Verdict
The clearest difference is review sentiment: ToolScanner at 100% against Spoolstock's 48%. Spoolstock's advantage is rating (4.5 vs 4.0) and update cadence (weekly vs every 3 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. Spoolstock sells 2 in-app purchases, starting at $1.99 per month and ToolScanner sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Spoolstock holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Spoolstock has 115 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 48% of Spoolstock's written reviews are positive against 100% of ToolScanner's, so the app with the better star average is not the one people write more warmly about.
Spoolstock ships an update weekly, ToolScanner every 3 months. The most recent releases landed on September 21, 2026 and July 9, 2026 respectively.
