Frequently asked questions
Why can I only have 3 tasks?
Research shows your brain can hold 3–4 items in working memory at a time. Only3 is built around this constraint. To add a new task, complete or remove an existing one first.
What happens if I don’t complete a task in 24 hours?
Tasks auto-archive after 24 hours if not completed. This keeps your list fresh and prevents tasks from lingering forever. Your streak resets when a task expires.
How do streaks work?
Complete at least one task per day to maintain your streak. Miss a day or let a task expire and it resets to zero. Your longest streak is tracked separately so you always have a record to beat.
How much does Only3 cost?
$3/month or $30/year (save $6). Every account starts with a 30-day free trial, no credit card required. See our pricing page for details.
How do I cancel my subscription?
Go to Settings → Subscription in the app and tap “Cancel subscription.” You’ll keep access until the end of your current billing period. You can also email us and we’ll handle it.
Can I use Only3 on multiple devices?
Yes. Only3 syncs across all your devices. Use the iOS app and the web app at only3.dev with the same account.
How do I delete my account?
Go to Settings → Account in the app and tap “Delete Account.” This permanently deletes your account, all tasks, history, and cancels any active subscription. You can also email support@only3.dev and we’ll handle it for you.
