Question 1

What are the character limits for App Store and Google Play descriptions?

Accepted Answer

Each store has hard character limits. On the Apple App Store: title 30 characters, subtitle 30 characters, promotional text 170 characters, keywords field 100 characters comma-separated, and long description up to 4000 characters. On Google Play: title 30 characters, short description 80 characters, and full description up to 4000 characters. Only the first 3 lines of the long description (about 250 characters) appear before the read more fold, so those lines carry the most weight in the install decision. This tool respects every limit and shows character counts inline so you never have to trim manually.

Question 2

How does the App Store search algorithm decide which apps rank for a keyword?

Accepted Answer

The Apple App Store indexes three fields for search: the title, the subtitle, and the keywords field. It does NOT index the long description for search ranking — that field is only for conversion. Google Play works differently: it indexes the title, the short description, and the entire full description. That is why a good listing for Play strategically repeats 3-5 primary keywords two to three times across the full description. In practice, this means you write one high-conversion listing but tune the keyword placement differently for each store — which is exactly what this generator does.

Question 3

What makes a strong iOS keywords field?

Accepted Answer

You have exactly 100 characters, comma-separated, no spaces after commas. Every wasted character costs a keyword. Four rules: one, never repeat words that already appear in your title or subtitle — the App Store combines them automatically. Two, prefer single words over phrases; the App Store recombines singles into phrases on its own. Three, do not include both plural and singular of the same word — the algorithm handles inflection. Four, avoid competitor brand names, which are a common rejection reason. The goal is to spend all 100 characters on unique, single-word search intents that do not appear elsewhere in your indexed metadata.

Question 4

How important is the first 3 lines of the app description?

Accepted Answer

Extremely important. On both the App Store and Google Play, only the first three lines of the long description — roughly 250 characters — appear above the read more fold. Data from ASO platforms consistently shows that fewer than 5 percent of visitors tap read more. That means those 250 characters are the ENTIRE description most users ever see. A strong hook opens with the single biggest user benefit in one punchy sentence, follows with proof or specificity, and closes with what happens if they install. Everything below the fold is for the small minority of high-intent skimmers and the search algorithms.

Question 5

Should I use emojis, bullets, or markdown in my app store description?

Accepted Answer

Use emojis and unicode bullets — they measurably improve skim-through and install rates. Do NOT use markdown syntax like double asterisks for bold or hash for headings. Both stores render descriptions as plain text, so markdown just appears as literal characters and looks broken. The pattern that consistently converts: open with the hook paragraph, then a feature list with a unicode bullet and an emoji leader per line ("• 🔥 Feature name — one-line benefit"), then a short trust or social-proof line, then a soft call to action. Avoid ALL CAPS shouting, exclamation stacking, and generic phrases like "the best app for" that add zero information.

Question 6

Can I use these AI-generated descriptions directly, or do I need to edit them?

Accepted Answer

Treat the output as a strong first draft, not a final. The AI produces copy that respects every character limit, follows current ASO best practices, and reads naturally — enough that many indie developers ship it verbatim. However, three things are worth reviewing before you paste it into App Store Connect or Google Play Console: one, the app name and any specific numbers or claims (the AI may invent plausible-sounding metrics you have not earned yet). Two, the tone — make sure it matches your brand voice. Three, the keywords field — cross-check against your existing App Store Connect keyword research. Fifteen minutes of editing usually turns a good AI draft into a listing that converts.
