# Cerebo vs JustFlip

The clearest difference is in-app purchases: Cerebo at none against JustFlip's 3. Cerebo also leads on ratings volume (6 vs 1). JustFlip's advantage is update cadence (every 6 days vs every 2 weeks). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. JustFlip sells 3 in-app purchases, starting at $1.99 per month. Cerebo asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Cerebo against 5.0 for JustFlip. That said, the two scores are not equally well evidenced: Cerebo has 6 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.

Cerebo ships an update every 2 weeks, JustFlip every 6 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
