# Simple TOPO vs OpenMaps

The clearest difference is review sentiment: Simple TOPO at 100% against OpenMaps's 10%. Simple TOPO also leads on rating (5.0 vs 3.9) and ads (none vs shown). OpenMaps's advantage is update cadence (every 2 months vs every 51 months) and ratings volume (16 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Simple TOPO sells 2 in-app purchases, starting at $2.99 per month and OpenMaps sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
