# Pro Cal vs Supplement Stack

Pro Cal and Supplement Stack both sit at 4.8 stars, but that hides the real split: 100% of Supplement Stack's written reviews are positive against 36% of Pro Cal's. Supplement Stack also leads on monetization model (freemium vs subscription) and update cadence (every 4 days vs every 2 weeks). Pro Cal's advantage is ratings volume (14K vs 3) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Pro Cal sells 10 in-app purchases, starting at $6.99 per 7 days and Supplement Stack sells 4 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Supplement Stack holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Pro Cal has 14K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 36% of Pro Cal's written reviews are positive against 100% of Supplement Stack's.

Pro Cal ships an update every 2 weeks, Supplement Stack every 4 days. Both last shipped on November 13, 2026.
