# BlueTools Bluetooth Assistant vs Programmer Calculator

The clearest difference is rating: Programmer Calculator at 4.6 against BlueTools Bluetooth Assistant's 3.5. Programmer Calculator also leads on ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). BlueTools Bluetooth Assistant's advantage is review sentiment (64% vs 42%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. BlueTools Bluetooth Assistant sells 2 in-app purchases, starting at $0.99 per month and Programmer Calculator sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Programmer Calculator holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: Programmer Calculator has 32 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 64% of BlueTools Bluetooth Assistant's written reviews are positive against 42% of Programmer Calculator's, so the app with the better star average is not the one people write more warmly about.

BlueTools Bluetooth Assistant ships an update every 6 weeks, Programmer Calculator fortnightly. The most recent releases landed on September 22, 2026 and September 23, 2026 respectively.
