Manage Your Sports Card Collection
CardsMaster is available on the Apple App Store!
What CardsMaster Does
Organize and explore your sports card collection with ease. The app supports baseball, basketball, hockey, American football, and European football (soccer) cards, each with its own dedicated space, so every sport stays clearly separated and easy to manage. Switching between sports is fast and effortless.
For every card, you can store both front and back images, along with a wide range of custom details and notes. Whether you’re a casual collector or more detail-oriented, all important information is always close at hand.
Need a better way to review your collection? Create A4-sized PDF files with enlarged card images for comfortable viewing or archiving. Perfect for browsing your cards on a bigger screen or keeping offline records.
You can also assign custom statuses to both cards and the players featured on them, helping you track condition, availability, importance, or any system that fits your collecting style.
100% local storage. All card data and images are stored entirely on your device. Nothing is uploaded, synced, or stored externally — your collection stays fully private and always under your control.
Card-level Customization
Personalize each card’s appearance in detail — from font colors and visual themes to the tools shown on the card. Customization is applied per card, so every card can look and function exactly the way you want.
Simple to use, flexible, and built for modern collectors — this app makes managing sports cards clear, visual, and effortless.
Your data, your choice You can store as much or as little information as you like for each card — from just front and back images to extensive custom details. The app does not automatically fetch or generate any data; everything is added by you.
That said, a lot of care has gone into the app’s design to make entering and managing data as smooth and effortless as possible, even when working with larger collections.
Other Features
More data, more value. The more information you add to your cards, the more useful the app becomes. For example, when you enter a player’s date of birth, the app automatically shows the player’s age in years, months, and days, giving you instant, meaningful insights from your data.
Bring your cards to life with Pull Rate. Pull Rate shows which cards you naturally come back to the most. By tracking how often you view each card, the app highlights the cards that matter most to you. You can easily see which cards have been your most viewed and “hottest” during a selected time period, such as the last month or the past year — turning everyday browsing into meaningful insight.
CSV import & export. You can export and import your card data using CSV files, making it easy to move most of your collection data to an external spreadsheet or bring it back into the app. This allows flexible editing and bulk management of information. The CSV transfer includes most card data, but images are not included and remain stored locally on your device.
Built with care — and constantly improving. The app is actively developed and updated regularly with improvements and new features. We genuinely value user feedback and use it to guide future updates and refinements. If you have ideas, suggestions, or feature requests, we’re always happy to hear from you — this app is built together with its users.
Independent and brand-neutral. This app is not affiliated with any sports league, team, player, or card manufacturer. It is an independent, brand-neutral tool designed solely to help you manage and enjoy your own card collection.
