Indie ASO on a $0 Budget: What to Do Anyway

Indie app developers often skip ASO because the paid tools are expensive and the agency cost is out of reach. The result is apps that ship with default screenshots, generic titles, and zero keyword strategy — and then wonder why the install graph is flat. The truth is that 70% of ASO work is free if you know what to do. The remaining 30% is where paid tools and agencies add value.

This article is the $0-budget ASO checklist Semnexus recommends to indie developers. Every item below costs nothing but time, and most can be done in a weekend or two.

What you can do for free

The high-leverage ASO work an indie can do without buying anything:

1. Read your competitors' listings carefully

The top 10 ranked apps in your category have already done keyword research. Read their titles, subtitles, short descriptions, and long descriptions. Note every category term that appears in 3+ competitors. That overlap is your initial keyword universe.

Time: 2-3 hours.

2. Mine App Store and Play autosuggest

Type your core category seed terms into both store search boxes. Note every autosuggest completion. Repeat for 5-10 seed terms. You'll surface 50-150 candidate keywords for free.

Time: 1-2 hours.

3. Write a subtitle that says what the app does

The subtitle (App Store) or short description (Play) is the most-skipped optimization on indie apps. Use it to state the app's value in 2-3 high-intent terms. Avoid taglines; favor specifics.

Time: 1 hour.

4. Design the first screenshot to win the tap

The first screenshot drives 60%+ of product page conversion. A clear caption, a real product moment, no app store chrome. You do not need a paid design service; Figma is free and produces excellent results.

Time: 4-8 hours.

5. Write a long description that ranks on Play

Play's long description is the keyword field. Aim for 250-400 words with 8-12 priority terms mentioned 3-5 times each in context. Indie developers who write a strong long description routinely outrank well-funded apps.

Time: 3-4 hours.

6. Set up the in-app review prompt correctly

Native SKStoreReviewController on iOS and Google's In-App Review API on Android. Trigger after a value moment. Cap to platform limits. Free to implement; lifts rating noticeably (see App Store Reviews: Ethical Generation).

Time: 2-4 hours.

7. Localize at least 2 additional languages

Even one strong localization unlocks a separate indexing pass on iOS. For Play, localized descriptions improve conversion. Use a real translator (a friend or fiverr), not pure LLM translation.

Time: 4-8 hours per locale.

8. Add accurate Privacy nutrition labels and Privacy Manifests

Required by Apple in 2026, scored by Play. Filling these out accurately also improves App Store conversion because users prefer apps that don't over-claim data collection.

Time: 2-3 hours.

What costs almost nothing

Items where free tools handle most of the work:

AppFigures free tier or App Annie's free dashboards. Basic visibility into rank.
Google Trends. Free search-volume directionality (not absolute volumes, but trends).
Apple Search Ads keyword popularity index. Free inside the ASA Advanced UI; useful for sanity-checking volume even if you don't run ads.
Free icon and screenshot mockup tools. Figma Community has dozens.

When paid tools genuinely add value

The 30% where paid tools are worth it:

Keyword difficulty and volume scores. AppTweak, ASOMobile, Sensor Tower start at roughly $100-$200 per month. Indie monthly pricing is reasonable for one app.
Competitor visibility tracking. Knowing when a competitor changes metadata is hard to do free.
Screenshot A/B testing at scale. Native A/B testing tools work for free; paid platforms add reporting.

These are upgrades, not requirements. An indie app can do well-ranked ASO on $0 first.

The $0 30-day plan

A working schedule for an indie developer:

Week 1. Competitor analysis and autosuggest mining. Build the 50-150 keyword universe.

Week 2. Write the title, subtitle, short description, long description. Ship the metadata update.

Week 3. Design screenshot 1 and 2 from scratch. Ship the asset update.

Week 4. Implement the in-app review prompt. Test the value-moment trigger. Submit.

After 4 weeks, wait 14-28 days for the algorithm to recompute. Measure the change in rank, conversion, and install volume.

Five mistakes indie developers make

Set-and-forget metadata. The first ASO pass is a baseline, not a final state. Plan a quarterly refresh.
Writing a generic subtitle. "The best [category] app" is wasted. Use the characters for intent terms.
Skipping the long description on Play. Treating it like marketing copy. Treat it like the keyword field it is.
Designing screenshots that look like every other app. Visual distinctiveness compounds with ranking.
Not setting up the review prompt. Free lift left on the table.

Frequently asked questions

Is paid ASA worth it for an indie? Often yes, even at small budgets ($50-$200 per week). ASA brand defense and category coverage are some of the highest-ROI paid app spend.

How do I research without a paid keyword tool? Autosuggest + competitor analysis + Apple Search Ads keyword popularity = most of what a paid tool provides.

What about preview videos? Optional for indie. Strong screenshots usually outperform a weak preview video. Add a video only when you can do it well.

How long until ASO changes show in rank? 14 to 28 days for new metadata. Conversion changes faster (within a week).

Is there an indie-specific ASO community worth joining? Yes. r/iOSProgramming, the Indie Hackers ASO threads, and the Apple Developer forums have active practitioners. Ask specific questions; they're often answered well.
