I have to admit that at first sight this didn't look like anything more than a regular set of kitchen scales with a few bowls thrown in for good measure (pun fully intended... sorry). Having viewed the vids at YouTube-1 and YouTube-2 and checked prices elsewhere I came to the conclusion that this is quite a good deal (FWIW they're £39.99 at Currys and this is the lowest price they've ever been on Amazon according to camelcamelcamel)

Seller increased price from £6.99 to £8.99 but still a great deal.
Seller increased price from £8.99 to £9.99.

Official blurb:
Perfect Bake Scale and App
Master bakers achieve great results by following each step of a recipe, making sure measurements and timing are accurate. With Perfect Bake you can now achieve the same fantastic results! Simply connect the Smart Scales to your phone or tablet and you're ready to go. The scale and app takes you step-by-step through the whole baking process, producing delicious results every time.

Easy Baking
Perfect Bake makes hard-to-follow recipes a thing of the past. The included app guides you through the whole process: preparing, adding ingredients, mixing, portioning and baking. You don't even have to measure the ingredients! Just place one of the included bowls on the smart scale and start adding ingredients. The virtual bowl on your tablet/smartphone screen will start to fill up and shows you exactly when to stop. The Perfect Bake app then advances to the next step, showing you what to do. By measuring everything by weight, just like pastry chefs, Perfect Bake gives you masterfully consistent results every time.

Perfect Bake Does the Maths
Want to make more cookies than the recipe suggests? Using a larger cake tin? Have fewer eggs than you thought? No problem. The Perfect Bake App does all the calculations for you to scale your recipe to the amount you want to make. You can select the exact number of cookies, cupcakes etc. you want to make and the recipe will be automatically scaled for you. The same goes for the size of the pan you are using and the amount of ingredients you have to hand. Just select the "scale recipe" option, select the criteria and let Perfect Bake do the rest.

Hundreds of Recipes
Perfect Bake comes with hundreds of recipes that are created (and taste-tested!) by their professional pastry chefs. When the app is updated, new recipes are added to the collection. The recipe database includes gluten-free and vegan options, letting you cater to any need. There is also the option to add your own recipes, either by creating a whole new one or editing an existing recipe. You can add your own photos too.

Three Timers
The Perfect Bake app features three different timers for mixing, baking and cooling. They can run concurrently so that you can streamline your baking process; letting you bake a new batch while the old batch cools. The Mix timer tells you what speed to set your mixer at, what attachment to use and how long to mix for. The Bake timer alerts you when it's time to take your baked goodies from the oven. It even lets you know if and when you should rotate your baking sheet. The Cool timer alerts you when your treats have properly cooled so you can dig in!

Little Details to Help Baking
If you suddenly feel the need to bake, you can tell the app what ingredients you have on hand and it will tell you which recipes you can make. If you pull up one of those recipes there will be check marks next to the ingredients you have so you know if you need to borrow an egg from next door! The app also helps you with portioning. Place the cupcake pan on the scale, pour the batter and the portion meter shows you when to stop. The app also tells you which of the three colour-coded bowls to use for each step. The bowls have non-skid bottoms and are microwave and dishwasher safe, making both the baking and cleaning up process even easier. With Perfect Bake, baking has never been easier. It's easy, fool proof and perfect every time.
