Verdict
The clearest difference is rating: Tinker DIY at 4.7 against GWSCAN's 4.4. Tinker DIY also leads on ratings volume (2K vs 116) and update cadence (every 3 weeks vs every 2 months). GWSCAN's advantage is review sentiment (68% vs 45%) and monetization model (free vs ad-supported). On price, ads, in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Tinker DIY holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Tinker DIY has 2K ratings behind it against 116, so its average is the more settled of the two. Written reviews complicate that: 45% of Tinker DIY's written reviews are positive against 68% of GWSCAN's, so the app with the better star average is not the one people write more warmly about.
Tinker DIY ships an update every 3 weeks, GWSCAN every 2 months. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
