Build your range session.
Tell it how many balls you bought, what is actually in your bag, and what you are trying to fix. It builds the plan around that, walks you through it, and tells you what it noticed at the end.
Three questions, then a plan. Takes about thirty seconds to set up.
Logging your misses is optional and the session works fine without it. If you do log, the summary at the end tells you what your pattern was, and that pattern is the single most useful thing you can hand a coach.
Nothing leaves your phone. It saves in your browser. You can export a session to a file and load it back later.
Three questions
Whatever the bucket actually holds. Guess if you have to, the plan scales either way. Small is usually better than large.
Only tick what you actually have with you. Every block gets built around a club you own. If you skip something, the plan substitutes rather than telling you to use a club you do not have.
Optional, and pick at most two or three. Each one you add takes balls away from everything else, so choosing all of them is the same as choosing none. Leave it blank for a balanced session.
Entirely optional. If it is on, you get a tap-row of buttons on each block and a read on your patterns at the end. If it is off, the session just runs.
