# Graphwar II vs Ohmie

The clearest difference is price: Ohmie at Free against Graphwar II's $4.99. Ohmie also leads on ratings volume (247 vs 3) and rating (4.5 vs 4.3). Graphwar II's advantage is review sentiment (100% vs 56%) and in-app purchases (none vs 4). On device support there is nothing between them.

Ohmie is free to download; Graphwar II costs $4.99 up front. Ohmie sells 4 in-app purchases, starting at $7.99 per month. Graphwar II asks for nothing beyond the download.

Ohmie holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Ohmie has 247 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Graphwar II's written reviews are positive against 56% of Ohmie's, so the app with the better star average is not the one people write more warmly about.

Graphwar II ships an update every 2 days, Ohmie every 3 days. The most recent releases landed on October 9, 2026 and October 18, 2026 respectively.
