Film one delivery. See your action the way a coach does.

On iPhone: open Camera, swipe to Slo-Mo, and record. On Android: look for Slow motion or Super Slow-mo in your camera modes. Higher frame rates improve fast-motion and timing coverage.

Start with the phone steady at hip height, side-on to the crease from your bowling-arm side, far enough back to keep your full body and delivery in frame. Record one delivery. If other phones filmed that same delivery from front- or back-on, add those clips too and label each view. Our step-by-step filming guide covers camera height, distance and the mistakes that cost you measurements.

No. One side-on clip is the classic starting point, and it supports the largest group of measurements: front-leg brace, back knee, trunk tilt, elbow opening, arm speed, delivery stride and foot strike.

Extra front- or back-on phones on the same delivery add the measurements a side camera physically cannot see, such as sideways trunk tilt and whether your run-up steps cross your own line. The sample analysis on this page came from three phones at once: the side-on clip returned 13 of its 15 measurements, and the two extra cameras added the rest. What extra cameras never do is get blended into pretend 3D. Every number names the single view it came from.

It is where the training happens. The 4-week plan from your analysis arrives as ready-made routines, and you can build your own for the gym and the nets. Start one and tick it off set by set: weight and reps, holds, distances, or balls and overs in a bowling spell.

FastBowlingLab keeps your personal bests, shows your weekly bowling workload against your usual week, and suggests the next step, such as the next session in your plan, a lighter day after a big jump in load, or filming your action again when the four weeks are up.

Keep training. A session in progress is kept on your phone and saved to your account whenever there is a connection, so a bad signal never loses a set. A session you finish offline is uploaded as soon as you are back online.

Your clips upload over an encrypted connection to private storage that only your account can access. They're processed to generate your analysis and kept so you can rewatch and compare re-tests. You can delete any video (or your whole account) at any time, and deletion removes the footage from storage.

No, and you should be suspicious of any phone app that claims it can. The ICC's 15° rule is about elbow extension, which official assessments measure with marker-based 3D motion capture in a biomechanics lab. Ordinary phone clips cannot measure elbow extension to that standard, so FastBowlingLab never issues legality verdicts. We show a visible elbow-opening cue from the side-on view, clearly labelled as a technique observation, and explain when a value is unavailable.

The native apps are available on the App Store and Google Play, so you can film, upload and read your analysis on the phone that shot it, with a push notification the moment it's ready, and log your training there too. The web app does the same things in your phone's browser: same account, same analyses, nothing to migrate later.

Yes. Every analysis exports to a PDF designed for exactly that: your results, their sources, the explanations, annotated stills and the 4-week plan, in a format you can WhatsApp or email to a coach.

If the footage does not show a usable bowling delivery, for example it is too dark or the bowler cannot be tracked, the analysis unit you spent is returned. A usable clip from one view can still produce results, with view-specific rows explaining what was unavailable. Plans can be cancelled anytime: you keep access until the end of the period you've paid for.

Yes. FastBowlingLab lists fast-bowling coaches whose profiles our team has reviewed. You can message one, share an analysis so they see exactly what you see, and agree a time for a live one-to-one session in the chat. You pay the coach directly, at the price on their profile.
