# Rigibi vs Gradient Sort

The clearest difference is review sentiment: Rigibi at 100% against Gradient Sort's 42%. Rigibi also leads on rating (5.0 vs 4.5) and ads (none vs shown). Gradient Sort's advantage is update cadence (weekly vs every 32 months) and ratings volume (4.6K vs 4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Rigibi sells 1 one-off in-app purchase and Gradient Sort sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
