To market a mobile app with little or no budget, fix your App Store and Google Play listing first, then post short-form videos about the problem your app solves, join the communities where your users already talk, and turn early users into referrers. Free channels cost time instead of money, so pick two or three and work them every week for at least 90 days. Paid ads come later, once you know your store page converts and users stick around.
This playbook is the order we would follow if we were launching an app tomorrow with a budget close to zero. It works for consumer apps, productivity tools and niche utilities. Numbers below are illustrative unless stated otherwise.
Why low-budget app marketing starts with retention, not installs
Before spending a single hour on promotion, check whether people who install your app come back. If most users open it once and never return, every free channel will feel like it "doesn't work", because you are pouring water into a leaky bucket.
A quick sanity check:
- Day-1 retention: what share of new users open the app again the next day?
- Day-7 retention: what share are still active a week later?
- Activation: what share reach the moment the app first delivers value (first habit logged, first workout completed, first file scanned)?
Benchmarks vary a lot by category, so compare yourself with your own previous cohorts rather than a generic number. If retention is weak, spend the first two weeks on onboarding and the "aha" moment. Marketing amplifies a product; it can't replace one.
Step 1: Make your store listing convert (free ASO)
App Store Optimization (ASO) is the process of improving your app's store page so it ranks for relevant searches and turns more visitors into installs. It is the highest-leverage free channel because every other channel sends people to this page. Our full ASO guide goes deeper; here is the minimum.
- Title and subtitle: include the main thing people search for, not only your brand name. "Fokus" says nothing; "Fokus: Study Timer and Focus" does.
- Keywords: list 20–30 phrases your users would type, then use the most relevant ones in the fields each store indexes (check Apple's and Google's current documentation, since the indexed fields differ).
- Screenshots: the first two or three do most of the work. Show the outcome, not the menu. Add a short benefit caption on each.
- Preview video: optional, but a 15–30 second clip of the core action often helps for visual apps.
- Ratings: ask for a review right after a success moment using the native review prompt, never after an error or paywall.
- Localisation: translating the listing into two or three languages where you have demand is cheap and can open new search traffic.
Track your store page conversion rate (installs divided by product page views) in App Store Connect and Google Play Console. Small changes to screenshots can move it noticeably, so test one change at a time.
Step 2: Short-form video on TikTok and Reels
Short-form video is the best free discovery channel for most consumer apps, because the algorithm can show a brand-new account to thousands of people if the first seconds hold attention. You don't need production. You need a phone, a screen recording and a clear hook.
Formats that tend to work for apps:
- Problem, then demo: "If you forget to drink water, watch this", then show the app solving it in eight seconds.
- Before and after: a messy budget becomes a clear one; a chaotic week becomes planned.
- Founder diary: "Day 14 of building an app for nurses. Here's what users asked for this week."
- Reply to comments: answer real questions with a video, which doubles as social proof.
Aim for one video a day for 30 days rather than one polished video a month. Most will get modest views; a few will break out, and those tell you which angle to repeat. Our 20 hook templates give you a month of starting points.
Step 3: Community marketing on Reddit, Discord and forums
Your users already gather somewhere: subreddits, Discord servers, Facebook groups, niche forums. Community marketing means becoming a useful member of those spaces so people discover your app through you, not through ads.
How to do it without getting banned:
- Read the rules of each community first. Many ban self-promotion or allow it only in specific threads.
- Contribute for two to three weeks before you mention your app. Answer questions, share what you learned.
- Share the story, not the pitch. "I built a habit tracker because every other one punished me for missing a day. Here's what I learned from 200 beta users" invites discussion; "Download my app" invites removal.
- Ask for feedback, which most communities welcome and which gives you product insight for free.
Reddit in particular rewards honesty and punishes marketing speak. Our Reddit marketing guide covers subreddit selection, post formats and what moderators look for.
Step 4: Founder-led content on X, LinkedIn and Threads
Building in public means sharing your progress, numbers and lessons openly while you build. It works because people like to follow a story and back someone they've watched grow. For apps it is especially useful for reaching early adopters, journalists and other founders who may share you.
Keep it simple: one post a day about a real thing that happened (a user email, a bug, a metric, a design decision), and one longer thread a week about a lesson. Engage with others in your niche for 15 minutes a day; on most platforms replies grow a small account faster than original posts.
Step 5: Referrals and in-app sharing
A referral loop is a mechanism where each user brings in new users, which makes it the cheapest acquisition channel once it works. You don't need a complex system to start.
- Make sharing useful: shareable results, streak cards, progress images or invite links for shared lists.
- Reward both sides with product value: a free premium week for the inviter and the invitee usually costs you little.
- Ask at the right moment: after a success, not on day one.
Measure it with a simple viral factor: invites sent per user multiplied by the share of invites that convert. If 100 users send 50 invites and 20% install, you get 10 extra users, or 10% free growth on top of every other channel.
Step 6: Micro-creators on a small budget
When you have a few hundred dollars, micro-creators (roughly 5,000 to 100,000 followers) are often the next best step. Many will post in exchange for a lifetime subscription or a small fee, and their audiences tend to trust them more than large accounts.
Start with 5–10 creators whose audience matches your user, give them a short brief with the problem, the hook ideas and one call to action, and track installs per creator with unique links or codes. As one reference point, a productivity app we worked with reached 48,000 installs in 45 days from 30+ TikTok and Reels micro-creators, with a 4.2x return on creator spend; you can read how in our creator and Reddit case studies. That result depended on the product and the category, so treat it as a sign of what's possible, not a promise.
Step 7: Free PR, launch sites and directories
- Product Hunt: a good launch can bring a spike of early adopters and backlinks. Prepare it properly rather than launching on a whim.
- App directories and "alternative to" sites: list your app wherever people compare tools in your category.
- Niche newsletters and podcasts: a short, personal pitch with a story angle ("a nurse built an app for night shifts") beats a press release.
- Your own website: a simple landing page with a few helpful articles can rank for long-tail searches and send steady traffic over time.
A 90-day plan for marketing an app with no budget
Days 1–14: foundation
- Fix onboarding and measure Day-1 and Day-7 retention.
- Rewrite title, subtitle and first three screenshots.
- Set up attribution basics: store analytics plus unique links per channel.
Days 15–45: content and community
- Post one short video a day; review the numbers every Friday.
- Join three to five communities and contribute daily.
- Share one founder update a day on X or LinkedIn.
Days 46–90: loops and leverage
- Launch a simple two-sided referral reward.
- Test 5–10 micro-creators with a small budget or free subscriptions.
- Double down on the one or two channels that bring retained users; drop the rest.
How to measure what's working
Installs are not the goal. Paying or retained users are. For each channel, track installs, activation rate and, if you charge, trial-to-paid conversion. Then calculate cost per retained user, counting your own hours at a fair rate. A channel that brings 1,000 installs with 5% activation is worse than one that brings 300 with 30% activation.
When you eventually add paid ads, compare their customer acquisition cost against these free channels. Our guide on how to lower CAC shows the formulas.
Key takeaways: fix retention before promotion; your store page is the first free channel because every other channel lands there; post short videos daily and keep the winning angles; be useful in communities before mentioning your app; build a two-sided referral reward; judge channels by retained users, not installs.
Frequently asked questions
Can you really market a mobile app with no budget?
Yes, but "no budget" means paying with time instead of money. ASO, short-form video, community participation, founder content and referrals all cost nothing except hours. Expect to spend 10–15 hours a week for at least 90 days before you can judge the results fairly.
What is the best free way to promote a new app?
For most consumer apps it is a combination of ASO and short-form video on TikTok and Instagram Reels. ASO improves conversion of every visitor, and short video can reach new audiences without followers. B2B or niche utility apps often do better with Reddit, forums and founder-led content.
How many downloads should a new app expect in the first month?
There is no reliable average, because it depends on category, competition, store ranking and how actively you promote. A better question is how many retained users you gained and which channel brought them. Set a weekly target for one channel and adjust after four weeks of data.
Is ASO enough to grow an app on its own?
ASO alone is rarely enough for a new app, because ranking for competitive keywords takes downloads and ratings you don't have yet. It works best as the conversion layer under other channels. Once outside traffic starts arriving, a well-optimized store page turns more of it into installs and helps your rankings over time.
When should I start paying for app install ads?
Start paid ads when your store page converts well, Day-7 retention is stable and you know what a user is worth. Without that, ads mostly buy users who leave. A small test budget can also be used to boost organic videos that already performed well, which is usually cheaper than cold ads.
