Track your stock, map every bag and cage, catch a die-off early, and print tags that pass inspection.
Four screens do almost all the work.
Satellite imagery with each gear unit where it actually sits. Filled dots hold oysters and take the colour of that batch; hollow rings are empty, so free space reads without counting. Tap a plot to add gear. Anything outside your lease is refused, because gear in the wrong parcel prints the wrong harvest area on a tag.
A batch opens with a plain verdict: Normal, Getting worse, or Worse than usual. Then the count behind it, and what to do next. The percentiles and the fitted growth curve sit one tap away under "Show the numbers", for when you want to check the working.
Counts, moves, splits, grading, repairs, harvests. A mortality sample is two big tallies and no keyboard. Everything is appended rather than overwritten, so a correction is a new entry and the original survives. Recording the same thing twice is safe.
One line per batch: where it is, what gear it's in, and a word for how it's doing. Filter to problems, to one lease, or to what's already been harvested. Nobody has to read a number to find the batch that needs them.
