# ABA Pocketbook vs TallyFlex

The clearest difference is in-app purchases: ABA Pocketbook at none against TallyFlex's 2. ABA Pocketbook also leads on iOS requirement (12.0 vs 15.0). TallyFlex's advantage is rating (4.3 vs 3.8) and update cadence (every 10 days vs every 2 months). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. TallyFlex sells 2 in-app purchases, starting at $27.99 per month. ABA Pocketbook asks for nothing beyond the download.

TallyFlex holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: TallyFlex has 88 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 71% of ABA Pocketbook's written reviews are positive against 64% of TallyFlex's, so the app with the better star average is not the one people write more warmly about.

ABA Pocketbook ships an update every 2 months, TallyFlex every 10 days. The most recent releases landed on October 6, 2026 and October 16, 2026 respectively.
