App Idea Validator

How the app idea validator works

Great software rarely fails because of the code, it fails because the idea underneath it was never sound. This validator scores an app or software idea across the six dimensions that product teams and investors weigh again and again: how severe the problem is, how big the market is, how differentiated your approach is, whether people will pay, whether there's a gap in the competition, and how well you fit the market.

You rate each dimension Weak, OK or Strong, worth 1, 2 or 3 points. The six ratings are summed (6 to 18) and rescaled to a clean score out of 100. Equal weighting keeps it honest: a brilliant market can't paper over a problem nobody feels, and deep expertise can't rescue an idea no one will pay for.

score = round( (sum of 6 ratings ÷ 18) × 100 )
75+ worth building · 50-74 refine first · under 50 rethink

Once the idea holds up, the next questions are cost and scope. Estimate the build with the software development cost calculator, or decide whether to build at all with the build vs buy calculator. When you're ready to talk specifics, see our services.

App idea validator, FAQs

What score means my app idea is worth building?

75 and above signals strong fundamentals across all six dimensions, the idea is worth validating with real customer conversations and then building. 50 to 74 means there's genuine merit but at least one dimension needs strengthening first. Below 50 usually points to a fundamental gap, most often a weak problem or unclear willingness to pay.

Which dimension matters most when validating a software idea?

Problem severity and willingness to pay do the heaviest lifting. A hair-on-fire problem people already pay to solve survives a mediocre market or crowded field, whereas a large market means nothing if the pain is a mild nice-to-have. This tool weights all six equally so a single weak link is easy to spot.

Is this a real market study?

No, it's a fast, directional gut-check built entirely from your own honest ratings, not external data. Use it to surface the weakest part of your idea before you spend money. Confirm the real answer with customer interviews, a simple landing-page demand test, and a scoped build estimate.
