Verdict
The clearest difference is in-app purchases: GWSMARTBT at none against TopGuru's 29. GWSMARTBT also leads on review sentiment (48% vs 29%). TopGuru's advantage is rating (3.5 vs 3.3) and chart position (#195 vs unranked). 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. TopGuru sells 20 in-app purchases, starting at $9.99 per month. GWSMARTBT asks for nothing beyond the download.
TopGuru holds the better App Store score, 3.5 against 3.3. That said, the two scores are not equally well evidenced: TopGuru has 404 ratings behind it against 60, so its average is the more settled of the two. Written reviews complicate that: 29% of TopGuru's written reviews are positive against 48% of GWSMARTBT's, so the app with the better star average is not the one people write more warmly about.
TopGuru ships an update every 3 weeks, GWSMARTBT every 5 weeks. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
