# Altimeter GPS Elevation vs Zip Viewer

Altimeter GPS Elevation and Zip Viewer are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Altimeter GPS Elevation sells 1 in-app purchase, starting at $4.99 per 7 days and Zip Viewer sells 4 in-app purchases, starting at $0.69 per month. Whichever you choose, the download price is not the number that matters.
