# Maxwell's Equations App vs CELT

The clearest difference is in-app purchases: Maxwell's Equations App at none against CELT's 10. Maxwell's Equations App also leads on iOS requirement (7.0 vs 15.5). On price, ads and device support there is nothing between them.

Both are free to download. CELT sells 10 one-off in-app purchases. Maxwell's Equations App asks for nothing beyond the download.
