Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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