# iAltair vs Touch Lua +

The clearest difference is rating: iAltair at 4.8 against Touch Lua +'s 3.7. iAltair also leads on in-app purchases (none vs 3) and ratings volume (22 vs 3). Touch Lua +'s advantage is update cadence (every 5 months vs every 11 months) and iOS requirement (7.0 vs 15.4). On price, review sentiment and ads there is nothing between them.

Both are free to download. Touch Lua + sells 3 one-off in-app purchases. iAltair asks for nothing beyond the download.

iAltair holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: iAltair has 22 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 75% and 75% positive.
