Verdict
Calculator and Bluetooth Tracker both sit at 4.4 stars, but that hides the real split: 100% of Calculator's written reviews are positive against 0% of Bluetooth Tracker's. Calculator also leads on in-app purchases (none vs 4). Bluetooth Tracker's advantage is ads (none vs shown) and ratings volume (40 vs 8). On price, rating, update cadence 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. Bluetooth Tracker sells 4 in-app purchases, starting at $6.99 per 7 days. Calculator asks for nothing beyond the download.
Bluetooth Tracker holds the better App Store score, 4.5 against 4.4. That said, the two scores are not equally well evidenced: Bluetooth Tracker has 40 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 100% of Calculator's written reviews are positive against 0% of Bluetooth Tracker's, so the app with the better star average is not the one people write more warmly about.
Calculator ships an update every 3 weeks, Bluetooth Tracker every 5 weeks. Both last shipped on October 24, 2026.
