Imprescindible para quien quiera optimizar sus resultados. ### 5/5 — Excelente *2025-02-04, version 4.29.3* Fácil de utilizar, intuitiva y pedagógica. Herramienta necesaria para cualquier preparador físico o deportista que quiera optimizar su rendimiento. ### 2/5 — Ok App but terrible support *2025-01-28* The app does not allow weekly and monthly exports even though the options exist. Reported it to the support and their response was: “…The bug is in your phone…” ### 4/5 — Video function not great *2024-01-04, version 4.27.7* Love how easy it is to use but have been using the video feature to send videos to my coach but doesn’t save videos consistently. I haven’t had a time where it’s save each video in my training sessions, I’m lucky if it saves back to back sets. If I try to edit the length of a video in the app, it will immediately delete the video. ### 4/5 — Nueva actualización *2023-06-01, version 4.26.2* Con la ultima actualización ahora no puedo compartir mis repeticiones (el formato tipo excel) porque aparece en blanco sin los números. ### 5/5 — Money well-spent. *2023-02-20, version 4.25.1* The hardware is top-notch, well-made, and functions exactly as described. I was initially concerned that the encoder would feel like a cheap, rushed-to-market throwaway Kickstarter ripoff; these fears were entirely unwarranted. This thing is solid. The mobile app's UX is flawless - intuitive, discoverable, follows the principle-of-least-surprise. I love that I can dump my workouts to CSV with little effort and truly own my data. If you're curious about VBT but feeling a little uncertain as to whether or not the Vitruve delivers on its promises - pull the trigger. You won't regret it. Hats off to the engineering and product teams behind this thing... y'all should be proud of yourselves. ### 2/5 — Not adequate to be a companion app for a 400$ tracker *2022-10-19, version 4.24.1* There's many features that could be added (like graphs on each rep) and it will crash very often while you're training. At this point I'm just using the tracker and use the raw data in my training log. ### 5/5 — Love The Product *2022-09-08, version 4.23.1* Realizable, easy to use, I suggest buying the magnet clip. ## Frequently asked questions about Speed4Lifts ### What does Speed4Lifts do?
