twodo vs Arca Archive

twodo is a shared to-do for two. Private by default. Share a task when you both need it. Today is home — your list. Pair with one person using a simple code. Shared tasks show up for both of you. Everything else stays private. • Private by default — you choose what to share • Today as home — your tasks, due or anytime • Pair with a code — one partner • Shared tasks — see theirs, keep yours private unless you share • Remind your partner on a shared task • Ask them to add a shared task • Unpair or delete your account anytime twodo is free. Built for iOS. We never sell your data.

Arca is your EU paper archive you can ask with Claude, ChatGPT, or another AI. Every document starts private: an assistant only sees it if you grant access. Revoking in the app cuts access instantly. Photograph an invoice or contract: it is filed with a summary, category, place and date — on the phone first, then on servers in the European Union. Arca also works without an assistant.
