I currently don’t have the time or resources to maintain Rocket Calculator. It will remain on the app store for those who have purchased it, but I don’t plan to continue updating the software. Thank you all who have purchased and used this product.
I have decided to open-source the code base of the most recent version. The address is https://bitbucket.org/peter_stanley/rocket-calculator-public
The current version in the app store is free for as long as it remains there. I will not renew my Apple developer account, which should expire in April/May 2017. After that it’ll probably be pulled, but those who’ve purchased will still be able to download it after that.
This version of Rocket Calculator includes the missing Aerotech single use D21 and E15 motors. I also added the air frame dimensions for Aerotech, PML, Always Ready Rocketry(Blue Tube) and Madcow body tubes. Lately the Apple review time has been abysmal, but hopefully it will be out in 5 to 10 days.
This updates contains some corrections to motor data. I also changed the minimum required iOS version to 6.1.
If you’re a current or potential user of Rocket Calculator, please take a moment to fill out this brief survey, https://www.surveymonkey.com/s/C72CBDG. I’m working on a new, cross-platform version, and need your input. Thank you for your time.
Version 1.5 update is available. Motors are managed better internally. The app now uses data compiled by Dave Walden, available on Rocketry Forum. The Quest motor data was compiled separately from the NAR website. The motor model number is now displayed on the Altitude Prediction screen.
I’ve started working on a cross-platform version that will run on iOS and Android devices. I’m still on track with having that available by end of summer. I’ll post updates on the status.
This actually came out last week, but version 1.4 is available. It contains some minor motor updates and includes the newest versions of the NAR Model Rocket and High Power Rocket Safety codes (Available in the Info->quick reference section).
I intend to release a more comprehensive motor update within the next month, to include all the newer Cesaroni and Aerotech motors. I’m also planning the development of a cross-platform version that will run on iOS and Android devices. I’m hoping to have this by end-of-summer.
The update is available in the App Store.
For your reference, instructional videos for using the app are available here.
