LZonePRO

LZonePRO is a gardener's tool for planning plant hardiness zones and frost. The app determines your growing location's zone based on the annual minimum temperature, calculates the length of the frost-free period from the first and last frost, and assesses whether the plants you want are suitable for the location as is or with protection. You can adjust latitude, altitude, minimum temperature, plant zone and the amount of protection with sliders: the zone meter, temperature curve and frost timeline update instantly. All data is stored on your device, so the app requires no internet connection or registration and does not collect your data. The Pro version is unlocked with a one-off payment, with no ads or subscription.
