BIFF - Planner

BIFF is a behavior-aware planner with receipts. The free plan lets you schedule up to 5 task blocks per day. BIFF Plus is an auto-renewable subscription that unlocks unlimited daily task blocks when five is not enough. BIFF 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. Free BIFF includes: • planning up to 5 task blocks per day • 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 Plus includes: • unlimited daily task blocks • Apple-managed purchase, cancellation, and restore 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.
