# LispPad Go vs CGProto

The clearest difference is in-app purchases: LispPad Go at none against CGProto's 2. LispPad Go also leads on ratings volume (37 vs 2). CGProto's advantage is update cadence (weekly vs every 2 months) and iOS requirement (15.0 vs 17.6). On price, rating, ads and device support there is nothing between them.

Both are free to download. CGProto sells 2 in-app purchases, starting at $1.49 per month. LispPad Go asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for LispPad Go against 5.0 for CGProto. That said, the two scores are not equally well evidenced: LispPad Go has 37 ratings behind it against 2, so its average is the more settled of the two.

LispPad Go ships an update every 2 months, CGProto weekly. The most recent releases landed on October 24, 2026 and October 8, 2026 respectively.
