I paid 67 dollars for the singles playbook two months ago and have received nothing. Slick videos and marketing. An app that just wants more money. And a book that I’m sure will never arrive. Do not be fooled by this complete con. ### 1/5 — Good info bad presentation *2024-07-23* I love hearing pros and coaches going in depth but the presenter/host, Will is so annoying. He is always trying to sound smart or like he’s asking really interesting questions but he’s just really awkward and mansplainy. He leads the conversations away from the points that the pros are making. Also the video player built into the app is really crappy so videos glitch out when you turn the phone and are not auto play. ### 1/5 — Trash *2024-03-06* Downloaded 3/4/24 consistently freezes videos delay, must read captions because value on video does not work. ### 1/5 — App won’t display library *2024-02-20* I’m hoping this is just a glitch that will be resolved soon. I just signed up two days ago and everything looked fine initially. Now, I can’t access any content. ### 1/5 — No auto play *2023-12-20* Good information. A but expensive. But it’s very irritating they don’t let you press auto play on the lessons. When asked if we could add this feature they basically tried to make it seem like it was for our benefit that auto play isn’t an option. ### 1/5 — Do not purchase *2022-10-25* This app shows a $0 purchase however you get billed $99 a year for membership that provides nothing. Also you are unable to cancel the membership as it does not log a subscription thru the app/App Store. ### 1/5 — App crashes, but can’t get support *2022-08-26* The app for me crashes, it’s been two weeks now and all I have got is one message saying to reinstall it! Switch it off and on again! Everything has issues, I have no problem with that, I just can’t get any help, I have asked for my money back, no response either! ### 1/5 — No bonus Video shown up *2022-07-30* I purchased the course Crush, but there is no bonus shown up in the app. Where can I see the bonus? I emailed the support but got no reply ### 1/5 — Login and access issues *2022-07-26* Enjoy the content but the user interface is so bad between the website and the app. I’ve been unable to login and customer service has been non responsive. I just have access to old content I’ve previously purchased but nothing from my subscription to FYB University. There are comparable options out there with better user interface and experience ### 2/5 — Hard to say this what I was hoping for… *2023-11-26* I learned about the “New Rules of Singles” from the 2minutetennis Channel which I like a lot about Ryan’s detailed analysis. The overall layout and design of the app is great and easy to navigate through! However, I’m somehow disappointed with the”New rules of singles”. A lot of the key points are mostly based on % between Old vs New rules instead of detailed fundamentals comparisons. I’m sure these % are correct( I assume based on pros) but in my opinion What’s missing are the detailed “why” of those differences.. more importantly, how those % differences apply to Junior or ametur players…that’s exactly the reason I like the 2mintennis. I’m not sure about how other content look like since I only purchased this one. Hopefully there are more fundamentals vs. % comparisons. ## Most praised reviews (6 highest-rated) ### 5/5 — My favorite tennis learning app *2024-05-07* Really simple to use, can access all my tennis courses with a quick tap. Intuitive layout helps me get better at tennis quickly. Thanks, Will and Adam! ### 5/5 — Just getting started *2024-02-26* I just started a one week trial of fuzzy balls, and looked at the section on the windshield wiper forehand. It was very very informative, and went through the progression of biomechanics that made a ton of sense. If I receive another request for a review further down the pike, I will update. So far so good. ### 5/5 — Great value strategy and technical advice *2023-05-22* I love to see coaches and players who know what they are talking about. It is rare and of great value. ### 5/5 — Seems fine *2021-03-12* Log-in and password worked fine for me. App appears to have the entire range of FYB offerings. ### 5/5 — Passwords and login doesn’t work *2021-03-11* Would’ve love to try out the new app. FB sent me the invitation. Unfortunately my old login and password didn’t work nor did the new login and password work. C’est triste! **Developer response:** Hey sorry to hear you're having trouble logging in. Send an email to support@fuzzyyellowballs.com and we'll get you up and running! ### 3/5 — Fine when it works *2024-06-08* The app would not load for me for 5+ days and was not able to access the material I purchased. Good info, working through VolleyRx. Would a expect better smooth working from how much each course costs --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
