# Pocket Heart vs PCR

The clearest difference is in-app purchases: PCR at none against Pocket Heart's 2. PCR also leads on update cadence (every 2 weeks vs every 11 months) and rating (5.0 vs 4.7). Pocket Heart's advantage is ratings volume (492 vs 3) and device support (3 vs 1). On price and ads there is nothing between them.

Both are free to download. Pocket Heart sells 2 in-app purchases, starting at $0.99 per month. PCR asks for nothing beyond the download.

PCR holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Pocket Heart has 492 ratings behind it against 3, so its average is the more settled of the two.

Pocket Heart ships an update every 11 months, PCR every 2 weeks. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
