Sprayer maths, sorted
Type in the ratio from the product label — 1:500, 0.1% or ppm — and Spray Mix tells you precisely how many ml of concentrate and litres of water to mix. It works the other way round as well: start from the concentrate you have and see how much solution it makes.
Measure your plot on the map
Tap the corners of your garden, allotment, lawn or field on the satellite map and the area appears straight away, or walk the boundary and let GPS trace it for you. Results in m², ares, hectares, acres, sq ft and Japanese tsubo.
Plan the whole job
Choose a saved plot, set your application rate and tank size, and see the total spray volume, total concentrate, how many tank loads you will need and the exact recipe per tank. No more half-empty final tanks or leftover mixed solution.
Powders, granules and spoons
Switch any product between liquid and powder — powder amounts are shown in grams rather than ml. No scales to hand? Spray Mix also shows teaspoons and tablespoons, and you can set how many grams your own teaspoon holds.
Per-area rates straight off the label
For labels such as "5 g per m²" or "20 kg per hectare", the direct-application mode in the Plan tab takes a saved plot and works out the total amount for the whole area.
Offline, private and a one-off purchase
Works completely offline once the map is loaded. No account, no adverts, no subscription — and your data never leaves your phone. Big, glove-friendly controls for iPhone and iPad, designed for use outdoors in all weathers.
Stop doing sprayer maths 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.
