User reviews

Even if you’re not a surveyor

First of all, this app has a beautifully executed and intuitive user interface. IMO, everybody, even if they never leave the city, need to know the basics of how to use a map and compass. If a 12 year old Boy Scout can, so can you. It might even save your life one day.
This tool is so easy and pleasant to use that practically anyone who took middle school geometry will know how to use it without even looking at the help. But “what use could I possibly have for it ?” you ask. Look around, you’ll see. If nothing else it’s a fun way to help a kid understand geometry, which is essential knowledge, like knowing how to add and subtract.
