# The Four vs Impossible Charge

The clearest difference is ads: The Four at none against Impossible Charge's shown. The Four also leads on ratings volume (163 vs 25) and iOS requirement (6.0 vs 15.0). Impossible Charge's advantage is update cadence (every 5 weeks vs every 13 months) and rating (4.2 vs 4.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Impossible Charge holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: The Four has 163 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 66% of The Four's written reviews are positive against 59% of Impossible Charge's, so the app with the better star average is not the one people write more warmly about.

The Four ships an update every 13 months, Impossible Charge every 5 weeks. The most recent releases landed on October 6, 2026 and October 13, 2026 respectively.
