# GIR Calc vs AHA PALS

The clearest difference is review sentiment: GIR Calc at 100% against AHA PALS's 55%. GIR Calc also leads on in-app purchases (none vs 1) and rating (4.8 vs 4.5). AHA PALS's advantage is ratings volume (54 vs 5) and chart position (#158 vs unranked). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AHA PALS sells 1 in-app purchase, starting at $3.99 per year. GIR Calc asks for nothing beyond the download.

GIR Calc holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: AHA PALS has 54 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 100% of GIR Calc's written reviews are positive against 55% of AHA PALS's.

GIR Calc ships an update every 4 months, AHA PALS every 2 months. The most recent releases landed on October 20, 2026 and October 27, 2026 respectively.
