NectarIndex vs Apiary Tools

NectarIndex — Your Bloom Forecast Companion Are you a beekeeper wondering when the acacia, linden, or chestnut will bloom in your area? NectarIndex helps you anticipate nectar flow seasons so you can plan hive moves, honey supers, and inspections with confidence. The app uses real weather data from your location to calculate Growing Degree Days (GDD) from the start of the year, estimating the phenological stage of over 96 nectar-producing plant species. The result is a NectarIndex score — from 0 to 100 — giving you an intuitive read on the nectar potential for each plant in your area. WHAT YOU CAN DO WITH NECTARINDEX • See which plants are about to bloom near you • Track temperature accumulation with Growing Degree Days (GDD) • Use the bloom calendar to plan your season • Manually select any location on the map • Filter plants by Köppen climate zone • Explore a database of 96 nectar plant species across Europe and North America • Check integrated weather forecasts for the coming days BUILT FOR BEEKEEPERS EVERYWHERE NectarIndex includes both European and North American nectar species, with automatic continent detection based on your location. Whether you're in Italy, France, Germany, or the United States, you'll find the most relevant plants for your area. HOW IT WORKS The algorithm is based on Growing Degree Days (GDD), a well-established scientific method used in agronomy and phenology. Each species has a thermal bloom threshold: when the GDD accumulated at your location reach that threshold, the plant is approaching bloom. NectarIndex combines this with current and forecast weather conditions to calculate the final score. AN IMPORTANT NOTE NectarIndex is a support tool based on mathematical models and weather data. Forecasts are estimates and may vary depending on local conditions, altitude, exposure, and many other factors. The app's predictions are never a substitute for direct hive inspection and field observation. The best beekeeper is still the one who knows their bees! FREE, NO SUBSCRIPTION REQUIRED NectarIndex is free to use. Occasional unobtrusive ads help us keep the app updated and available for beekeepers everywhere.

Apiary Tools is a simple, powerful app for keeping track of your bees. Whether you run one backyard hive or manage dozens across multiple yards, it keeps your records, reminders, and beekeeping math in one place. KEEP A RECORD OF EVERY HIVE Log your apiaries, hives, and queens, and build a full inspection history with notes and photos. See how each colony is doing over time instead of trying to remember it all. INSPECTIONS MADE EASY Record what you saw on each visit: brood pattern, stores, temperament, queen sightings, mite counts, treatments, and more. Log what you treated with and the dose, so the season's treatment history is in the record. Add photos so you can compare a frame week to week. IN YOUR LANGUAGE The whole app works in 21 languages besides English, including Spanish, German, French, Portuguese, Italian, Dutch, Polish, Japanese, Hindi, Arabic, and Hebrew, with proper right-to-left layout. WORKS WITHOUT SIGNAL Bee yards are not known for good reception. Anything you log offline is saved on the device and syncs itself the moment you are back in range. SHARE HIVE ACCESS Give helpers, family members, mentors, or beekeeping partners access to specific hives or apiaries. Let others add inspections, notes, and photos without sharing your login. NEVER MISS A FOLLOW-UP Set reminders for treatments, feedings, and checks, and get a notification when something is due. Stay on schedule through the whole season. KNOW WHAT IS BLOOMING Enter your ZIP or postcode and see your region's beekeeping year: the main flow, the summer dearth, the fall flow, and the forage plants behind each. The forage range map draws the 1, 2, and 3 mile rings your bees actually work, with the acreage inside each.
