# LawStack vs CFR AI

The clearest difference is monetization model: LawStack at free with in-app purchases against CFR AI's subscription. LawStack also leads on ratings volume (379 vs 1) and update cadence (fortnightly vs every 2 months). CFR AI's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. LawStack sells 34 one-off in-app purchases and CFR AI sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

CFR AI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LawStack has 379 ratings behind it against 1, so its average is the more settled of the two.

LawStack ships an update fortnightly, CFR AI every 2 months. The most recent releases landed on October 14, 2026 and October 15, 2026 respectively.
