Rocket Tracker vs Chemical memo

Rocket Tracker is an app used to keep track of the rocketeer's collection of model and high-power rockets. It can be used to keep track of a rocket's physical characteristics (height, weight, center of gravity, etc.), what engines it can use, when it has been launched and what engines were used for that launch, and what repairs it may need. In addition, Rocket Tracker keeps a list of all engines used by any of your rockets and will list all of your rockets that can use a given engine. This is especially helpful when you have a couple of engines laying around and want to know which of your rockets could use those engines.

This is an application that allows you to easily take notes during chemistry experiments. When you input a chemical formula, the molecular weight is automatically calculated. You can take pictures of measurement data and experimental methods and paste them into the memo. Since the application can be used offline, it can be used in environments with poor reception, such as an NMR room. When you one time purchase the Premium plan, you’ll gain access to the following features: - iCloud Sync Your cards will sync across other iOS and iPad devices logged into the same account.
