Read full descriptionHide full description
PlanTodo is a shared calendar and life coordination app designed for families, couples, friends, and small teams. It brings scattered schedules, plans, and notes into one clear, easy-to-manage, and synchronized space. Create separate shared spaces for family life, dates, travel planning, work arrangements, or personal schedule management, then invite others to view, edit, and participate whenever needed. Everyone stays up to date, with less repeated communication and fewer missed details. PlanTodo goes beyond daily scheduling. Organize to-do lists, keep notes, store photos, and follow recent additions, updates, comments, and status changes in a unified activity feed. Home Screen widgets display your calendar plans at a glance, making it easy to see days with events, review your monthly schedule, and check upcoming plans without opening the app. Whether you are planning dinners, tracking anniversaries, preparing travel checklists, managing shopping lists, or coordinating children's classes and shared responsibilities, everything feels more natural and efficient. Search, tags, and filters also help you quickly find what you need as your content grows. PlanTodo makes shared time management feel closer to everyday life. It works equally well for people who take personal planning seriously and for those who want to organize life with the people who matter most. With clear calendar views, convenient widgets, flexible collaboration, and complete content management, PlanTodo keeps important moments visible, remembered, and easier to accomplish together.

Description (4000 char max) Archius is an AI assistant built for one thing: getting you a real answer, fast. WHAT MAKES ARCHIUS DIFFERENT - Direct. No "Great question!", no filler, no walls of preamble. You get the answer and you move on. - Honest. When Archius doesn't know something, it says so. It won't make up facts, sources, or citations to sound confident. - Actionable. Ask for an email and you get a sendable card — editable in place, send through your real mail app. Ask for a meeting and you get a calendar event ready to add. Not a wall of text to copy out. - Built for answers, not entertainment. No emoji-heavy enthusiasm, no rambling explanations. For people who want the answer and to move on with their day. PRO FEATURES ($12.99/MONTH) - Web search with cited sources. Toggle the search mode and Archius looks up current information, then answers with the URLs it used. - Deep think mode. Switch to the advanced reasoning model for hard problems — math, planning, multi-step logic. - Image understanding. Attach a screenshot, photo, or diagram and ask about it. - 500 fast messages a day, 50 advanced messages, 25 image-aware messages. FREE TIER - Full access to the actionable email and calendar drafting features. PRIVACY - Your messages are sent to AI providers (DeepSeek and Google) to generate responses, then forgotten. Archius doesn't train models on your data and never sells it. Full policy at https://archius.app/privacy. - Local-first chat history. Conversations live on your device, not on our servers. - Sign in with Apple, Google, or email. Delete your account any time from Settings. Made for people who'd rather get answers than be entertained. — Terms of Use: https://archius.app/terms Privacy Policy: https://archius.app/privacy
