One of my favorite iOS kitchen utilities, AeroPress Timer ($4.99 US), has updated to version 3 with a complete rebuild and new functionality.
AeroPress Timer is an iPhone app that steps you through the stages of coffee making with an Aerobie AeroPress. Each step, Pour, Stir, Steep, and Plunge, has its own countdown timer. Once you get into the world of AeroPress, there are a hundred different variations and precise recipes for making different types of coffee, so it's a handy guide.
The app has always had a great selection of AeroPress recipes, but the biggest, baddest new feature: you can now create and add your own recipes. You can also favorite recipes, add notes, and there's a new visual grind size guide accessible from any recipe.
This update did lose Apple Watch functionality, which is a bummer, but the developer plan to have it back soon.
AeroPress Timer is available on the App Store.
