About this app

very morning, one app idea worth building — with the thinking already done.

Not a list. Not a feed you scroll. One idea a day, in the categories you pick,
delivered like a briefing.

WHAT YOU ACTUALLY GET

Each idea arrives as a full brief, not a one-line prompt:

• The pitch — what it is, in a sentence you could say out loud
• Target user, problem, solution — who it's for and why they'd care
• Monetization and revenue streams, with rough numbers
• Market, acquisition, retention — how it would find and keep users
• Competitors and the honest risks
• Tech stack, MVP scope, effort estimate
• Key features and screen-by-screen breakdown

It's the work you'd normally do in an afternoon before deciding whether an idea
is worth a weekend.

BUILT FOR PEOPLE WHO ACTUALLY SHIP

Every brief has a Copy prompt button. One tap puts the whole thing on your
clipboard, wrapped as a build instruction — ready to paste straight into Claude
Code, Cursor, Codex or whatever you build with. From idea to first commit
without retyping a thing.

TEN CATEGORIES

Productivity · Health & Fitness · Mental Wellness · Education · Finance ·
Games · Social · E-commerce · SaaS & B2B Tools · AI Utilities

Follow the ones you care about. Change them whenever you like.

YOUR ARCHIVE GROWS

Every idea you've been given stays yours. Browse the full library, filter by
category, save the ones worth returning to. The good idea you weren't ready for
in March is still there in September.

A DAILY NUDGE, IF YOU WANT ONE

Set a reminder for the time you actually think — 7am with coffee, or 9pm when
the house is quiet. Or turn it off entirely.

NO ACCOUNT. NO TRACKING. NO ADS.

There's no sign-up, because there's nothing to sign up for. No email, no
password, no social login. We don't collect your name, contacts, location or
advertising ID. There are no analytics SDKs and no third-party trackers in the
app. We're not in the data business — we're in the one-good-idea-a-day
business.

PLANS — 3 DAYS FREE

Both plans start with a 3-day free trial if you haven't subscribed before.

• Monthly — one idea a day, from one of your chosen categories
• Yearly — one idea a day for EVERY category you follow, and cheaper per month

Your trial converts to a paid subscription automatically unless you cancel
before it ends. Cancel any time in Google Play — during the trial and you're
never charged. If you cancel later, every idea already unlocked stays in your
library; you just stop receiving new ones.
One app idea every morning, business case included.
