First released in 2009, GoodReader® is truly a veteran of the App Store. In the modern app business, it's not easy to stay relevant that long. We're proud to say that after 17 years and counting, we've been delivering wonderful updates with extraordinary new features. And we're going to keep doing that! GoodReader is a perfect combination of document-reading and file-managing capabilities. It's your one-stop shop for all your document needs on your iOS device. Use the app once, and you'll be hooked. Soon you'll be wondering how you ever managed to work without it. -= File Reading =- PDF, TXT, MS Office, iWork, HTML, pictures, music & audio-books, videos. This is what you can view in GoodReader, plus you can also annotate PDF files and edit TXT files. -= PDF Reading and Annotating =- PDF files is where GoodReader truly shines. Reading experience is so superior, it's hard to describe. To rephrase one of our customers' review, "try it, and you'll see." While you're at it, give our PDF Reflow feature a try. You'll be surprised how much better PDF reading goes when you don't have to scroll left/right all the time, for every single line of text. Annotating PDFs is another star feature of our app. Adding notes and drawings, highlighting text, and then sharing your annotated files or annotation summaries will be your main productivity and collaboration asset. -= File Management =- While reading files is a big part of GoodReader, it's not all it can do. It can also serve as a central hub for all your files, even those that can't be opened by GoodReader itself. It's like bringing your personal computer experience to your mobile device — easily managing huge collections of files and folders will make you forget you don't have your laptop around. -= Connecting =- Dropbox, OneDrive, Google Drive, Box.com, WebDAV, SMB, FTP, SFTP — these are all accessible from inside GoodReader. Download, upload, and sync individual files or huge folder collections. -= Security =- With GoodReader, your data security steps up to the level previously only dreamt of. With Pro Pack®, our new set of professional-level super-features, you'll get AES-256, a military-grade encryption, for all your data, at a price of a cup of coffee! And it's completely independent from the built-in Apple's Data Protection, so even if a hacker steals and unlocks your device, your data will still be protected by another strong layer of security, our own. -= Multi-Windows =- Seamlessly view and manage multiple files simultaneously on iPad. -= Notes =- Capture ideas and comments while reading or studying a technical document without even leaving the app. Sort and group your notes into categories. (Note: Some features require a Pro Pack® subscription.)

ASAP STAR systems provide instantaneous, accurate, and reliable takeoff/landing performance (runway analysis) and weight & balance data. With airport data and surveillance for over 20,000 runways worldwide, STAR's airport database offers analysis in even the most remote locations. Automated monthly data updates ensure that the system is always using the current data. The Flight Management screen serves as the central hub for the STAR systems. From here, the operator begins a flight by entering vital flight information, such as flight number, aircraft, flight date, and departure, arrival, and alternate airports. The operator can then move on to the dedicated Weight & Balance or Runway Analysis screens to enter the respective information and perform calculations. All of the critical results will be transferred back to the Flight Management screen, giving the operator a "snap shot" of all the necessary information needed to takeoff. The STAR systems will take the guess work out of critical weight & balance calculations. The intuitive Weight & Balance screen enables the operator to quickly and accurately perform all the necessary calculations and ensures all loading limits are met. Takeoff weight, CG, and trim tab settings are instantly produced with supreme accuracy. On the Runway Analysis screen, the STAR system produces maximum performance weights for actual atmospheric, runway, and aircraft systems conditions. By calculating for only one set of conditions, payload can be maximized without compromising safety. Maximum takeoff weights for different runways can be quickly compared, then the operator can select a specific runway to view other important data like power settings, V-speeds, stabilizer settings, and more. STAR also offers operators the ability to create their own NOTAM shortened runway, a user friendly function that allows for instantaneous, last minute calculations for changes in airport data. This eliminates the rush for obtaining last minute and shortened takeoff/landing performance, associated possible flight delays, and emergency fees. STAR is a pure self-contained solution for takeoff/landing performance. The STAR advantages will be apparent almost immediately. The user will see just how easy the system is to operate and how quickly data is calculated. However, the most important benefit will be seen later on - the cost savings STAR will provide to your operation. A major air cargo operation projected an annual savings of over $2,000,000 just in increased fuel efficiency thanks to the performance optimization that STAR provides.
