Billiards planning studio

JoEngle

Shot geometry

See angles before you shoot.

Sketch the rack, follow an approximate aiming guide, and keep the diagram for the next practice session.

Three notes from the studio, not a scoreboard.

Ghost-ball aim

Place the cue ball and object balls, choose a pocket, and read an approximate cut angle as the layout moves.

Rail routes

Sketch one-cushion and two-cushion reflections, plus kick and combination sequences, as geometric guides.

Shotbook and drills

Save diagrams, turn a setup into practice, and compare two routes on the same rack.

Effective 19 October 2026. JoEngle does not collect personal data. The app does not ask you to create an account, and it does not send diagrams, practice notes, or device identifiers to a server operated by us.

Shot layouts, drills, practice logs, and comparisons you create are stored locally on your iPhone or iPad. If you export a diagram or training sheet, that file leaves the app only when you choose to share it through the system share sheet.
