Validate your app idea before you build
Paste your idea and see the real posts where people are already asking for it, complaining about the alternatives, or trying to solve the problem themselves — so you know there's demand before you spend months building.
Get real evidence in minutes
Learners who've outgrown streak-based apps are vocal about the speaking gap and seeking alternatives.
“Streak of 500 days, conversation skills of day 1. Anyone else?”
“I finished my tree but still can't speak, what now?”
Quick answer
An app idea validator tests whether real people want what you're about to build by finding the conversations that prove — or disprove — demand. It's the fastest market research for an app idea: ReachFront surfaces actual posts where people ask for your idea, complain about existing options, or hack together workarounds, then summarizes the signal so you can decide to build, pivot, or drop it before writing any code.
How it works
Validate in three steps
Describe your idea
Write a sentence or two about the app you're thinking of building and the problem it solves. No spec required.
See the evidence
We surface real posts where people ask for it, complain about the alternatives, or describe the pain — the demand signal in their own words.
Decide with confidence
Read the summarized signal — how much demand, how loud the frustration, which features people beg for — and choose to build, sharpen, or pivot.
The basics
Why validate before you build?
The most expensive way to test an app idea is to build it. Months of work, then launch, then silence — because the demand you assumed was there never was. Validation flips that: you look for proof of demand first, cheaply, before committing real time.
The strongest proof isn't a survey where people are polite. It's unprompted, public evidence — someone posting 'is there an app that does X?', a thread of complaints about the tool everyone uses, a workaround people cobble together because nothing good exists. Those are markets asking to be served.
The Idea Validator finds that evidence for you and summarizes it: how many people are asking, how strong the frustration is, and which features they keep requesting. You walk into your build knowing there's a real audience — or you save yourself months by finding out there isn't.
The difference
Validating by asking around vs. with the Idea Validator
| Asking around | With the Idea Validator | |
|---|---|---|
| Signal quality | Friends are kind and surveys are hypothetical, so the feedback is politely biased. | Unprompted public posts where people described the problem with no idea you were listening. |
| Finding evidence | Dig through Reddit and forums yourself hoping to stumble on demand. | Real posts asking for your idea, surfaced and summarized for you. |
| Reading the market | Eyeball a pile of links and guess how strong the demand really is. | A clear read on how much demand there is and how loud the frustration is. |
| Spotting the opening | Miss the specific complaints that reveal where existing apps fall short. | Complaints about the alternatives and repeated feature requests, pulled out for you. |
| Cost of being wrong | Find out there's no demand after months of building. | Know before you write a line of code, so you build, sharpen, or drop with evidence. |
What the Idea Validator shows you
Real, unprompted signals — the kind that actually predict whether people will install what you build.
Demand, in real words
See actual posts where people ask for your idea, so 'is there a market?' becomes a question you can answer with evidence.
Complaints about alternatives
Frustration with what exists today is your opening. We surface the threads where the current options are letting people down.
Feature requests
Spot the specific things people keep begging for — your roadmap, written by the market before you build.
Signal summary
A clear read on how much demand there is and how loud it is, so you're not eyeballing a wall of links.
Find your positioning
The exact language people use to describe the problem is the language that will make your listing and marketing land.
Build, sharpen, or pivot
Leave with a decision backed by evidence instead of a hunch — before you've written a line of code.
Who it's for
Who the Idea Validator is for
Anyone about to spend real time building something who wants proof there's demand before they commit.
Developers with a shortlist of ideas
You have three ideas and time for one. Validate each against real demand and build the one the market is already asking for.
Founders writing the pitch
You need evidence, not a hunch. Walk into the deck or the build with real posts that prove people want this.
Anyone tempted to just build it
The most expensive way to test an idea is to ship it. Spend minutes checking for demand before you spend months.
Key facts
App Idea Validator at a glance
The most expensive way to validate an app idea is to build it — evidence of demand is cheaper and comes first.
Unprompted public posts predict real demand far better than surveys, where people are polite by default.
Complaints about existing apps are the clearest opening for a new one — that frustration is your wedge.
The words people use to describe their problem are the words that make your store listing convert.
Frequently asked
App Idea Validator, answered
How is this better than asking friends or running a survey?
Friends are kind and surveys are hypothetical. The Idea Validator uses unprompted, public posts — people describing the problem when they had no idea you were listening. That's a far more honest signal of real demand.
What if there's no demand for my idea?
Then you've just saved yourself months of building the wrong thing. Weak signal is a result, not a failure — you can sharpen the idea, pick a different angle, or move on with confidence.
Do I need a finished idea?
No. A sentence or two is enough. In fact, validating early — before you've committed to a spec — is exactly when this is most valuable.
How do you measure demand for an idea?
By finding unprompted, public posts where people ask for your idea, complain about the alternatives, or hack together a workaround, then summarizing how many there are and how strong the frustration is. That evidence predicts real demand far better than a survey.
What counts as a strong signal?
Lots of people describing the problem in their own words, loud frustration with the current options, and repeated requests for the same missing feature. Weak or absent signal is a useful result too — it saves you from building the wrong thing.
