Unified Planner is the aggregation layer above my application ecosystem: it collects data from TightWallet, SubManager, AutoMotoKeeper, Home Managed, and Calendar Events and presents them in a single, coherent calendar. The interesting logic is deduplication: the same commitment can come from different sources, and the planner ensures it appears only once, with the correct source. The result is a complete overview of deadlines, renewals, and events, without having to open five different apps. Access is protected via Google login and reserved for the authorized user.
