The "年賀状アプリ コンビニで年賀状2023" app by CONNECTIT Inc. is the perfect New Year's card-making solution for those who want to create and print their own cards from their smartphones and get them printed at a convenience store. With over 460 design templates available, the app lets users choose from a wide variety of stylish designs, including photo frame types popular with moms and classic illustration types. Users can easily create a card by selecting a template, inserting a photo from their smartphone's camera roll (only for photo frame type designs), editing the design with messages and stamps, and then getting a reservation number to print the card at a nearby Seven-Eleven convenience store. The app is free to download and use, and users only need to pay for the printing cost and the New Year's cards themselves.
