YouCouldShipThis vs BigIdeasDB: iOS App Opportunities vs SaaS Ideas

BigIdeasDB is a solid product. It aggregates business ideas from Reddit threads, G2 reviews, and social platforms, then packages them into a browsable database of SaaS and startup ideas. They've built a suite of free tools around it too, including calculators for burn rate, break-even, churn, MRR, and SaaS valuation. If you're looking for your next web-based business, it's a legitimate place to start.

YouCouldShipThis does something fundamentally different. We analyzed 982,572 iOS apps and hundreds of thousands of App Store reviews to find 14,271 concrete app opportunities where the existing app is broken, abandoned, or hated by its own users. It's not a list of ideas. It's a dataset of gaps in the App Store, each one backed by real demand data.

Both products help you find something to build. The difference is what you want to build and how much validation you want before you start.

The core difference: ideas vs. evidence

BigIdeasDB is an idea database. Someone on Reddit says "I wish there was a tool that does X," and BigIdeasDB captures that as a potential business. It's a great starting point, but it's still a starting point. You see the idea, and then you have to figure out whether enough people actually have this problem, whether they'll pay for a solution, and whether someone else already built one.

YouCouldShipThis skips that entire phase. Each entry in our dataset comes with the validation already done. The app has thousands of ratings (demand is proven). It charges money and people are paying (willingness to pay is confirmed). The reviews spell out exactly what's wrong (the feature spec writes itself). We've checked how many well-rated competitors exist. We've estimated the revenue.

Reddit complaints tell you what people say they want. App Store data tells you what people are already paying for, even when the product is terrible.

What you actually get

Where BigIdeasDB wins

Let's be honest about this. BigIdeasDB does several things well that we don't even try to do.

Breadth of business types. BigIdeasDB covers SaaS, web apps, marketplaces, and service businesses. If you don't know what kind of thing you want to build yet, their broader scope helps you explore. We're laser-focused on iOS apps, period.

Free tools. Their burn rate calculator, churn calculator, MRR tracker, and SaaS valuation tool are genuinely useful. Even if you end up building a mobile app, these tools help you think about the business side. We don't have anything comparable.

Ongoing updates. BigIdeasDB continuously adds new ideas as they surface on Reddit. Our dataset is a snapshot of the App Store at analysis time. Both approaches have tradeoffs. Theirs stays fresh. Ours goes deeper on each entry.

Where YouCouldShipThis wins

If you're building iOS apps specifically, the advantages stack up fast.

Real demand data, not social media signals. An app with 5,000 ratings and a 2.0-star average has thousands of active, paying users right now. That's not the same as a Reddit thread with 47 upvotes. Both are signals, but one comes with receipts.

Revenue you can estimate. When a paid app is on the charts, you can do the math. We include revenue estimates for every relevant entry. You know the approximate size of the prize before you write a line of code.

The research is done, not just started. Each entry includes an opportunity score, revenue estimate, top user complaints (extracted from actual reviews), a competition check, and a build difficulty rating. BigIdeasDB gives you a thread to pull. We give you the whole sweater.

One price, no subscription. $99, you own it. No monthly fee, no tier gating, no "upgrade to see the good stuff." Every entry in the dataset is yours.

The audience question

This really comes down to who you are as a builder.

Use BigIdeasDB if:

• You want to build a SaaS product, web app, or online business
• You're still exploring what type of product to build
• You want ongoing idea flow rather than a single deep analysis
• You value free tools for SaaS financial planning

Use YouCouldShipThis if:

• You want to build iOS apps specifically
• You're a Swift developer, indie hacker, or mobile-first builder
• You want demand that's proven by App Store data, not social media
• You want every opportunity pre-scored with revenue estimates, complaints, and competition data
• You'd rather pay once than subscribe monthly

Can you use both?

Honestly, yes. They complement each other more than they compete.

BigIdeasDB might surface a problem space you hadn't considered. Our dataset might show you the specific iOS app in that space that's broken and waiting for a replacement. BigIdeasDB's SaaS valuation tools can help you think about the business model. Our data tells you what users are already willing to pay.

But if you're forced to pick one and you know you want to build for the App Store, the choice is straightforward. You want data from the App Store. You want demand that's measured in downloads and dollars, not Reddit karma. And you want the research already done so you can skip straight to building.

That's what 14,271 scored opportunities look like. 982,572 apps analyzed. Every entry scored, tiered, and ready to evaluate. Not a list of ideas someone thought sounded good. A dataset of gaps in the market, backed by the numbers to prove it.
