BIFF - Planner

BIFF is a paid subscription app. A BIFF Plus auto-renewable subscription is required to use the planner after sign-in and onboarding. All core features shown in this listing, including planning, task tracking, receipts, behavior-aware recommendations, and weekly stats, require BIFF Plus. BIFF is a behavior-aware planner with receipts. It tracks the gap between what you planned and what you actually did, then adapts future scheduling around your real patterns. The live scoring path stays deterministic and inspectable, so recommendations can explain themselves instead of feeling random. BIFF is not a generic calendar. It notices overloaded days, fake morning plans, repeat misses, and the slots you keep ignoring. It keeps score, surfaces the pattern, and lets you edit everything manually. BIFF Plus paid subscription features include: • manual tasks, recurring tasks, and work schedule setup • task instances with done, snooze, skip, and reschedule tracking • planner and receipts views with behavior-aware recommendations • explanation text and score breakdowns for optimizer moves • weekly recap and behavior stats built from actual task history BIFF does not use an LLM in the live scheduling loop. Scheduling remains deterministic. Future model work is still shadow-only, and the current product logic is heuristic-first and fully explainable.
