Terragrid – Explore the Real World Turn the real world green, one place at a time. Terragrid turns your everyday movement into a game of discovery. The map starts fully red. Every place you physically visit unlocks its cell and turns it green. Walk a new street, travel to a new city, or fly to a new country, and watch your personal map of the planet fill in over time. It all happens automatically. Terragrid quietly detects the places you visit in the background, so you can simply live your life and come back to see how much of the world you have explored. WHY YOU'LL LOVE IT • A living map of your life. Watch red turn to green everywhere you go. • Automatic discovery. New cells unlock in the background as you move—no check-ins required. • Real progress. Every street, city, and country you visit is tracked from real location data, never faked. • A pixel world map. See the share of the entire planet you have explored at a glance. • Daily activity. Review your steps, new cells, and the path you walked each day. • Achievements. Earn badges as you go, from your very first cell to true globetrotter. • Beautiful and private. A clean, colorful design with all of your exploration data stored on your device. HOW IT WORKS 1. Allow location access so Terragrid can see where you go. 2. Head outside and explore as you normally would. 3. Open the app to watch new cells turn green and your stats grow. TERRAGRID PLUS Upgrade to Terragrid Plus to get the most out of your exploration: • Unlimited exploration with no daily cap on new cells. • Worldwide statistics and advanced insights. • Shareable maps to show friends how far you have explored. • Premium map themes. Terragrid Plus is available as an auto-renewing subscription. Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period. You can manage and cancel your subscription in your App Store account settings after purchase. YOUR PRIVACY MATTERS Terragrid is built to respect your privacy. Your visited map and location history are stored on your device. We do not sell your data. Location is used only to power the core feature of unlocking the places you visit, including in the background so discoveries are not missed while the app is closed. Start exploring today and see how much of the world you can turn green.

Verdict
The clearest difference is in-app purchases: SkyDot at none against Terragrid's 2. SkyDot also leads on device support (3 vs 1) and iOS requirement (15.1 vs 18.6). Terragrid's advantage is ads (none vs shown). On price and update cadence there is nothing between them.
