Price Truth

## Question 1 - Why do I have to install this App? Let's take a concrete example. There are two milks in the supermark, one is ¥22.8 and 300g, the other one is ¥26.8 and 400g. First impression, the former is cheaper, but which one is more cost-effective? After calculating with the "Price Truth" App, the former is ¥38/kg, and the latter is ¥33.5/kg. Of course, the latter is more cost-effective, but without Price Truth App, most people can not know the truth. The mission of "Price Truth" is helping everyone choose the most cost-effective products as soon as possible. ## Question 2 - Who needs this app? If you are not so sensitive to the brand and are very sensitive to the price, you should try to choose the most suitable price/performance ratio. You like to buy food in the supermarket, then you should install this app right away, save you money every day! Don't worry if you are old enough to use this app. For the convenience of everyone, all the buttons are big and convenient for everyone to see. ## Question 3 - When do I need to use this app? When you are facing the shelves, the products in front of you are all of the same kind. Buying anyone can meet your requirements, but you expect to buy a relatively cheap one. But the actual situation is different weight/volume units and different prices, you cannot find witch is cheaper in a few minutes. At this time, you need to open the "Price Truth" App, enter the weight and price of several products, and it will be very clear which product is cheaper. ## Question 4 - What types of products are more suitable for selection with this app? This App will be very very useful when buying food and drinks, for example, vegetables, fruits, soy products, meat and eggs, seafood, rice and noodles, condiments, instant food, ice cream, water, bear and so on. Also applies to shampoo, conditioner, hand soap, toothpaste, laundry detergent, and bleach. What they have in common is that there will be various sizes of packaging, large packaging and small packaging, the measuring unit is either milliliters or gram, the price is also different. Some packaging is small, but the average price will be more expensive than the other large packaging. If you don't compare them, we are always unknown the differences. ## Question 5 - Where do I need this app? The most useful place is the supermarkets. Similar to Wal-Mart, there are many kinds of goods. All the goods are clearly marked. It is the main battlefield of this app. Of course, the online supermarket, just like Taobao is also a good usage. Convenience store is not OK, because categories is very few, or the price is not clearly marked.
