How much warmth has accumulated at your location? Grassland Temperature Sum shows a temperature-based guide for beekeepers and gardeners who want to put plant development into context. Choose a location and follow its GTS since January 1. The calculation uses the mean of four daily OpenWeather temperature readings. Positive values count with a factor of 0.5 in January, 0.75 in February and 1.0 from March onwards. Growing Degree Days are also shown, using a base of 10°C/50°F. View the yearly curve and compare it with the previous year when those weather records are available. The bloom calendar lists plants by their stored GTS guidelines for flowering start. The seasons wheel shows a typical Central European calendar reference, not observed seasons at your location. Use the Apple Watch app to view the temperature sum, or the larger iPad view to browse the bloom calendar. You can edit or delete saved locations. Location access and subscriptions New users need a subscription. Annual plans support up to three or ten saved locations. People who bought the app before it became a free download retain access to one location. Available prices and subscription periods are shown in the app. Subscriptions renew automatically unless cancelled. These are calculated weather indicators, not measurements taken by the app or confirmed plant observations. Local conditions, species and sowing dates affect actual flowering. OpenWeather calculations can differ from station measurements. The app does not determine a binding fertilization or sowing date. Choose a location and follow its accumulated warmth.
