I have more than half of my videos still being analyzed! I want my money back!!! ### 1/5 — Doesn’t work *2024-12-06, version 3.3.7* I subscribed for one month, 0 analysis so far after 10 recorded videos. Waste of time and money. ### 1/5 — Absolute junk *2024-10-31, version 3.3.7* Just tried on my new iPhone, simply does not work. Lets you record only from one camera, after processing, the ai evaluator gives error and deletes the video… Contacted support by email and it came back of undeliverable… I think it is fake ### 1/5 — Low quality *2024-06-28, version 3.3.6* Doesn’t recognise swing but provides 81 mark. Very poor quality. ### 1/5 — Does not work at all *2024-06-03, version 3.3.6* Videos uploaded stuck for a few days at “analyzing” phase ### 1/5 — Não carrega o vídeo, só fica em análise. *2023-09-13* Horrível!!!! Horrível ! Horrível! Deveriam devolver o dinheiro. O vídeo fica em análise , já tive vídeo apagado. Enfim não funciona. Achei que seria a solução para análise biomecânica dos meus atletas. Mas realmente não foi. Péssima experiência. **Developer response:** Hi and sorry for your experience. There might be something wrong with the setup, or a poor internet connection. Please contact support@sevensix.no for assistance ### 1/5 — Highly Dysfunctional *2023-09-02, version 3.3.6* It’s a great concept, but highly dysfunctional. Screen goes off during recording, so you have to turn off auto-lock before starting. If you’re using a tripod, you hit a few strokes thinking you’ve got enough source material for analysis, only to find out that it just captured you walking back to the camera. It is a good concept, but to buggy. ### 2/5 — Cool but glitchy *2025-04-20, version 3.3.7* When it works it seems cool and possibly helpful but it would be nice if we could use the front camera. Also the camera may work at first use then if I try to record another trial the camera isn’t working. I have to exit out and restart the trial for the camera to maybe work. ### 2/5 — Analyzing freeze *2023-11-04, version 3.3.6* The app has bug and cannot finish analyzing videos. Pls fix! ### 3/5 — Cool idea doesn’t work that well *2024-03-25, version 3.3.6* It’s ok ## Most praised reviews (7 highest-rated) ### 5/5 — amazing *2024-05-02, version 3.3.6* amazing ### 5/5 — Analisando vídeo eternamente *2023-07-25* Fiz assinatura e no 5º vídeo ele ficou analisando eternamente e não termina de carregar…. Frustrado **Developer response:** Sorry for your experience. A bad internet connection might be the reason. Please reach out to support@sevensix.no for assistance ### 5/5 — Avis *2022-10-30* Trop bien et nécessaire **Developer response:** Merci pour vos commentaires, très apprécié ### 5/5 — The future of tennis training is here. *2022-09-22, version 3.0.4* What a truly impressive app! Thanks to SevenSix’s cutting edge technology (probably the best in the market), I was able to fix and improve my tennis technique. Make no mistake - even if you have a tennis coach - this app is a valuable tool to enhance your performance. There are some things even the human eye can’t catch, after all! I look forward to continue my improvement, and can’t wait for new updates. ### 5/5 — Amazing app to improve your tennis technique! *2022-07-27* I was so impressed on the speed of the analysis and visualisation compared to the Pro swing. The app has really helped me focus on what I need to work on with my technique. Quick and easy to use and packed with lots of fantastic features and tech. I’d recommend this to any tennis player! **Developer response:** Thank you for your support! ### 5/5 — Great app! *2022-02-22* Very well made! ### 3/5 — Vidéo analysing *2022-09-27* Hello, how much Time to get a video analysing done ? I saw instantly but i’ve been waiting like 10 min **Developer response:** It takes down to 3 seconds with an Iphone X or newer. It seems your internet connection was too poor during the video capture. Please try again, if you still experience problems please contact support@sevensix.no --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
