# Elevation Survey vs 勾配換算

The clearest difference is in-app purchases: 勾配換算 at none against Elevation Survey's 2. Elevation Survey's advantage is ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.

Both are free to download. Elevation Survey sells 2 in-app purchases, starting at $6.99 per month. 勾配換算 asks for nothing beyond the download.
