Spray Mix: Dilution & Area
Pesticide & fertilizer calc
$1.99 · Designed for iPad. Not verified for macOS.
Measure your plot on the map, get the exact dilution, and know how many tank loads to mix. Offline, one-time purchase, no signup — made for gardeners and growers.
Stop doing sprayer math in your head. Spray Mix turns the three questions every gardener and grower asks — "how big is this plot?", "how much water do I need?", "how much product goes in the tank?" — into three taps.
MEASURE YOUR PLOT ON THE MAP
- Tap the corners of your field, garden or lawn on the satellite map — the area appears instantly
- Or walk the boundary and let GPS trace it for you
- Results in m², ares, hectares, acres, sq ft and Japanese tsubo
- Save your plots and reuse them season after season
GET THE DILUTION RIGHT
- Enter the ratio from the product label (1:500, 0.1%, ppm — all three supported)
- Spray Mix tells you exactly how many ml of concentrate and litres of water to mix
- Works backwards too: start from the concentrate you have and see how much solution it makes
- Save your products with their ratios so next time is one tap
POWDERS, GRANULES AND PER-AREA RATES
- Switch any product between liquid and powder — powder amounts appear in grams, not ml
- No scale in the shed? Spray Mix also shows teaspoons and tablespoons, and you can set how many grams your teaspoon holds
- New direct-application mode for labels like "5 g per m²" or "20 kg per hectare": pick a saved plot and Spray Mix calculates the total for the whole field
- Find it in the Plan tab
PLAN THE WHOLE JOB
- Pick a saved plot, set your application rate and tank size
- See total spray volume, total concentrate, how many tank loads you need, and the exact recipe per tank
- No more half-empty last tanks or leftover mixed solution
MADE FOR REAL WORK
- Works completely offline once the map is loaded — no account, no ads, no subscription
- One-time purchase. Your data never leaves your phone
- Big, glove-friendly controls designed for use in the field
- iPhone and iPad
Whether you are spraying fruit trees, feeding a vegetable garden with liquid fertilizer, treating a lawn, or managing a small farm, Spray Mix removes the guesswork between the product label and the sprayer tank.
Always read and follow the product label. Spray Mix calculates quantities; the label is the law.
