CombLogic Apiary turns conflicting seasonal advice into four numbers you can act on today: varroa percent versus threshold, swarm risk, projected autumn mite load, and harvest yield. Treatment windows and withdrawal countdowns are tracked automatically. Everything works offline, with no account required.
WHO IT IS FOR
Backyard beekeepers, sideliners, apiary-club members, and anyone in their first two seasons who wants a straight answer instead of another logbook.
VARROA DIAGNOSTICS
Record alcohol wash, sugar roll, sticky-board 24-hour drop, and 100- or 300-bee samples. CombLogic converts raw counts to an infestation percentage, compares it with the seasonal threshold for the month, and adds a sample-confidence note so you know how much to trust the result. A Canvas mite-growth ribbon projects weekly exponential growth per hive and places a "do nothing" line beside a treatment-start scenario, with threshold band shading and alarm markers past 2–3%.
TREATMENT WINDOWS AND WITHDRAWALS
Plan rotations by active-ingredient class — formic, oxalic, thymol, amitraz, hop beta acids — with temperature windows, resistance-class history, super-on legal labels, and honey-withdrawal day countdowns, so you never miss the last legal window before supers go on.
SWARM AND QUEEN PLANNING
A swarm-readiness radar scores brood-nest space, congestion, queen-cell sightings, season, and nectar flow, then auto-generates prep tasks when risk rises. The queen planner follows queen age, brood pattern, supersedure and drone-layer signals, and suggests a requeen window per hive.
FORAGE, FEEDING, HARVEST
A nectar-flow calendar uses seeded regional bloom windows with dearth warnings and a feeding-syrup ratio calculator matched to dearth intensity. The harvest lab converts refractometer Brix to moisture percentage, turns super weight delta into honey weight, and estimates jar count by jar size.
INSPECTIONS AND REMINDERS
Guided inspection checklists adapt to the season, with one-tap severity rows and CameraX frame photos attached to each hive. WorkManager reminders and a Glance home-screen widget show due inspections, open treatment windows, and the day's temperature band.
YOUR DATA, YOUR DEVICE
Room-backed offline storage, DataStore units, thresholds and region settings, plus CSV and PDF-style season report export through the share sheet for club meetings. Optional Open-Meteo caching keeps forecasts available with no network.
No sign-up. Your hive records stay on your device.
