What you can do in Spraybook on the web
Per-tree spray logbook
Product from your shelf, the trees or the whole block you covered, date, growth stage, tank size, amount mixed and a weather note — grouped by month and searchable by tree, product, ingredient or stage.
REI and PHI countdowns
Every logged spray produces two live progress rings straight from the label numbers: when it is safe to work under those trees again, and when the fruit is safe to pick.
Backpack mix calculator
Converts a label rate given per gallon, per 100 gallons or per acre into exact ounces, tablespoons, teaspoons, grams or millilitres for your actual tank — with saved sprayer profiles and a friendly second unit.
Orchard and blocks
Your trees organised into blocks (Front Yard, Back Slope, Berry Row), each with crop, variety, year planted, live countdowns and full spray history.
Product shelf
Type a product once — name, active ingredient, REI hours, PHI days, default label rate and basis — and every future log entry, countdown and mix reuses it.
Season schedule for six crops
The full bundled growth-stage timeline for apple, peach, pear, cherry, grape and berry — dormant, green tip, pink, petal fall, cover sprays, pre-harvest — with what to watch for at each stage. Timing guidance only, never product recommendations.
Season record export
The whole logbook as a CSV spray record for a market stand or your own memory, plus a full JSON backup.

Questions
Is the web version of Spraybook free?+
Yes. Every screen is free to use: no subscription, no in-app purchases, no account.
Do I need an account?+
No. Open Spraybook and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a Spraybook app for iPhone or Android?+
Not yet. Spraybook is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
