Verdict
The clearest difference is rating: Tinker DIY at 4.7 against GWSCAN's 4.3. Tinker DIY also leads on monetization model (ad-supported vs paid) and update cadence (every 2 weeks vs every 2 months). GWSCAN's advantage is review sentiment (59% vs 44%) and iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

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 4.3. That said, the two scores are not equally well evidenced: Tinker DIY has 1.8K ratings behind it against 83, so its average is the more settled of the two. Written reviews complicate that: 44% of Tinker DIY's written reviews are positive against 59% 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 2 weeks, GWSCAN every 2 months. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
