Brewguide is the companion App for the Acaia Pearl S Welcome to your new scale! The Acaia Pearl S pairs with all of our apps but this is the one to use to set up the scale. If you don’t have a Pearl S, you can still browse and create recipes. In Brewguide, you can: * Walk through a setup guide to adjust settings like turning on/off modes, changing the weight unit, adjusting the auto-off timer, turning on/off the button sound, and changing the temperature unit. * Personalize your Pearl S with your own loading message * Browse official recipes or create and share your own with a QR code or link * Easily transfer a recipe to your Pearl S - the scale holds one recipe at a time To enter Brewguide mode, where you view the loaded recipe’s prompted steps, hold the Tare button until you see “Brewguide” on the scale.
GrindBook

GrindBook is an app for remembering the coffee you bought, and reminding you which ones to buy again and which ones to avoid. Do you want to take detailed notes about brew temperature and duration? Do you want to log every cup? Then GrindBook is not for you. GrindBook is not about perfecting your coffee consumption or joining the Quantified Self. GrindBook is for remembering your beans. That is all. It tries to do its thing and get out of your way, and out of your mind. GrindBook thinks coffee should be enjoyed, and takes coffee seriously enough not to optimize it. GrindBook does not want your data. What is on your device stays on your device. Syncing, if enabled, happens through the Apple account already on your device. You can always export your data as Markdown files, so your beans are free to go elsewhere. GrindBook is a simple app. GrindBook is free. You can leave a tip if you enjoy the app and want to help keep the developer fully caffeinated. Tips do not unlock any features or new functionality. You will get a thank-you note though.

Verdict
The clearest difference is in-app purchases: Brewguide at none against GrindBook's 3. Brewguide also leads on iOS requirement (14.0 vs 18.0). On price, update cadence, ads and device support there is nothing between them.
