M2go Sensor vs Calccis

The M2go Sensor application works as a bluetooth smart sensor interface for the Measure2go hardware by taskit. This application lets you set up and calibrate the sensor nodes. It can store the displayed real time measurement values or download logged data over bluetooth to your mobile device. The stored data can then be exported. The connection to the Measure2go accessories is established via Bluetooth Smart (aka: Bluetooth Low Energy). Features: - Supports the following Measure2go sensors: Blue pH-Meter, Blue RTD, Blue LoopRX, Blue LoopTX - Download of logged data from sensor - Manual storage of measurement values - Change sensor configuration - Wireless communication with the sensor nodes over Bluetooth Low Energy (BLE) Display: The sensor value readings can be viewed in real-time including: - The unique sensor node ID - Digital sensor value display in any unit - Last stored measurement value with timestamp - Last calibration with slope, offset and date (on "Info" page) - Trigger to shot the current sensor value manually Storage / transfer: All stored readings (sensor values, pH, voltage, temperature, location and time) can be exported by e-mail or via iTunes as a csv file. This file can be imported to (nearly) any spreadsheet programm on the PC and then be viewed in a table. Compatibility: Requires iOS 9.0 or later. Compatible with iPhone, iPad and iPod touch.

Calccis is a reverse polish notation (RPN) calculator. It supports basic arithmetic, trigonometrical, logarithm and exponent calculations for real, fractional, and complex numbers. Degrees and radians can be used for trigonometrical functions. You can perform matrix calculations, too. There is an undo stack, which supports undoing and redoing the 100 latest operations. Calccis does not copy or mimic any existing physical calculators. However, the operation of the stack has been influenced by how the stack works in the 1990s Hewlett-Packard HP-48 family of calculators.
