Compass Map Barometer vs EngineerCalc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Compass Map Barometer
This application provides a digital compass to easily identify cardinal directions and any arbitrary direction. It offers the flexibility to switch between magnetic and true north, and includes a map rotation feature. A barometer function is also available on compatible devices.
- Electronic compass
- Magnetic and true north modes
- Map rotation
- Barometer function
- Designates cardinal directions

EngineerCalc is an app for electrical engineers and hobbyists. At the moment, it includes 4 calculators: • CapacitorCalc - Calculate the ripple voltage refusing capacitor capacitance and min. voltage for your AC-DC circuit • InductorCalc - Calculate the inductance, needed wire-length (and resistance of the wire) and Q-value for your diy coil/inductor • LC-TankCircuit - Calculate the 3rd value of your tank-circuit (capacitance, inductance or frequency) • Ohm'sLawCalc - Calculate the 3rd and/or 4th value of an Ohm's law circuit (voltage, current, resistance or power ) The app supports multiple units which you can change by tapping the unit-label: For CapacitorCalc: • Voltage (Volt) - V • Current (Amper) - A • Frequency (Herz) - Hz For InductorCalc: • Distance (Meter) - µm, mm, cm, m, Km • Resistance (Ohm) - pΩ, nΩ, µΩ, mΩ, Ω, KΩ, MΩ, GΩ • Frequency (Herz) - Hz, KHz, MHz, GHz • Inductance (Henry) - pH, nH, µH, mH, H, KH, MH, GH For LC-TankCircuit: • Capacitance (Farad) - pF, nF, µF, mF, F, KF, MF, GF • Inductance (Henry) - pH, nH, µH, mH, H, KH, MH, GH • Frequency (Herz) - Hz, KHz, MHz, GHz For Ohm'sLawCalc: • Voltage unit (Volt) - pV, nV, µV, mV, V, KV, MV, GV • Current unit (Amper) - pA, nA, µA, mA, A, KA, MA, GA • Resistance unit (Ohm) - pΩ, nΩ, µΩ, mΩ, Ω, KΩ, MΩ, GΩ • Power unit (Watt) - pW, nW, µW, mW, W, KW, MW, GW If you have an development suggestion, want to request an unit support or want to report a bug, you can get in touch with me trough my website https://ssl-saario.xyz/AppFiles/html/eCalcHelp.html

Verdict
The clearest difference is price: Compass Map Barometer at Free against EngineerCalc's $1.99. Compass Map Barometer also leads on update cadence (every 7 months vs every 60 months). EngineerCalc's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
