Verdict
The clearest difference is rating: Technical Pocket Guide (STT) at 5.0 against Kiwix's 4.2. Kiwix's advantage is ratings volume (427 vs 1) and update cadence (every 2 months vs every 9 months). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
Technical Pocket Guide (STT) holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Kiwix has 427 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 55% of Technical Pocket Guide (STT)'s written reviews are positive against 70% of Kiwix's, so the app with the better star average is not the one people write more warmly about.
Technical Pocket Guide (STT) ships an update every 9 months, Kiwix every 2 months. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
