LuckySap is the season log for maple sugarmakers — with a sap-flow forecast built on the rule every sugarmaker knows: freezing nights, thawing days. Check the flow outlook for today and the next two days, log what the buckets brought in, record every boil, and watch the season add up: gallons of sap, gallons of syrup, your best day, and your sap-to-syrup ratio. FREE • Save one sugarbush location and its season tap count; manual place search works without GPS permission • Seasonal Dashboard with recent logs, sap and syrup totals, and regional planning guidance • Faster logging with optional remembered values and measurements from your last entry • September–August seasons keep autumn and spring records together • Free 3-day sap forecast, including today, scored from your local freeze-thaw temperatures • Evening heads-up (optional) when tomorrow looks like a strong run — empty the buckets tonight • A reminder when sugaring season is about to open where you tap, and another on opening day (21 maple states and provinces) • Log every sap collection — date, gallons or liters, sugar reading, taps collected, notes • Track boil sessions & yield — sap boiled, syrup made, hours on the fire, USDA grade, notes • Season stats — totals, first and last collection, best day, average sugar, sap-to-syrup ratio • Records & year-over-year comparison across every season you log • Achievements, from First Tap to Sugarmaker • Sugaring 101 reference guide — when to tap, drilling the tap hole, reading the weather, boiling down, knowing when it's syrup, filtering, and grading • Export collections and boils to CSV • Full backup and restore, including saved photos, costs and preferences • iCloud account status and observed log-transfer activity • English and French (Canada) PREMIUM • Record boil fuel and other costs, plus season expenses; totals stay separate by currency, with recorded cost per unit of syrup and per tap when a season count is available • Extended sap-flow forecast beyond the free 3-day outlook — plan your boil weekends in advance • Syrup yield predictions for every collection, from its gallons and sugar reading, using the updated Rule of 86 (University of Vermont, 2013) • Daily sap chart — every collection day on one chart; tap a bar for that day's detail • Bucket & syrup-color photos on every collection and boil session GOOD TO KNOW • Cost summaries include only what you record, not profit or a complete cost of production. Previously recorded costs stay readable, removable and included in free backups after Premium expires. • The forecast is a planning aid built from the weather forecast, not a promise. Trees don't read forecasts. • Yield predictions are estimates. Your evaporator and your finishing point decide the final number. LuckySap Premium is an auto-renewing yearly subscription.
