Tikski

Tikski is an offline-first checklist app. Your lists work on your device first — no account and no internet required. Sync and sharing are optional when you want them. Plan faster and stay in flow with lists, tabs, nested tasks, due dates, notes, and starred favourites. Share lists with partners, family, or friends. Keep private lists locked when you need them. Why Tikski • Offline first — fully usable without an account or network • Local-first speed — your data lives on your device • Optional sync — keep phone, tablet, and desktop in sync when you choose • Shared lists — collaborate with people you trust • Private lists — optional lock protection for sensitive lists • Due-date reminders — local notifications so nothing slips • Overdue badges — see what needs attention at a glance • Export & backup — CSV, Markdown, plain text, or a full JSON backup • Privacy-respecting — no ads, no behavioural tracking SDKs How it works Create a list, add tabs for areas of life or projects, then break work into tasks and subtasks. Tick things off, set due dates, star what matters, and reorder when you need a custom order. Everything stays available offline; queued changes sync automatically when you’re back online. Sharing Share a list with someone who also uses Tikski. Both of you can add, edit, complete, and reorder tasks. Changes appear across devices when sync is on. Privacy & ownership Your on-device database is encrypted. Sync uses HTTPS. You can delete local data or your account from Settings. Tikski does not include advertising or behavioural analytics SDKs. Tikski is free. Learn more at https://tikski.com
