How to find app ideas on Reddit
Consumer apps live and die on one feeling: “this should be easier.” People don’t write specs about it, but they complain to their communities constantly.
Why consumer app ideas are different
A SaaS idea wins when it saves a business time or money, and the business has a budget. A consumer app idea wins when it fits into a person’s life and they care enough to keep opening it. The buyer is an individual spending their own money, which changes how you read the signal.
Two differences shape the whole hunt. The market is huge but willingness to pay per person is small, so you need either a large audience or a passionate one. And retention is the real test, because a consumer can download your app, use it once, and forget it forever. So you’re looking for a problem people return to, talk about repeatedly, and feel emotionally.
Where consumer app ideas hide
App-focused communities are the obvious start: r/androidapps, r/iosapps, r/apphookup, and r/AppIdeas are full of people requesting apps and venting about the ones they use. Read the “is there an app that” posts and the “yeah but it doesn’t do X” replies under recommendations.
The richer signal is in activity communities — the subreddits built around what people actually do: r/running, r/MealPrepSunday, r/personalfinance, r/houseplants, r/Parenting. People there aren’t discussing apps in the abstract; they’re living the activity and bumping into friction. A recurring “how do you all track this” thread is a feature request the community wrote for you.
The signals that point to an app
- “Is there an app that…” with no good answer — a repeated unanswered request is a market asking out loud
- People cobbling together notes apps and spreadsheets — consumers tolerate a lot before they reach for a spreadsheet
- Rage at an incumbent app’s changes — a bought, bloated, or newly-subscription app sends its community looking to leave
- Abandoned apps and “I deleted it because…” — each reason is a design brief for the version that would have kept them
- Strong emotion around a recurring activity — emotion is the hook that makes an app sticky
Read for retention, not just the problem
A problem is necessary but not sufficient. The deciding question is whether people would come back, because an app used once and forgotten earns nothing. Look for evidence the activity is recurring and identity-shaped: a runner logs every run because running is part of who they are; a person splitting one dinner bill does it once and never thinks about it again. The first is an app, the second is a feature.
The strongest retention tell is people who already track the activity somewhere, however badly — a spreadsheet they actually maintain, a notes file they keep updating, a paper log by the door. If the current workaround is annoying yet still kept up, an app that removes the friction inherits a habit that already exists. Watch the comments for streak and ritual language: “day 200 of tracking this,” “I check it every morning.” That attachment to even a clumsy method is the best sign a better app gets opened again tomorrow.
The hard part: will they actually pay?
People say they want an app far more often than they pay for one. Read for the kind of want that opens a wallet:
- People already paying for a worse app and complaining about it — existing spend is the best proof
- People paying for a non-app workaround (a coach, a service, a subscription box) an app could partly replace
- An audience whose hobby already involves spending money — gear, courses, memberships
Two worked examples
Hobby workaround → tracking app. In r/houseplants: “I have 40 plants and can’t track which needs watering. I made a spreadsheet but never check it.” The app schedules reminders per plant and is dead simple to update. This community already spends on plants, pots, and grow lights, so a passionate, spending audience exists.
Incumbent rage → focused alternative. A budgeting app loved in r/personalfinance announces a steep subscription. The sub erupts with “what do I switch to,” each comment naming the two features they can’t lose. A lean budgeting app that nails those features rides the switching moment — and willingness to pay is already proven.
For business software, switch tracks
Consumer apps and B2B SaaS play by different rules. If you’re after subscriptions and budgets, the SaaS guide is the better map.
How to find SaaS ideas on RedditFrequently asked questions
How do I find app ideas on Reddit?
Mine two kinds of communities: app-focused subs like r/androidapps, r/iosapps, and r/AppIdeas where people request and review apps, and activity subs like r/running or r/houseplants where people describe friction in a hobby or routine. Look for unanswered “is there an app that” requests, spreadsheet workarounds, and rage at incumbent apps — then check whether the audience would actually pay.
What kinds of app ideas come from Reddit?
Mostly consumer and mobile app ideas tied to hobbies, routines, health, money, and frustration with existing apps. Reddit surfaces the friction in everyday activities and the gaps in popular apps, which point at focused alternatives or purpose-built tools for a passionate niche. For business software, a SaaS-focused approach works better.
How do I know if people will pay for an app?
Look for existing spend, not enthusiasm. People paying for a worse app, paying for a service the app could replace, or already spending on the hobby are the strongest signals. Generic “I’d use that” comments are weak. Then make sure you can picture a believable revenue model — a paid tier for a passionate niche or ads for a large casual audience.
Are app ideas harder to monetize than SaaS ideas?
Usually yes. Businesses have budgets and pay subscriptions to save time or money, while consumers spend their own money and churn easily. Consumer apps often need either a large audience monetized through ads and in-app purchases or a small, passionate niche willing to pay directly. That makes reading genuine willingness to pay more important for apps.
Which subreddits are best for app ideas?
For direct requests and reviews, r/androidapps, r/iosapps, r/apphookup, and r/AppIdeas. For implied ideas, the activity subreddits around hobbies and routines — r/running, r/MealPrepSunday, r/Parenting, r/personalfinance — where people describe friction without naming an app. The activity communities tend to give richer, less contested signals.
What’s the difference between an app idea and a SaaS idea?
An app idea usually targets consumers doing an activity in their personal life, monetized through paid downloads, subscriptions, ads, or in-app purchases, and lives or dies on retention. A SaaS idea targets businesses with budgets, monetized through recurring subscriptions, and wins by saving time or money. The hunting grounds overlap, but the buyer and monetization differ.
