Verdict

The call

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.
