BLExAR turns your iPhone or iPad into a pocket bench instrument for Arduino-class boards over Bluetooth Low Energy. Connect to a board with an HM-10 style UART module (CC2541, AT-09, JDY-08, SH-M08), an nRF52840 MakerBLE board or a Seeed XIAO ESP32-C6, then switch pins, stream sensor values, plot and record them, all without writing an app of your own. BLExAR 3.0 is a complete rewrite that keeps working with the sketches and tutorials written for earlier versions: the same commands, the same pins and the same CSV files. CONTROL • Switch digital pins and set PWM from pin tiles laid out like your board's header • Analog sliders for the A-pins • Board profiles for Arduino Uno, Arduino Nano, MakerBLE (nRF52840), Seeed XIAO ESP32-C6 and the classic 2.7 layout • TX/RX activity lights show every message to and from the board DATA • Live chart of the comma-separated values your board sends, with Run/Hold and 10 s, 1 min and 10 min windows • Readout cards with min, max and standard deviation for each series, plus the incoming stream rate • Record sessions to CSV, optionally with your location on each row, and keep recording in the background • Browse, reopen and share recorded sessions; they also appear in the Files app CONSOLE • Serial terminal to send and receive text, with a hex view and quick command keys PANELS • Build your own control dashboards with buttons, toggles, sliders, a joystick and gauges bound to your board's commands and data columns • Share panels with others as files ALWAYS AT HAND • Live Activity on the Lock Screen and in the Dynamic Island while connected or recording • Control Center controls to toggle a pin without opening the app • Scan list puts UART-ready boards first, ordered by signal strength • Automatic reconnect after a dropped link • Light and dark appearance and Dynamic Type BLExAR is made for makers, students, teachers and engineers. Tutorials and example sketches are at makersportal.com.

Verdict

The call

The clearest difference is price: Tinkercad at Free against BLExAR's $4.99. Tinkercad also leads on rating (4.6 vs 4.0) and ratings volume (20K vs 14). BLExAR's advantage is review sentiment (75% vs 59%). On update cadence, ads, in-app purchases and device support there is nothing between them.

Tinkercad is free to download; BLExAR costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Tinkercad holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Tinkercad has 20K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 75% of BLExAR's written reviews are positive against 59% of Tinkercad's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

BLExAR ships an update every 3 months, Tinkercad every 4 months. The most recent releases landed on October 13, 2026 and October 17, 2026 respectively.
