# Circuit Simulator vs Ohmie

The clearest difference is ads: Circuit Simulator at none against Ohmie's shown. Circuit Simulator also leads on review sentiment (77% vs 56%) and rating (4.7 vs 4.5). Ohmie's advantage is update cadence (every 3 days vs every 6 weeks) and chart position (#103 vs unranked). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month and Ohmie sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Circuit Simulator holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 87 and 247 respectively. Written reviews point the same way: 77% of Circuit Simulator's written reviews are positive against 56% of Ohmie's.
