Vector Poise

À propos de l'application

Make each target and result part of your next practice session. Vector Poise is an offline notebook for badminton, tennis and flying disc players practising placement independently.

A total hit count can hide zones you rarely test. Record where you intended to place each shot or throw, then mark where it actually landed. Review your coverage, hit rate and directions of misses before preparing the next 12 targets.

SET UP YOUR PRACTICE
Create a layout with 2–9 target zones on a 5×5 grid. Record the physical boundaries, viewing side, distance and conditions so you can return to the same setup. Six editable examples offer starting layouts across the three sports.

RECORD 12 ATTEMPTS
Preview the target sequence before you begin. After each attempt, tap the actual result cell or choose outside the grid. Undo the latest entry and correct results while the session is still a draft. Review all 12 entries before completing the session.

SEE WHAT YOUR RESULTS SHOW
Check observation counts for each zone, exact-cell hit rates, results outside the grid and median offsets for results within it. Fractions and observation counts sit alongside percentages to show how much practice each figure represents. Review one completed session or the latest 120 attempts for that layout version.

PREPARE YOUR NEXT TARGETS
Generate a sequence that balances attempt counts across all target zones, or focus on a selected set of at least two zones. See why each target was chosen, including existing coverage and miss rates. Save a rule that recalculates from your history, or save a fixed sequence of 12 targets to repeat exactly.

KEEP COMPARISONS CONSISTENT
Changes to your zones, distance or conditions create a separate layout version. History stays with its original version. Repeat a previous target sequence or compare two completed sessions from the same version, with equal weighting across zones tested in both and excluded zones shown separately.

WORK OFFLINE
All practice records stay locally on your device. No account or internet connection is required, and there are no adverts or payments.

Vector Poise relies on manual entries and consistent physical markings. Grid results describe approximate placement, rather than distances in centimetres. Comparisons summarise your recorded results and do not establish proven improvement. Completed sessions cannot be edited; an incorrect session can be deleted and repeated. Uninstalling the app removes its local history.
