TENGO is a free productivity game — a bingo card for the ten-minute tasks cluttering your brain. Fill your card, complete a line, and feel good.
I built TENGO because I realized many of the tasks I kept putting off took minutes. Not hours. Not days. Reply to that text. Schedule the appointment. Break down the cardboard boxes. The kind of tasks that sit in your head and quietly drain your energy all day.
The problem with most productivity apps is that they incentivize planning vs. actually doing. I didn't need another to-do list app. I needed a reason to start.
"Ten minutes. That's it. Anyone can do anything for ten minutes."
So I built a productivity game. A simple bingo card. You add your tasks — or let the AI break down a bigger goal into bite-sized pieces — and try to complete a line. The satisfaction of marking a square is completely disproportionate to the effort involved. That's the whole point.
TENGO is free, works on any device, requires no account, and stores everything on your own device. No ads, no tracking of your tasks, no upsell. Just you and your card.
FAQs
Is TENGO really free?
Yes, completely. No account required, no premium tier, no ads. If it helps you and you want to support it, there's a Buy Me a Coffee link — but it's entirely optional.
Where does my data go?
Nowhere. Your tasks and progress are stored on your own device using browser storage. We don't have a database. We can't see your tasks. They're yours.
What happens at the end of the day?
Your card resets at midnight Pacific time each day — a fresh start. Any tasks you didn't complete carry forward automatically so nothing gets lost.
What's the "shared card"?
Every day, TENGO generates the same 24 tasks for everyone — drawn from a curated list of common ten-minute tasks. Everyone playing on the same day gets the same card, so you can compare progress with friends.
Can I share my progress?
Yes! Hit the share button on your card to copy a snapshot of your progress — which squares you've completed and how many lines you've got. Great for sending to a friend or posting on social. The daily shared card makes comparing results especially fun.
Why ten minutes?
Because almost anything feels possible if you tell yourself it'll only take ten minutes. And it usually does. Ten minutes is small enough to start, big enough to matter.
Can I use it offline?
Almost entirely, yes. The only feature that needs an internet connection is AI task generation. Everything else — your card, your marks, your progress — is stored locally on your device.
Who made this?
TENGO was built by someone who is, clinically, occasionally overwhelmed — with a lot of help from Claude (Anthropic's AI). It started as a personal tool and became something worth sharing.
Can I share feedback or request a feature?
Please do — we'd love to hear from you. Reach out at for feature requests, bug reports, or just to say hi.
