The IRAC Insecticide and Nematicide Mode of Action (MoA) Classifications for your mobile device are easy to use searchable databases which allows you to identify insecticide and nematicide active ingredients and their respective MoA groups without the need for a data connection. It is essential for insecticide resistance management (IRM) to minimise the selection of resistance to any one type of insecticide and this is best carried out by the use of alternations, sequences or rotations of compounds from different MoA groups. The IRAC MoA application allows you search which active ingredients below to which groups and should help you in the selection of treatments for effective IRM.
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 19 screenshots above are IRAC MoA's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: IRAC MoA runs a dark set with one background colour (#34A444) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #74BC84, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
