Overdue

Overdue is a minimalist to-do list built around one question: When will you do it? Most to-do apps help you collect tasks. Overdue helps you decide when you will actually do them. A PLAN IS NOT A DEADLINE Every task carries two things: the day you plan to do it, and the day it is actually due. Keeping them apart is what makes a list honest. You can move a plan without pretending the deadline moved with it. ORGANIZED BY WHEN, NOT WHAT No projects, no tags, no priorities. Every task lives on a floor: Today, This Week, This Month, This Year, Someday, and Past. Swipe up and down to move between them. NOTHING QUIETLY ROTS When a plan slips, Overdue does not bury it under a red badge. It asks. Replan anything that slipped in one tap, or clear a whole backlog in about a minute. THE DAY CAN END Finish what you planned and Today says so. At the end of the week a short reflection counts what you completed, replanned and dropped. No streaks, no scores, just what happened.

ZenFlow is a calm place to plan your day, capture ideas, understand your money, and track your health โ€” redesigned as one flat, uncluttered view instead of a stack of separate cards. YOUR DAY, AT A GLANCE Open the app to a Daily Brief: what needs attention now, your nutrition/BMI/cycle/spending signals, and quick capture for a new event, expense, or note โ€” no digging through tabs. SCAN A MEAL Photograph a plate and get an AI-assisted estimate of calories and macros, ready for you to review and adjust before saving. Track daily targets and recent meals from Home. CALENDAR THAT REMINDS YOU PROPERLY Week and month views, conflict warnings for overlapping or back-to-back events, and reminders that show up as alarm-style Live Activities on your Lock Screen and Dynamic Island (iOS) โ€” countdown, time, and one tap back into the app. Track your menstrual cycle alongside everything else, with period, ovulation, and fertile-window predictions. MONEY MADE CLEAR Log income and expenses with tags and categories, set budgets with rollover, and see spending trends, a map of where you spent, and a subscription tracker that reminds you before renewals hit. Attach a receipt photo to any transaction. NOTES THAT KEEP UP One editor for rich text, freehand sketching, voice memos, and inline photos โ€” not three separate tools. Lock a note with Face ID or a password, import a PDF or Word doc to mark up, and search everything instantly. A WEEKLY REVIEW, FREE Every week, ZenFlow surfaces two wins, one thing that needs attention, and one commitment for the week ahead โ€” worked out entirely on your device, no account or AI call required. ASK ZENFLOW Ask what's on your schedule, how much you've spent this month, or your nutrition today โ€” or ask ZenFlow to add an expense, event, or note for you. Every change is confirmed before it saves, with a short window to undo. DESIGNED TO GET OUT OF YOUR WAY A flat, distraction-free interface in Light and Dark mode, tuned typography, and no card-on-card clutter. Free to use, with an optional Pro upgrade for deeper Reports, unlimited exports, and ad-free use. Health and wellness features are for personal tracking and general informational purposes only. They are not medical advice and do not diagnose, treat, or replace consultation with a qualified healthcare professional. Always consult a doctor about any health or medical concerns. AI-assisted estimates (meal scanning, reflections) are a starting point for you to review, not a guaranteed-accurate reading.
