Management
Hive Tracker
Manage apiaries, record inspections, and monitor hive health with a simple decision-first system. Free to use.
Swarm Log
Log captured swarms with date, weather, method, size, and photos. Track comb-drawn progress and link to the hive it becomes.
Forage Range Map
Drop a pin on your apiary and see the 1, 2 and 3 mile forage rings your bees actually work, with the acreage each circle covers.
Bee Forage & Nectar Flow Calendar
See what blooms for your bees through the season by region, when the major nectar flows land and where the summer dearth falls.
Hive Inspection Checklist
Record queen status, stores, space, and pests during inspections. Get smart suggestions for next steps.
Feeding
Sugar Syrup Calculator
Calculate exact sugar and water amounts for 1:1 or 2:1 bee syrup. Supports metric and imperial, weight or volume.
Pollen Patty Calculator
Scale Kamon Reynolds's Ultra Bee pollen patty recipe to any batch size. Sugar + water + oil or Pro Sweet base.
Overwinter Feed Calculator
Estimate how much honey or syrup your hives need for winter based on climate zone and current stores.
Queen Timing
Walk-Away Split Timeline
Enter your split date and see exactly when to expect queen cells, emergence, mating flights, and first eggs.
Post-Swarm Timeline
Track new queen development after your hive swarms. Know when to check for eggs and when to worry.
Queen Cell Timeline
Plan around purchased queen cells or known emergence dates. Track milestones from cell to laying queen.
Grafting Timeline
Schedule queen grafting batches with cell capping dates, transfer windows, and expected mating flights.
Queen Marking Color by Year
Look up the international queen marking color for any year. Includes mnemonic and queen age calculator.
Harvest
Honey Yield Calculator
Convert harvest weight to jar counts and estimate revenue. Plan your bottle inventory and pricing.
Honey Moisture Calculator
Turn a refractometer reading (moisture % or °Brix) into water content and a fermentation-risk rating. Know if honey is ready to bottle.
Honey Label Generator
Create honey jar labels with net weight, producer info, and required elements. Preview and print for common jars.
Mead Calculator
Work out how much honey to use for a batch of mead at your target ABV and sweetness, with gravity and alcohol estimates.
Pest Management
Varroa Mite Count Calculator
Turn a mite-wash count into mites per 100 bees and a treat-or-monitor answer based on the Honey Bee Health Coalition seasonal thresholds.
Oxalic Acid Dosage Calculator
Size dribble, vaporization (OAV), or extended-release glycerin oxalic acid doses for any number of colonies, based on the EPA product label.
Varroa Treatment Comparison
Compare Varroa mite treatments: pros, cons, temperature ranges, and honey super compatibility. High-level guide, not a label replacement.
