Keep a little of everywhere you go. Tabimi is your personal exploration map. Take a walk around your neighborhood or visit a new city. As you move, the fog clears and the places you explore begin to show. Lumi comes along for the journey. MAKE THE MAP YOURS See where you have been, check your explored area and walking distance, and look back at your weekly records. There is always another street to try. COLLECT THE LITTLE THINGS A flower by the road. A coffee on a trip. Take a photo, turn it into a sticker, give it a name, and keep it in your collection. COME HOME TO LUMI After exploring, visit Lumi at home and pick an outfit from the wardrobe. MAKE SOMETHING TO SHARE Create an image of your exploration progress to save or share. Protected areas are hidden from the share image. YOUR DATA AND PRIVACY No account or sign-in is required. Movement tracks and map fog stay on your device. Saved sticker images, names, and capture locations permitted by the privacy rules are stored in Tabimi's cloud. The original camera photo is not saved as a collection item. After a sticker uploads, your phone keeps its thumbnail and downloads the full-size image when needed. Uncached full-size images require an internet connection. Collections cannot currently be restored to another device by signing in. Cloud-assisted recognition and limited product usage statistics can be turned off in Settings. There are no ads or third-party advertising trackers. Bring Lumi on your next walk.

How long is that stretch of river you are about to paddle? Drop two pins and River Ruler measures the riverbed itself, following every bend instead of drawing a straight line. You also get the numbers that decide a trip: where the river starts and ends, how much water it carries, how steep it runs, how winding it is, and how long the section takes by kayak, SUP or on foot. • Measure any river section — along the real riverbed, not a straight line • See the whole river, from source to mouth, with its total length • Find rivers by name, or jump straight to coordinates • Sinuosity, gradient, elevation drop, discharge, basin area, flow direction • Travel time for kayak, SUP or walking • Export as GPX for your GPS, KML for Google Earth, PDF or a ready-to-send image • Saved log of your measurements • Light and dark map styles Built on open OpenStreetMap data.
