Verdict
The clearest difference is update cadence: PepPedia at every 2 days against PepGuide's every 3 weeks. PepPedia also leads on review sentiment (53% vs 33%) and ratings volume (63 vs 14). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PepPedia sells 2 in-app purchases, starting at $6.99 per month and PepGuide sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
PepGuide holds the better App Store score, 3.9 against 3.7. Both are backed by a comparable volume of ratings — 63 and 14 respectively. Written reviews complicate that: 53% of PepPedia's written reviews are positive against 33% of PepGuide's, so the app with the better star average is not the one people write more warmly about.
PepPedia ships an update every 2 days, PepGuide every 3 weeks. The most recent releases landed on September 23, 2026 and September 18, 2026 respectively.
