Subscriptions, user accounts, database, admin panel — standard patterns we've shipped many times. Whether it's a bill splitter, booking platform, membership app, quote generator or B2B dashboard: once the core flow is clear, four to eight weeks typically gets you something real users can test. Mr. Splitter is a product we built this way ourselves — subscriptions, auth, LINE LIFF, shipping and iterating ever since.
