Name any of 31 common trees by leaf, bark and habitat — no photo, no signal needed. Log every sighting on your walks. Name the tree in front of you — by leaf, bark and habitat, no photo required. Most tree apps ask you to point a camera and trust an AI guess. Bole works the way a field guide works: you look at the leaf, check the bark, note where the tree is growing, and the key walks you to the answer. You learn to see the tree, not just get a label for it. Every species page tells you exactly what to look for, and the whole catalogue lives on your phone — no signal, no account. WHAT YOU GET • Put a name to 24 common trees of Europe and North America, from English Oak and Sugar Maple to Douglas Fir and Ginkgo • Narrow the field in seconds with the Leaf Key — lobed, pinnate, palmate, needled or simple • Know which species to expect in each terrain: deciduous forest, conifer, urban, wetland or mountain • Confirm the ID with bark, height and leaf detail written for eyes, not algorithms • Keep a Spotted log of every tree you find, with the date, the place and your own notes • Identify deep in the woods with zero reception — the full catalogue works offline PERFECT FOR • Walkers and hikers who keep asking "what tree is that?" • Parents and teachers turning a park walk into a nature lesson • Students of botany, forestry and arboriculture learning the key features • Anyone who wants to know the trees on their own street by name WHY NOT JUST SNAP A PHOTO? Camera apps give you a name and teach you nothing — and they fail on bare winter branches, on distant canopies and with no signal. Bole teaches you the three tells that professionals use: leaf shape, bark texture and habitat. After a few walks you will recognise a beech or a rowan before you even open the app. PRIVATE BY DEFAULT Your sighting log is stored on your device and nowhere else. Bole has no account, no cloud sync and no tracking. It does not ask for your location or your camera. FULL ACCESS Bole is unlocked with a subscription. Choose a weekly, yearly, or lifetime plan, cancel any time from your Apple ID settings. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase. Download Bole, open the Leaf Key on your next walk, and name the first tree you pass.
