The Historic Map Builder is here.

Go back in time. Over 250,000 town and city maps from the late 1800s through 1930, available to download and place over the modern map yourself. Line one up against today's terrain and see the streets, buildings and lots that are gone. Sheets other members have placed show up on your map too.

Also in this version:

• Sign in with Apple — one tap, no password, no email code
• Redesigned onboarding that actually shows you what the app does
• 3D map markers that stand on the ground and stay visible at any tilt
• New location arrow with a course-up mode — tap the locate button twice and the map turns with you as you walk
• Much finer track recording, so tight grids and turn-arounds draw the way you actually walked them
• Offline coverage outlines so you can see exactly where your downloaded maps end
• Better 3D terrain, online and off
• Faster offline downloads with accurate size estimates before you start

Bug fixes and performance improvements throughout.
