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.

Bytefall goes through your photo library and shows you what is taking up the space — with the real number, measured, after the scan. Nothing is claimed before it has been counted. WHAT IT FINDS • Exact duplicates — byte-for-byte identical copies of the same file • Similar shots — the burst of eight where you only wanted one • Screenshots — with a choice of how old: 7, 15, 30, 60 or 90 days, or all of them • Photos saved from other apps — messages, downloads, anything that did not come from your camera • Large videos — the handful of files that quietly hold most of your storage • Out-of-focus photos — optional, and off until you turn it on Every category shows how many items and how many megabytes before you decide anything. THREE WAYS TO REVIEW • Quick Sweep — one screen, the safe categories, one decision • Sets — duplicates and similar shots arrive as a group, with one kept and the rest marked • Swipe or grid — one photo at a time, or many at once with checkboxes Everything you mark goes to a basket first. Nothing is deleted until you confirm, and the basket survives closing the app, so a review of eighty sets does not have to be finished in one sitting. WHAT IT WILL NOT TOUCH Favourites, anything from the last seven days, photos in shared albums, photos you have edited, and any source you exclude are left alone. The suggested keeper in a set is a suggestion, not a verdict — you can move it. HONEST NUMBERS Storage Truth shows the free space you have now and the free space you will have afterwards, read from the device. Categories overlap — the same photo can be a duplicate and a large file at once — so the headline figure counts each photo once. An app that finds "9 GB" and frees 4 GB is doing arithmetic in its own favour. On iPhone, deleted items move to Recently Deleted and hold their space for thirty days, so the figure arrives when that album is emptied. Bytefall says so on that screen, before you confirm, rather than showing a number the phone will not honour yet. And if iCloud Photos is on, a deletion here reaches every device signed in to the same account. WHY BYTEFALL ASKS FOR ACCESS TO YOUR WHOLE LIBRARY Finding a duplicate means comparing every photo against every other photo. A picker that returns a handful of hand-picked files cannot answer the question the app exists to answer — you would have to already know which photos are duplicates in order to select them. Access is used for that comparison and nothing else. YOUR PHOTOS STAY ON YOUR PHONE No account. No sign-in. Your photos are read, compared and deleted entirely on the device. They are never uploaded — there is no server behind this app to upload them to. The app is free and shows one full-screen ad when a scan finishes — at the seam between the work and the result, never over the grid, the swipe deck or the basket, where a stray tap would cost a photograph. A single purchase removes it for good. Designer 2 j.d.o.o.
