SmartLaunch is a rocket launch simulation app that gives on-the-spot information about the initial moments of a planned launch. Specifically, given a few details about the rocket and the motor, it will give the speed at which the rocket will leave the launch guide, the angle of attack of the rocket with any crosswind, as well as the thrust-weight ratio based on the initial thrust of the motor (not the average thrust). Using this information, the rocketeer can judge whether a specified motor may result in a stable flight under the given conditions. The app also gives the expected apogee altitude and coast time for the proposed flight. Version 1 features:
 User specified units (metric, standard) Set launch angle by tilting the device, either up against launch guide or by camera view Set launch site altitude by GPS (if available and Location Services allowed) Database of over 800 commercial rocket motor thrust curves Remembers multiple rockets and easily switches back and forth User can decide which motors they want to see in the list - by diameter, impulse class or manufacturer ## Key features - On-the-spot launch information - Speed and angle of attack calculation - Thrust-weight ratio analysis - Expected apogee altitude - Coast time estimation - User-specified units - Device tilt for launch angle ## Recent user reviews (10 of 13) All indexed reviews: https://appshunter.io/ios/app/smartlaunch-2/id568729036/reviews.md ### 5/5 — Simple, easy to use, accurate *2019-05-19, version 2.31* The title says it all. The simulations match what other simulation software and apps compute, so it’s as accurate as one could expect. Thanks for developing a great tool for the masses! The version on the App Store says 2.31, but the app says it’s 2.30. Can someone tell if I’ve got the latest version and it’s just a bug? ### 4/5 — Great app just one gripe with it *2019-01-18, version 2.31* I love this app and is fairly accurate to what I’ve experienced with my launches. However I don’t have an altimeter to measure actual heights so the Cd value is likely off a bit. My only gripe with the app is the lack of certain rocket motors, namely the f15’s from estes that I use regularly. I’ve put in a f26 as a placeholder but would like to see a preprogrammed f15 or an option to put in your own engine parameters ### 4/5 — Smart app *2017-08-05, version 2.31* Very impressed with the physics programmed into this tool. Gave it a 4 out of 5 because an F-15 Estes engine was not listed. ### 5/5 — Great app *2015-01-19, version 2.14* Great app to validate parameters for launch. ### 1/5 — Won't work! *2014-11-09, version 2.12* Can't change motor or get preloaded kits to select and save ### 5/5 — Good rocket app *2014-09-07, version 2.12* Nice app. It has a nice selection of engines and manufactures. Let's you program several variables into the launch scenario. While not overly deep it is nice for a rough guess of how high your rocket go given some variables ### 4/5 — Great app for rocketeers *2014-05-19, version 2.11* This app is very helpful when you want to get a rough idea of how your rocket will perform with a variety of motors and launch conditions. My only complaint is that it has a ton of motors pre- programmed, but falls short in the number of common rocket kits that are manufactured. If it had a bigger selection of rocket kits/manufacturers, it would get the final start from me and be a 5-star app. ### 4/5 — Very Good Portable Rocket Predictions *2013-10-20, version 2.0.2* This is a great program for quickly getting an idea of what a given rocket weight/diameter/cd and motor combination will yield, regarding apogee altitude, speeds, etc. I can do single engines, as well as clustered engines. It does not do multi-stage, however ( I sure wish it would!). Also, there is no descent/parachute calculation. Once your rocket has flown, you can enter the altitude and engine it flew to/with, and it will calculate and new Cd. If you then save this Cd, it will be used in all further calculations for other motors you might try. This application is great for standing in the rocket vendor's trailer on launch day and determining the flight characteristics of the available motors the vendor has for sale. It's not as full-featured as RockSim, but you probably aren't going to be designing a rocket on launch day, are you? 4 Stars as is, but would be 5 Stars with staging predictions. ### 5/5 — Indispensable *2013-09-11, version 2.0.1* Great software for learning rocketry. ### 5/5 — Very nice! *2013-05-17, version 2.0.1* A very useful tool! Very intuitive to use. I really like being able to set the motor preferences. ## Frequently asked questions about SmartLaunch 2 ### What kind of information does SmartLaunch 2 provide for rocket launches? SmartLaunch 2 provides on-the-spot information including launch speed, angle of attack with crosswind, thrust-weight ratio, expected apogee altitude, and coast time. This helps users assess motor stability for a given flight. ### Can I customize units in SmartLaunch 2? Yes, SmartLaunch 2 allows users to specify their preferred units, supporting both metric and standard measurements. This ensures flexibility for users worldwide. ### How does SmartLaunch 2 determine the launch angle? You can set the launch angle in SmartLaunch 2 by tilting your device. This can be done either against the launch guide or by using the camera view for more precise aiming. ### Does SmartLaunch 2 use GPS for launch site altitude? SmartLaunch 2 can utilize GPS to set the launch site altitude if available and Location Services are allowed. This adds another layer of accuracy to the simulation. ### How extensive is the motor database in SmartLaunch 2? SmartLaunch 2 features a database of over 800 commercial rocket motor thrust curves. Users can also filter this database by diameter, impulse class, or manufacturer. ### What is the price of SmartLaunch 2? SmartLaunch 2 is available for a one-time purchase of $0.99. This provides full access to all simulation features without ongoing costs. ### What devices is SmartLaunch 2 compatible with? SmartLaunch 2 is compatible with iPhone, iPad, and iPod devices. It is designed to run on Apple's mobile operating system. ### How often is SmartLaunch 2 updated? The latest version of SmartLaunch 2 is 2.31, which was last updated on April 11, 2017. While not frequently updated recently, it offers a stable set of features. ## Version history (last 1 release) ### 2.31 — 2017-04-11 This app has been updated by Apple to display the Apple Watch app icon. Fixed a little interface glitch. Working on a major interface update for all size devices soon. Added the latest updates I have for commercial motors. If you do not find the motor you are looking for please drop me a line and I will see what I can do. ## Apps similar to SmartLaunch 2 | App | Rating | Price | Category | | --- | --- | --- | --- | | [LIVVE](https://appshunter.io/ios/app/livve/id1322452200) | — | Free | Entertainment | | [Emotes For Fortnite Dances](https://appshunter.io/ios/app/emotes-for-fortnite-dances/id1386334220) | 4.7 (2,112) | Free | Entertainment | | [Mine Maps for Minecraft PE](https://appshunter.io/ios/app/mine-maps-for-minecraft-pe/id1645671020) | 2.0 (4) | Free | Entertainment | | [Drop Guide For Battle Royale](https://appshunter.io/ios/app/drop-guide-for-battle-royale/id1450395700) | — | Free | Entertainment | | [FTV - Movie & TV Show Manager](https://appshunter.io/ios/app/ftv-movie-and-tv-show-manager/id1462164060) | 3.5 (12) | Free | Entertainment | | [Catholic Misal](https://appshunter.io/ios/app/catholic-misal/id1604122400) | 4.2 (50) | Free | Entertainment | ## More apps by GetSmart Software - [Smart Barcodes](https://appshunter.io/ios/app/smart-barcodes/id1302979989) All apps by GetSmart Software: https://appshunter.io/developer/564563189 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
