How it works

Thirty seconds a day. That’s the whole habit.

  1. Log a tiny flex

    Drank water before coffee. Did ten press-ups. Finally replied to that email. It all counts.

  2. Your coach reacts

    A punchline written for exactly what you did, in your coach’s voice. Never a generic “great job”.

  3. Tomorrow’s challenge

    One step slightly bigger than today. Accept it, and your coach asks how it went tomorrow.

Did 10 press-ups before work
Ten. Calm down, Olympics. Eleven tomorrow.
Sarcastic mate
Tomorrow11 press-ups, before the kettle boils.

Same flex, five very different reactions. Switch any day. Here’s what each one says to “Did 10 press-ups before work”.

Hype friend: a yellow blob in a party hat with pompoms. Be nice

“Ten press-ups before work! Your arms are telling all their friends.”

Bestie: a pink blob in sunglasses with an iced coffee, winking. Be real

“Babe. Press-ups BEFORE work? Who are you. Text me tomorrow.”

Sarcastic mate: a blue blob in a beanie with a mug of tea and a smirk. I can take it

Sarcastic mate

“Ten. Calm down, Olympics. Eleven tomorrow.”

Drill sergeant: a green blob in a ranger hat, saluting and blowing a whistle. Push me

Drill sergeant

“TEN, soldier? Acceptable. Tomorrow I want TWELVE. Dismissed.”

PLUS Little Devil: a red blob with horns and a golden trident, winking. Roast me

Little Devil

“Ten press-ups. Your sofa has filed a complaint.”

Gentle mode: a lavender blob wrapped in a blanket with a cup of tea.

Questions

Good questions, short answers.

Is Tiny Flex free?

Yes. The free version has four coaches, personal replies, daily challenges, the journal, share cards and a widget. Plus adds the Little Devil, sharper comebacks, full widgets and the Dynamic Island.

When does it launch?

On iPhone in December 2026. Android comes later.

Is it on Android?

Not yet. Tiny Flex is on iPhone now, and Android comes later.

What happens to what I write?

Your flexes are saved on your phone. To write a reply, the flex you type (and a few recent ones, so your coach can call back to them) is sent to Anthropic, the company that helps write the replies. There’s no account, so we don’t know your name or email. Prefer it stays on your phone? Switch to ready-made lines any time.

Is the Little Devil actually mean?

He’s savage about the size of your win, never about you. No jokes about bodies, looks, money, health or anything personal. He’s opt-in, and there’s a “Too far?” button if he overdoes it.

What if I’m having a rough day?

Write it anyway. When it sounds like a hard day, Gentle mode takes over: no jokes, just a kind word. Showing up counts.

How do I cancel Plus?

In your iPhone’s Settings, tap your name, then Subscriptions. Cancel at least 24 hours before it renews and you won’t be charged again.

Your first tiny flex starts here.

See you in December.
