I've written about the Mix Tank app  before, and now they've released an update. If you haven't already downloaded the app, do it now. It's an easy-to-use tool for spray management and chemical applications.
A new app feature, available for iPhone and Android, is Mix Sheets. Using that feature, you can capture product use rates, field size, spray volume and tank size and receive the rate per acre, load and field. The once documented, the Mix Sheet can be emailed.
Other features of the app include a mix guide, spray logs, mixing precautions and social media sharing options. There's also a weather integration feature, which can be purchased within the app.
The overall app has a simpler design, too, offering easy access to the menu at any time using a simple swipe.
So, with all these features, I think you should download the app and give it a try. And once you've used it, I'd like to know what you think of it. Comment here or send me a message and let me know: is it easy to use, does it offer the tank-mixing features you need? What would you change about the app?
