# E3 ES vs Multica Go

The clearest difference is in-app purchases: E3 ES at none against Multica Go's 4. Multica Go's advantage is update cadence (every 2 days vs every 3 weeks) and ratings volume (7 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Multica Go sells 4 in-app purchases, starting at $0.99 per month. E3 ES asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for E3 ES against 4.9 for Multica Go. That said, the two scores are not equally well evidenced: Multica Go has 7 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.

E3 ES ships an update every 3 weeks, Multica Go every 2 days. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
