BeeLine Reader vs DB48X

Read faster and more easily with our digital reading technology, which has has won awards from Stanford and United Nations! Here's how it works: instead of using plain black text, we display text using eye-guiding color gradients. These gradients flow from the end of one line to the beginning of the next, so that when you move your eyes from right to left, they're automatically drawn to the appropriate line. Vision, literacy, and medical experts agree that BeeLine Reader improves reading speed and reading ability for readers of all ages and skill levels. It is particularly helpful for readers with dyslexia, ADD, or vision impairments—some readers are able to read over 50% faster with BeeLine. Find out how much it will help you by taking the BeeLine Reading Challenge on our website: www.BeeLineReader.com. Included app functionality: Read with BeeLine in Safari using our BeeLine Action Extension; save articles for later using the BeeLine Share Extension; and browse the web with BeeLine on select popular websites (AP News, Reuters, and Medium.com) within the BeeLine app. Never used an extension before?

DB48X is a new high-precision scientific calculator inspired by the legendary HP48 series from Hewlett-Packard. It is not an emulator, but a redesign from scratch, which is faster, and delivers never seen before capabilities like computations in arbitrary precision. Like the original HP48, DB48X supports an unlimited stack, RPN and algebraic operations, complex numbers, based numbers, vectors, matrices, text, symbolic computations, numerical solving and integration, graphing and plotting, statistics, engineering units, and well over 1000 built-in functions. DB48X adds several HP50G capabilities, including a library of equations and constants covering mathematics, physics or chemistry. Using modern technologies, DB48X goes well beyond the original HP48 in many ways: - It is significantly faster, uses less memory, and features a higher-resolution 240x400 pixels graphical display. - Integer and decimal values can have an arbitrarily large number of digits, so you can compute log(pi) with 200 digits in a few keystrokes. - The six function keys feature up to three function per key, giving quick access to up to 18 related functions at a time. - Complex numbers can mix and match polar and rectangular form. - Symbolic operations extend to complex numbers, vectors and matrices. - Based numbers can be in any base from 2 to 36, and support any number of bits, making it easy to emulate a 23-bit or 512-bit processor. - Text is represented using Unicode instead of the proprietary HP encoding, facilitating data exchange with the rest of the world. - Multiple graphs can be distinguished using bitmap patterns (DB50X adds the ability to use colors) - Engineering units include all the modern evolutions of the SI system, and can be configured by the user, e.g. to integrate currency units with the exchange rate du jour. Converting between USD/hour and EUR/day has never been so easy! - A built-in hyperlinked help system documents functions simply by holding the corresponding key, and combine a quick start guide, a user manual and a reference manual. DB48X will run many user RPL programs as is. However, since it is not an emulator, it will not run any HP binary object, and notably will not run HP48 games or anything involving system RPL. DB48X is part of a family of compatible RPL calculators that include the free DB40X and the color DB50X.
