Мобильный "Сейф" для Управления Коллекциями

Task: Card collectors managed their assets in chaos from Excel spreadsheets and paper records. This led to data loss, inability to quickly assess collection value, and inefficient investment management.

Solution: Vinteno team created a convenient mobile app for Android that became a unified center for collection management. It's not just an accounting system, but a full financial tool that works even without internet. All data is securely stored in the phone, so the app works fast and stable in any situation.

Result: The app successfully solves collection management problems. Now all cards are in one place — no need to search for information in different spreadsheets and records. This saves up to 80% of time on accounting and search. The app automatically calculates total collection value, shows how prices change, and helps understand which deals were profitable. Collectors can make decisions based on real data, not guesses. All purchases and sales are recorded in one place, turning a hobby into a manageable process. The app works completely without internet — this is especially important at tournaments and exhibitions where connection can be unstable.
