Can’t generate anything as it sends you right back to the sign up screen. ### 1/5 — Don’t waste your money *2024-06-08* I can’t get any images to load. Total waste of money. Haven’t received a response back. ### 2/5 — Mixed Results *2024-04-15* The handful of images that this app created were spectacular- far better than any other AI art generator I’ve used. However, it takes a really long time to generate an image, anywhere from 15 minutes to several hours. I thought paying for the app would speed things up, but I was wrong. ### 1/5 — No free trial; barebones *2024-04-14* There appears to be no free trial; everything I try to do calls up a dialog prompting me to subscribe to the Pro version. Maybe I’m missing something, but I’m not going to subscribe without getting an idea of what the app can do. I’m also wondering whether this is really the official NightCafe app; it seems pretty barebones. ### 2/5 — Frustrating *2024-04-14* The app is good at what it does but after paying £7.99 a week you’re still limited to about 10 generations a day. After that it keeps saying making art work but never loads, you then need to wait 24 hours for it to allow you to generate more very disappointing ### 1/5 — Garbage don’t waste your money *2024-04-11* What your looking for is Nightcafe studio not this, this is just horribly slow and featureless! ### 1/5 — Can’t Get Past 3rd Intro Screen *2024-04-02* I have downloaded and deleted this app several times on my iPad Air and still cannot get past the third introduction screen because the next button is not showing and I cannot move the text up to view the next button to move to whatever is next. On this basis I give this app 1 star because it is unusable to me. ## Most critical reviews (10 lowest-rated) ### 1/5 — Unusable *2025-06-08* I tried twice downloading this and getting it to work. The app locks up and you get stuck. No buttons work and you can’t move forward or backwards ### 1/5 — So SLOW *2025-01-01* The images are beautiful but it takes FOREVER to generate and sometimes never does. ### 1/5 — Can’t use my account *2024-12-31* I have an account on PC but there’s no where to sign in on the app. I’m not paying for it twice so it’s useless. ### 1/5 — Po ups *2024-12-24* I haven’t had the app 2 seconds and 3 things including write a review. So now you get 1 star ### 1/5 — Cant get just one generation free *2024-12-16* Just asks me to pay and i cant even try it ### 1/5 — Welp, never mind. *2024-11-13* I had to cancel a previous subscription a while back and was finally able to re-subscribe today. I’ll be cancelling for good now, since I can’t get it to restore. Too bad. I had fun before. ### 1/5 — Pay or dont bother *2024-11-10, version 4.1.6* USED TO BE FREE! Was one of the first AI generation sites i used (before there was an app!) about 3 yrs ago. Utter garbage now. Cant generate anything at all without paying subscription. Website has deleted old accs. Look elsewhere. Avoid this app; just scamming for $. Plenty of free services better than this garbage. Greedy devs ### 1/5 — Meh *2024-10-25* The app is not as functional as the web based version. You cannot log into your account. It’s fairly lame. ### 1/5 — NightCafe *2024-10-03, version 4.1.6* It is not free and this is not mentioned in its description. ### 1/5 — 🤮 *2024-07-25* WORST APP EVER! Wont let me use the generator without Pro, i understand they need money but youre that desperate?? ## Most praised reviews (10 highest-rated) ### 5/5 — Bom *2025-07-01* Bom ### 5/5 — Great fun! *2024-11-12* Fantastical creations. ### 5/5 — 🤩😍😍🫥 *2024-06-07* We absolutely 🤟 NightCafe, thank you very much! 😁🙃🫠🤪 ### 5/5 — good *2024-04-01* but how to history clear? ### 3/5 — analyzing issues *2024-12-03* Very slow when analyzing some requests. Usually misspells specific words. Has locked up for over an hour when analyzing. No way to cancel or reset unless ios is rebooted. ### 3/5 — Fun while it lasted *2024-11-11* The app was great the first couple of times I used it but it started to freeze up and even after deleting and reinstalling the app, it just kept freezing up. Not paying 7.99 a week for something that doesn’t work. ### 3/5 — Cool app *2024-06-21* I hate credit limitations, but I understand. ### 3/5 — Lacking *2024-04-08* Have used the full PC version for a while and found the app and decided to give it a try. So far I have not seen anything that lets you log into my PC log in and the prompts to create is very limited. Need to add more to the app for functionality, Tenor is a better app but Nightcafe is better creativity and options without the xxx rated adult content that Tenor has. ### 2/5 — Meh *2025-05-24* The unpaid version was pretty good so I went ahead and purchased the pro version… Now I only get one image at a time and it takes a century to generate. ### 2/5 — Ok but *2024-08-09* This was the only app that really understood what I wanted and worked very well but now it only starts thinking, but won’t put any pictures. It was a very good app --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
