# Subnet Plus vs GV

The clearest difference is rating: Subnet Plus at 4.7 against GV's 3.0. Subnet Plus also leads on review sentiment (89% vs 50%) and update cadence (monthly vs every 8 months). GV's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, monetization model and device support there is nothing between them.

Both are free to download. Subnet Plus sells 1 one-off in-app purchase. GV asks for nothing beyond the download.

Subnet Plus holds the better App Store score, 4.7 against 3.0.
