The RLM-Flight app is the ultimate aviation computer. Designed with a clear beautiful interface and easy to use through direct menu selection with all variables at sight converting it in the most powerful, versatile and useful aviation computer you may have in your iOS device. The RLM-Flight has a extensive Menu System: >Altitude & Cloud Base Worksheets: Calculate Pressure Altitude, Density Altitude, Barometric Pressure or Outside Temperature with or without humidity. Also calculates the Cloud Base above ground and Clouds Temperature knowing the Outside Temperature and Dew Point. >Standard Atmosphere: Calculate the Altitude, Temperature or Pressure and the Air Density and Speed of Sound in the International Standard Atmosphere (ISA). > Airspeed Calculations: Calculate the True Air Speed, Calibrated Air Speed, Outside Temperature, Mach number, Total Air Temperature or Pressure Altitude. >Ground Speed & Fuel Rate: Calculate the Ground Speed, Distance, Duration or Fuel consumption. >Glide & Climb/Descent: Calculate Horizontal Distance, Glide Ratio, Descent or Climb Altitude, Angle and Ratio. >Wind Components: Calculate Cross Wind, Head Wind, Run Way, Wind Speed or Wind Direction. >Wind Correction: Calculates the Ground Speed, True Course, True Air Speed, True Heading, Wind Speed or Wind Direction and the Wind Correction Angle. >Compass Heading: Calculate True Heading, Magnetic Heading, Compass Heading, Variation or Deviation. >Holding Pattern & From-To: Calculate the type of entry necessary and the inbound heading to enter in a holding pattern given by the airplane Heading, the Holding Radial and the standard turn (left or right). Also, convert the course from a location into the course to the same location. >Rhumb Line: Calculate the True Course, Rhumb Line Distance and the Great Circle Distance for flight paths specified by latitude and longitude. >Flight Plan: Calculate the Total Distance, Estimated Time in Route, Estimated Time of Arrival and Fuel Burned in a cross country flight composed of an arbitrary number of legs. >Weight & Balance: Calculates the total weight and the resulting center of gravity of an airplane base on the loads arms, weights and/or moments of different items including the empty aircraft weight and center of gravity, pilots, passengers, fuel and cargo areas. >Weight Shift & %MAC: Calculate the change in Center of Gravity, change in Weight, change in Arm or total Weight given the others. Also calculate the %MAC, Center of Gravity, Mean Aerodynamic Chord or Leading Edge of MAC given the others. >Units Conversion: powerful and completely customizable physical units conversion calculations. >Currency Conversion: to calculate currency exchanges between two selected world currencies and common crypto currencies with manual or on-line rates. > Math Functions: to apply scientific functions to the displayed number including angles conversion, trigonometric functions, logarithmic function, decimal hour to hour:minute:seconds, etc. System requirements: iOS 15.0 or above. 30 days Free-Trial.

Pilot Assistant
This app helps flight simulator enthusiasts by providing tools for managing flight files, navigating with airport maps and saved routes, and using a compass for emergency planning. It's designed to assist pilots during training and improve their emergency response skills.
- Save important flight files and checklists
- World airport map with route creation
- Save and mark important radio frequencies
- Compass with markers for emergency planning
- Create and save custom flight routes

Great Tool for Flight Simulator Lovers! This App is designed to assist Pilots during training in Flight Simulators. The App is divided into 3 (three) screens: 1) FILES - Save the Important Files (such as CHECKLISTS) for your flight so you don’t have to look for them every time. You can add any information you need in any of the four sections (any other files that may be useful to you for quick access during the flight) 2) NAVIGATION - Here is a Map with all the Airports of the World. You can create Routes for your Flight, save important radio frequencies and mark the Airports you have passed. For your convenience, you can save your Routes. 3) COMPASS - A compass will be very necessary to work out situations of forced return to the Departure Airport. Engine problems during takeoff are a typical critical situation in which the pilot must act quickly and accurately. By placing markers on the compass, you create a plan of action for certain important stages of the flight. Train, learn and develop your emergency response skills with this Pilot Assistant!

Verdict
The clearest difference is in-app purchases: Pilot Assistant at none against RLM's 1. Pilot Assistant also leads on iOS requirement (11.0 vs 15.0). RLM's advantage is update cadence (every 3 weeks vs every 3 months). On price, rating, ratings volume and ads there is nothing between them.
