►► Gaia GPS & GaiaPro Subscriptions
Offline Topo Maps will work beautifully without upgrades, but you also can upgrade to the full version of Gaia GPS from within Offline Topo Maps. From there, you could also buy a GaiaPro subscription. GaiaPro costs 3.99/month or 39.99/year.

• TURN OFF auto-renewal via the main Settings app:

• Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period. Your iTunes account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal.

• Payment will be charged to iTunes Account at confirmation of purchase

Warning: Continued use of GPS running in the background can dramatically decrease battery life.

• Improved Left Menu on iPhone (not iPad)
• 3D-Touch support - On the map, and saved screens.
• of all the unlikely crashes in Offline Topo Maps, this release should fix about half of them, and we expect what was once a stable app, is now even stabler

▶ Map Source Menus
• The menus where you choose map sources and add map sources have been improved
• Map sources in your list now use an icon based on the exact map - different for each
• You can now view a details screen about map sources in the app - includes a demo map, zoom range, description, and attribution
• Added a description for each map source - have fun browsing tons of maps of the world and history
• Remove default sources - you can now remove even default sources the app starts with, and customize your map layers perfectly (many people have requested this)
• Manage imported sources - view/add/remove sources you imported via the Add Map Sources screen too

▶ Localization
• Re-did localization for all languages, added Turkish translation

Best app I own... For all my travels

I got this years ago on an iPod touch for free, but would gladly pay $50 for it. We do a lot of traveling, mostly local but occasionally abroad, and use it no matter what! Obviously there is no usgs topo maps for Peru, but you can download street maps for anywhere in the world! Locally, we use this all the time! Simply download maps to an area we know we're exploring and go to the wilderness. We're able to pre-route trips, track hikes, and place geotagged pics along the way! This app has been a sort of journal map of my life!

Love the App

This app has been exactly what I hoped for. It lets me download maps while I'm at home on my wifi and then I can access them when in the backcountry. The GPS on my iPad even works when I have no service and shows my location on my topo map. I have not had a problem with the maps at all. I'm glad I bought them.

Great app! Must have for hikers and backpackers

Used this app for almost every hike and backpacking trip I've been on. Highly recommend and looking forward to see newer and more detailed map additions. Thanks!
