The App Idea Checklist: 12 Questions Before You Build

Before writing a single line of code, answer these 12 questions to know if your app idea is worth pursuing — or a trap that will waste months of your life.

Before writing a single line of code, answer these 12 questions honestly. If you can't answer them, you're not ready to build — you're ready to research.

1
Market

Are people actively searching for a solution to this problem?

Green light

Yes — search volume is measurable and trending up. Reddit threads, Facebook groups, or App Store reviews prove the frustration exists.

Red flag

The only people who understand the problem are you and your developer friends.

2
Market

Does at least one competitor have 10,000+ downloads or paying customers?

Green light

Yes — this confirms the market exists and someone is already paying for a solution.

Red flag

No competitors at all. This usually means no market, not a blue ocean.

3
Competition

Have you read at least 20 one-star reviews of your top competitor?

Green light

Yes — you've identified 3+ recurring complaints that represent your differentiation opportunity.

Red flag

You haven't, or the complaints are all nitpicks that don't represent a real gap.

4
Competition

Can you name your unique differentiator in one sentence?

Green light

"We're [X] for [audience] that does [differentiator] unlike [competitor] by [mechanism]."

Red flag

Your differentiator is "cleaner UI" or "better UX" — features, not a moat.

5
Monetization

Are users in this category already paying for competing apps?

Green light

Yes — at least one competitor charges ≥ $4.99/month or has a meaningful paid tier.

Red flag

The whole category is free with no subscription precedent. Charging is unproven.

6
Monetization

Have you validated a pricing model (subscription, IAP, or one-time)?

Green light

Subscription is the validated default for apps with ongoing value. Cross-checked with competitor pricing.

Red flag

Planning to monetize with ads with no fallback. Ad revenue per user is typically $0.01–0.05/month.

7
Feasibility

Can you ship an MVP in 4–8 weeks that tests the core hypothesis?

Green light

Yes — the MVP is one screen or one key flow, not a full-featured app.

Red flag

"We need 6 months for the MVP" — a 6-month MVP is a funded product, not a validation tool.

8
Feasibility

Are there any App Store guideline or platform risks?

Green light

App falls clearly within guidelines. No dependency on APIs that Apple/Google restrict.

Red flag

The app requires access to contacts, health data, or financial info — extra review scrutiny.

9
Platform

Does the platform (iOS/Android/Web) match where your users actually are?

Green light

Consumer habit app → iOS first. Android market share in your target geography supports the platform.

Red flag

Building iOS because you have a Mac, not because your target audience uses iPhones.

10
Growth

Do you have a realistic user acquisition channel that's already working for similar apps?

Green light

ASO, community, content, or word-of-mouth has worked in this category. You have a distribution plan.

Red flag

"We'll grow organic." Organic App Store discovery is near zero without an existing audience.

11
Retention

Is there a reason users will open the app more than once a week?

Green light

Core loop creates daily/weekly habit (tracking, streaks, social, scheduling).

Red flag

The app solves a one-time problem with no reason to return — one-shot utility apps have terrible retention.

12
Timing

Is there a macro trend, technology shift, or regulatory change creating a tailwind?

Green light

An AI advancement, platform API, or market shift makes this uniquely possible now.

Red flag

This could have been built 5 years ago and wasn't — ask yourself why.

Scoring key

10–12 green lightsStrong signal. Build the MVP and launch quickly.
7–9 green lightsPromising. Address the red flags before committing.
4–6 green lightsRisky bet. Validate the weakest points first.
Under 4Skip it. The fundamentals aren't there — find a better idea.
