# Voltage Regulator vs CtRWCampRobotControl

The clearest difference is in-app purchases: CtRWCampRobotControl at none against Voltage Regulator's 1. CtRWCampRobotControl also leads on rating (5.0 vs 4.8). Voltage Regulator's advantage is ratings volume (5 vs 1). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Voltage Regulator sells 1 one-off in-app purchase. CtRWCampRobotControl asks for nothing beyond the download.

CtRWCampRobotControl holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Voltage Regulator has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
