トイトレ is a free iPhone app developed by Unicharm Corporation in the Lifestyle category. This app is designed to encourage parent-child communication and help children develop an interest in using the toilet.

Based on developmental psychology, the app offers interactive features that make toilet training enjoyable for both parents and children. By scanning a special sticker sheet with the app, a 3D character named "ムーニーちゃん" appears on the screen. Parents can use this character to encourage their children to use the toilet. The app also allows parents to take photos of their child sitting on the toilet, which can be customized with crowns and stars to boost their confidence and motivation.

In addition, the app includes features such as toilet records and reminder notifications, allowing parents to track their child's progress and adjust the training accordingly. The app also offers rewards in the form of cards, stamps, and frames, which keeps children engaged and motivated throughout the training process.

With its positive and interactive approach to toilet training, トイトレ aims to create a positive and enjoyable experience for both parents and children. It is a valuable tool for parents looking to support their child's development and build a strong bond through toilet training.
