Developer tools is the one category where ASO conventional wisdom inverts. Lifestyle screenshots underperform technical specificity. Marketing copy underperforms feature lists. 'Beautiful design' is irrelevant; 'SSH key generation, port forwarding, Mosh support' is everything. The top 10 dev-tool apps read like specs sheets, and that's exactly why developers download them.
Title says exactly what it is ('Working Copy — Git client'). Screenshots show real code diffs, not stock UI.
Termius
Description front-loads protocol support — SSH, Mosh, SFTP, port forwarding. No fluff.
Pythonista 3
Subtitle "Python Scripting" hits the exact developer query. Screenshots show real code with output.
Common ASO mistakes in developer tools
⛔️Lifestyle screenshots (a developer at a cafe). Developers want to see your app's actual UI rendering real code or output.
⛔️Vague feature lists ("powerful", "fast", "intuitive"). Developers ignore adjectives and scan for verbs/protocols/integrations.
⛔️Missing technical keywords (SSH, Git, REST, GraphQL, webhook, etc.) in the keyword field. These are the high-intent searches.
⛔️Forgetting Mac/iPad/iPhone form-factor positioning. Many dev tools sell on iPad-as-replacement-for-laptop — say so explicitly.
What top developer tools do well
✅Title and subtitle are dense with technical specificity ("Git client", "SSH terminal", "Python scripting").
✅Screenshots show real code, real output, real diffs. Stock placeholder code reads as fake to developers.
✅Description is a feature list with version numbers and protocol support. Marketing copy is minimal.
✅Keyword field stuffed with technical terms — every protocol, language, integration the app supports.

Developer Tools ASO FAQ
Should my developer tool app use lifestyle screenshots?
+
No. Developers convert on capability and specificity, not aspirational imagery. Top 10 developer-tool apps almost exclusively show real code, terminal output, or actual UI — not someone holding a phone at a cafe. Floyd flags lifestyle shots as a warning for any app in the Developer Tools category.
Should I list every protocol my app supports in the title?
+
In the subtitle, yes — that's the ranking field. The title should still be the brand + primary verb. "Termius" + "SSH, Mosh, Telnet, Port Forwarding" works because the subtitle does the keyword work and the title stays clean.
