Writing Board - Whiteboard App 对比 My Valuable Stamp Collection 的使用情况和统计数据

Have you checked the value of your stamp collection lately? With our stamp collecting app, you can keep track of all the stamps you've collected, their value, and any other details you'd like to add. Our app lets you sort your stamps by denomination, year, quantity, and value. You can also group stamps by year, country, and denomination for easy reference. To view a stamp in detail, simply double-tap the image or use the zoom button on the top navigation bar. You can enlarge or shrink the image using two fingers, or move the image around with one finger. Before entering a stamp, browse through the reference lists for centered stamps, condition, countries, faults, grade, gum, margins, paper, perforations, series, and status. You can add or remove any of these reference lists as needed. Take a look at the attached screen shots from the My Stamps Collection app for iPhone and iPad. If you have any comments, suggestions, bug reports, or requests for this app, please send us an email. We'd love to hear from you!
