However, that option is nowhere to be found in app. Is the developer hoping to catch a fish? The app seems to be good, though. ### 4/5 — Seems to work OK, however... *2025-03-10* Please make in LANDSCAPE mode for iPad Pro with attached keyboard use! I refuse to type sideways! Note: Developer states landscape may be coming in future updates--4 stars. **Developer response:** Perhaps we will make your wish in the next versions. ### 2/5 — Seems to work OK, however... *2025-03-02* Please make in LANDSCAPE mode for iPad Pro with attached keyboard use! I refuse to type sideways! **Developer response:** Perhaps we will make your wish in the next versions. ### 2/5 — Offre mensongère *2025-02-09* Il est noté sur l'appstore Lifetime 0 euros que l'application est gratuite pendant une courte période mais l'option lifetime n'est pas disponible pour y adhérer. Je ne recommande pas. **Developer response:** You must realize that you are too late for this temporary offer. It was still in effect in 2024. ### 4/5 — Excelente *2024-12-06* Es rápida y precisa **Developer response:** Thank you so much! ### 4/5 — No voice responses *2024-12-06* Good app but it’s missing the key ingredient, a voice! **Developer response:** We will listen to your feedback and implement such a feature. ### 5/5 — 100% *2024-12-05* The Best, no fast!!! **Developer response:** Thank you! ### 5/5 — My assistant *2024-12-05* Very good and simplified GUI make it easy to use without going to search for where to type quickly to get answer which is always on point. **Developer response:** We are sincerely very happy that you like our app! ### 5/5 — Pas mal du tout ! *2024-12-05* Je n’en suis qu’aux premiers tests, mais les résultats obtenus sont très bon ! La traduction de texte est quasi du même niveau que Deepl et l’app dont l’interface n’est pas encore en français, répond par contre très bien sur des commandes écrites et vocales en français. **Developer response:** Nous sommes sincèrement très heureux que vous aimiez notre application ! ### 1/5 — Be Careful! GPT 3.5 *2024-12-05* screenshots state that GPT version is 4-o, but actually the version is 3.5! **Developer response:** We are using the exact version shown in the screenshots. Your feedback is not useful for other users, but thanks anyway! ## Most critical reviews (10 lowest-rated) ### 1/5 — Stopped working *2025-04-06* This was a useful app but it stopped working after a while **Developer response:** We apologize! There were temporary maintenance works, they have been fixed and the application is working again. ### 1/5 — It stopped responding *2025-04-03, version 1.2.1* Please fix. It no longer works. ### 1/5 — In-App purchase doesn’t match *2025-01-02, version 1.2.1* Unfortunately no lifetime version available. ### 1/5 — AppAdvice lifetime promo (Bait & Switch) *2024-12-11* 12/10/24 after seeing the developers response were obviously having language issues or something is definitely off AS we definitely downloaded the app in the time period the app was supposed to be free Or maybe we misunderstood TODAY only meant 1 hour during the day??? Nonetheless we stand by everything we wrote it was downloaded on the date the promotion was available and we screenshot that no free plan was showing up as an option. We also actually read your privacy policy and terms of use So for you to say you don’t collect ANY data nor share ANY is absolutely false according to your own privacy policies. However the app has no lifetime subscription for free as stated in the AppAdvice promotion only paid options and even the paid options are not lifetime subscription. Sad 🤮🙈🥲 On the positive or less sketchy the app is actually probably helpful for students or anyone studying JUST frustrating the app developers are liars which has to cause concerns about your privacy and the data mining they collect and sell off to 3rd parties. **Developer response:** Sorry you gave us a low rating. You did not have time to use a temporary offer that has already expired. We do not collect or share data with third parties. ### 1/5 — Cannot see lifetime *2024-12-08* I saw lifetime is 0 but cannot registration **Developer response:** Sorry you gave us a low rating. You did not have time to use a temporary offer that has already expired. ### 1/5 — AppAdvice lifetime promo (Bait & Switch) *2024-12-07* However the app has no lifetime subscription for free as stated in the AppAdvice promotion only paid options and even the paid options are not lifetime subscription. Sad 🤮🙈🥲 On the positive or less sketchy the app is actually probably helpful for students or anyone studying JUST frustrating the app developers are liars which has to cause concerns about your privacy and the data mining they collect and sell off to 3rd parties. **Developer response:** Sorry you gave us a low rating. You did not have time to use a temporary offer that has already expired. We do not collect or share data with third parties. ### 1/5 — 欺骗 *2024-12-07* 利用限时免费，欺骗用户下载，根本就没有限时免费 **Developer response:** We are very sorry that you did not have time to take advantage of the promotion, which lasted exactly one day. ### 1/5 — Doesn’t work *2024-12-06* I asked this program several times, tried to convince him that it works on 4o, but it insists on version 3.5 Your program claims to use ChatGPT-4o, but when I gave it a task to rewrite an article, it surprisingly said it couldn't complete it, which is consistent with ChatGPT-3's performance. At the same time, I gave this task to another program that also claims to use ChatGPT-4o, and that other program perfectly completed the rewriting task. So, I have reason to believe that your program is not using ChatGPT-4o, but possibly ChatGPT-3 **Developer response:** You are wrong, we use the 4o version exclusively. We cannot use the 3.5 version, as it costs much more. ### 1/5 — No la actualizan *2024-12-06* Lleva más de un año sin ser actualizada su base de datos. **Developer response:** Lamentamos que la aplicación no haya sido de tu agrado. ### 1/5 — Português BR *2024-12-05* Não tem o idioma Português do Brasil **Developer response:** We will implement it in the future. ## Most praised reviews (10 highest-rated) ### 5/5 — Perfect app *2024-12-07* I was skeptical about using an AI assistant, but Lumi has exceeded my expectations. Whether I need help with translations, cooking, or learning new skills, Lumi is always there to provide support. **Developer response:** Thank you so much for your feedback! ### 5/5 — I’m TOTALLY impressed *2024-12-06* I’m not a big on writing review ms. But today I’m making an exception, bc I am beyond impressed with this app! It’s like having a creative genius in my pocket. Today alone, it’s tackled everything I threw at it, no matter how off-the-wall my requests were. It helped me write 2 letters, edited a paper with ease, and even wrote a song lyrics that nearly blew me away! The versatility and speed of this app are unmatched. Whether you need to be productive, creative, or just plain adventurous, this app delivers every single time. Highly recommend for anyone who loves exploring possibilities! I know I’m sure glad I decided to give it a whirl. Two thumbs up! 👍🏻👍🏻 **Developer response:** Wow, it's so nice to read reviews like this, thank you so much! ### 5/5 — It’s good now *2024-12-06, version 1.2.1* I was unable to step beyond the paywall in spite of your offer.
