjectives, etc. are also color-coded. If I STILL don’t get something, there’s an additional feature that explains each word in its given context. There’s also practically no friction when I want to save terms to create flashcards. And BRO- the flashcards are easily the best I’ve seen (I’ve had Quizlet Plus for almost a decade). It not only provides audio pronunciation but visualizations for the pitch accents as well. Great to see that they’re pushing out updates so frequently and announcing all the changes. W APP! **Developer response:** Thanks a ton for the kind words! It really means a lot to us and keeps us motivated to keep improving the app and making it the best learning experience we can. If you ever have any feedback or feature requests, feel free to reach out to us at support@learngravity.com — we’d love to hear from you! ### 5/5 — very impressive app! *2026-09-13* i’ve been using the app for a couple weeks now and i’m finding it super helpful training me for my upcoming trip to japan! better learning system than other apps because this one’s more custom to how i want to learn. **Developer response:** Thanks for the review! We hope that you have a great time in Japan! ### 5/5 — Eine herausragende App um Japanisch zu lernen *2026-09-10* Ich habe schon einige verschiedene Apps zum Sprachenlernen ausprobiert, aber Gravity hat mich wirklich überzeugt. Gravity schafft es, Japanisch auf eine sehr strukturierte, verständliche und gleichzeitig motivierende Art und Weise zu vermitteln. Besonders begeistert bin ich davon, dass man nicht einfach nur einzelne Vokabeln auswendig lernt, sondern ein echtes Gefühl für die japanische Sprache entwickelt. Vokabeln, Grammatik und Wortschatz werden hier sinnvoll und strukturiert miteinander verbunden, sodass man Schritt für Schritt Fortschritte macht, ohne sich überfordert zu fühlen. Durch den Aufbau fällt es viel leichter, regelmäßig zu lernen und dranzubleiben, da sich Gravity exzellent in den Alltag integrieren lässt. Auch die Möglichkeit, bereits Gelerntes immer wieder zu wiederholen, finde ich besonders hilfreich. Was mir außerdem sehr gut gefällt, ist die übersichtliche und intuitive Bedienung. Das Design von Gravity wirkt modern, gut durchdacht und nicht unnötig kompliziert. Ich habe das Gefühl, dass mich Gravity wirklich meinem Ziel näherbringt, Japanisch nicht nur zu lernen, sondern die Sprache tatsächlich zu verstehen und anzuwenden. Mein Fazit: Klare 5 Sterne und absolute Empfehlung! ### 5/5 — Helpful *2026-08-10* Very applicable way to learn a new language. I’ve attempted multiple times through different means and find it a struggle to make the time but this app has allowed me to learn while doing the things I already do every day and I’m finding it very helpful. 10000 stars. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
