Verdict
The clearest difference is rating: Number Book at 4.2 against Crew Tools.Net's 3.5. Number Book also leads on ratings volume (371 vs 13). Crew Tools.Net's advantage is in-app purchases (none vs 4) and review sentiment (20% vs 0%). On price, update cadence, ads and device support 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. Number Book sells 4 in-app purchases, starting at $8.99 per 7 days. Crew Tools.Net asks for nothing beyond the download.
Number Book holds the better App Store score, 4.2 against 3.5. That said, the two scores are not equally well evidenced: Number Book has 371 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 20% of Crew Tools.Net's written reviews are positive against 0% of Number Book's, so the app with the better star average is not the one people write more warmly about.
Crew Tools.Net ships an update every 2 weeks, Number Book every 3 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
