# PepPedia vs SpicyCalc

The clearest difference is rating: SpicyCalc at 5.0 against PepPedia's 3.6. PepPedia's advantage is ratings volume (77 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PepPedia sells 2 in-app purchases, starting at $6.99 per month and SpicyCalc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SpicyCalc holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: PepPedia has 77 ratings behind it against 1, so its average is the more settled of the two.

PepPedia ships an update every 6 days, SpicyCalc every 4 days. The most recent releases landed on November 12, 2026 and October 31, 2026 respectively.
