DiscoverSearch and Saga
Look up any living thing and add it to your saga.
Everything you keep, gets a story.
Threads are a way of keeping your posts alive and progress pictures or memorable visits at the top of your mind. Each time you add a post to your Grein, you're adding a category in your life to the page. As you come back to that category — whether it's a place, a house plant, or the tomato plants in your garden — snag a quick picture and a note to add to the thread, and watch the journal grow!
Every photo starts a thread. Add one to anything — a growing house plant, an oak on your street, a catch from your fishing loop, even a sky you won't see again. Add another next week and it stacks underneath, newest on top. Your feed keeps changing with the world you notice around you, and it's completely your own.
A quieter, more private way of digital media for storing and reminiscing on your outdoor adventures. No likes to count. No posting pressure — your feed grows as you do, in the activities you love to do most.
You don't need a mountain to use the map.
Grein puts the whole planet in your pocket, rendered in true 3D — ridgelines, valleys, waterways, and elevation brought to life so you can read the terrain before you ever step into it. Heading somewhere without signal? Download a 50 km area before you go, and your map, saved pins, compass, and recorded routes keep working completely offline. Drop pins wherever something matters, sort them with color-coded categories, and record your trail while the app is open so you can always find your way back.
Something looking sick? Ask the clinic.
Is your houseplant sick, or the tree in your backyard looking nearly dead? Use the clinic to scan your foliage and see what's wrong with it. The clinic lists the likely problems, most probable first, each with a confidence score and treatment steps, and gives you an overall health percentage.
Try it out — your 7-day free trial includes 2 clinic visits to start.
Plan your beds before you plant them.
Sketch each bed on a square-foot grid — name them, set the rows and columns, and fill them from a tray of plants. As you place things, Grein flags good and bad neighbours, and each plant can carry its spacing and sun needs. It all auto-saves, so your plan is ready the next time you're out in the dirt — and when something starts to take off, add it to your Grein to watch it grow through the season.
Your saga, the field guide to the life you've seen.
Watch your saga become the field guide to the life you've seen — you can even tag it on the map! Use our nature database to look up anything living — plants, trees, birds, fish. Then add your searches to your Saga and let the reflection continue!
Notice it. Keep it. Come back to it.
Scan
Point your camera at a plant. Grein names it and tells you what you're looking at — no expertise required. Birds, bugs and fish you can look up in the database.
Pin places
Drop a pin where you found it. Your map fills in with the quiet spots and good trees only you know about.
Saga
Sort your finds into folders and add notes as you go. Your own field guide, built one discovery at a time.
Garden & clinic
Lay out your beds, track each plant's age, and ask the clinic when the leaves start doing something you don't like.
