# Stackby vs CFR 19

The clearest difference is rating: CFR 19 at 5.0 against Stackby's 4.3. Stackby's advantage is in-app purchases (none vs 3) and update cadence (every 6 weeks vs every 12 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. CFR 19 sells 3 one-off in-app purchases. Stackby asks for nothing beyond the download.

CFR 19 holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Stackby has 42 ratings behind it against 1, so its average is the more settled of the two.

Stackby ships an update every 6 weeks, CFR 19 every 12 months. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
