# planlauf/TERRAIN vs Detector Maps

The clearest difference is rating: Detector Maps at 4.7 against planlauf/TERRAIN's 2.5. Detector Maps also leads on update cadence (every 6 days vs every 6 weeks) and ratings volume (248 vs 2). planlauf/TERRAIN's advantage is monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. planlauf/TERRAIN sells 15 one-off in-app purchases and Detector Maps sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Detector Maps holds the better App Store score, 4.7 against 2.5. That said, the two scores are not equally well evidenced: Detector Maps has 248 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of planlauf/TERRAIN's written reviews are positive against 73% of Detector Maps's, so the app with the better star average is not the one people write more warmly about.

planlauf/TERRAIN ships an update every 6 weeks, Detector Maps every 6 days. The most recent releases landed on September 7, 2026 and September 24, 2026 respectively.
