Nestik

Nestik turns bare willow rods into a thriving garden structure and guides you through every step of the journey. Design a tunnel, dome, fedge, wigwam, arbour, or pavilion, then watch a three-year growth simulation unfold month by month on your screen. Tell Nestik about your ground — soil type, moisture level, and daily sun hours — and choose from eight real willow varieties. The built-in growth engine calculates exactly how many rods to order, how many bundles to buy, and which month your structure will first reach full leaf cover. A detailed month-by-month work plan tells you precisely what to do each season: plant, weave, tie in, prune, and fill gaps on the right schedule for your hemisphere. Track your real structure with monthly photos taken from a fixed viewpoint. Each month, compare your photo side by side with the model prediction and see at a glance whether your willow is ahead of or behind the expected curve. A single tap recalibrates the growth model to match your actual observations, keeping all future forecasts accurate to your conditions. A built-in reference library covers all eight structural forms, eight willow varieties, nine essential tools, seven seasonal tasks, and eight common problems — everything you need to plan, build, and maintain a living willow structure from first planting to full canopy. All features work completely offline, with no account or subscription required.
