Marea turns any map into a precise area and distance calculator. Measure fields, plots, rooftops, lawns and lakes — anything you can see from above — in seconds.
FOUR WAYS TO MEASURE
- Tap to drop pins around a region and get its area instantly.
- Draw a freeform shape with your finger and Marea traces the outline.
- Walk the perimeter and GPS drops pins automatically as you go.
- Auto-detect plots — tap to find buildings, fields and parks already on the map and turn one into a measurement in a single tap.
RESULTS IN EVERY UNIT
Area in square meters, square feet, acres, hectares, square kilometers and square miles — plus the distance between every point.
TRACTOR MODE
Turn your phone into a field-coverage guide. Set your implement width and speed, then drive: Marea records each pass, draws your covered area live, and tracks total distance and worked acreage.…

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

map-area-calculatorWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
