six tools you'd otherwise stitch together.
Every App Store Connect tab gets a Mac-native panel — and a way to translate, generate or ship without bouncing back to the browser.
// Metadata
Every locale, side-by-side.
Pull title, subtitle, description, keywords and What's New from App Store Connect once. Edit in one grid that respects every length limit — then translate missing fields to every locale with Claude, your brand voice and protected terms enforced.
- ✓ Live 30 / 30 / 4 000 char counters per cell
- ✓ Per-app brand voice, glossary, protected terms
- ✓ Atomic Push with full diff preview
// Screenshots
Native screenshots, no Figma.
Real iPhone 6.9″, iPad Pro and Mac device chrome. Drop in your captures, layer text, pick a theme — and translate every text layer to all your locales in one click. Each design auto-routes to the correct device row when you Add to Screenshots.
- ✓ iPhone 6.9″ · iPad Pro 13″ · iPad Pro 11″ · Mac
- ✓ Per-locale text variants from one source canvas
- ✓ Click-to-zoom lightbox + Mac-native export
// ASO
Track keywords. Watch the field.
Add the keywords your users actually search. Asomium logs your rank, popularity, difficulty and opportunity score per keyword × locale, daily. Stack competitors next to your app to compare what they target — find what's actually working in your category, not what a vague dashboard claims.
- ✓ Per-keyword popularity · rank · difficulty · opportunity
- ✓ Auto-discover via App Store autocomplete sweep
- ✓ macOS notifications when ranks shift overnight
- ✓ Stacked competitor comparison view
// Ship
Archive, upload, submit — one click.
Asomium runs xcodebuild archive, exports the .ipa, uploads to App Store Connect, auto-attaches the build to your editable version, and unblocks Submit-for-Review. Need testers first? One sheet sends the same build to your TestFlight beta groups — "What to test" notes included. Smart build-number bump prevents the "duplicate build" rejection every indie has hit at least once.
- ✓ Smart CFBundleVersion bump across machines
- ✓ Auto-attach + Submit gate sync
- ✓ TestFlight beta submission with per-group "What to test"
- ✓ Live log + processing-state poll loop
// Revenue
Sales + funnel, in the same window.
Pull Sales Reports + Apple Analytics (impressions → page views → first-time downloads → proceeds) on demand. Hover-scrub the chart, drill into a country or SKU, overlay your own metadata pushes + keyword shifts on the timeline, then ask AsoAI what actually moved the needle.
- ✓ 30 / 90 / 365-day proceeds + period-over-period delta
- ✓ Conversion funnel via Apple Analytics Reports API
- ✓ Country, SKU + discovery-source breakdowns
- ✓ Push / keyword / version events overlaid on the chart
- ✓ "Ask Claude what happened" honesty-constrained analysis
// Workspace
All your apps. One sidebar.
Every app context (iOS · iPadOS · macOS · tvOS · visionOS) on one row. Per-app credentials, brand voice and glossary scoped exactly where they belong. New apps get a coachmark tour that walks the whole flow.
- ✓ 5 platforms · Live + Next contexts per platform
- ✓ Per-app ASC credential override
- ✓ Coachmark tour for new app onboarding
One click. Five extra English storefronts.
Most indie devs ship to en-US and leave en-AU, en-CA, en-GB, en-IN, en-SG empty — forfeiting ranking in five high-intent storefronts to whoever bothered to fill them in.
Asomium's Translate menu has Expand to all English locales — one click clones en-US across all five English variants, with Claude tweaking spelling (color/colour), slang and market norms. Suddenly your app is indexed in six English storefronts instead of one.
That alone has paid for Asomium on the apps we ship it with.
ASO is one tab. Asomium is the whole window.
Other tools cover keyword research really well. Asomium covers it too — and the four other surfaces you'd otherwise patch together by hand.
// without asomium
- ✗ Click through the ASC web UI to update each locale, one form at a time
- ✗ Translation in a separate tab, then paste back, then realise it's 3 chars too long
- ✗ Mock screenshots in Sketch, export per device, upload one-by-one per locale
- ✗ ASO + revenue + competitor analysis in three different paid SaaS tabs
- ✗ Build, archive, upload, attach to next version, submit — five separate manual steps
- ✗ Wait until you're back at the Mac to ship a hotfix
// with asomium
- ✓ One grid for every locale of every app — edit side-by-side with live char counts
- ✓ Claude translations w/ brand voice + glossary, respecting char limits at push time
- ✓ Design one screen → Asomium renders the full localised set, auto-translated text overlays
- ✓ All three in one native window. Real keyword ranks, real revenue, real competitor metadata
- ✓ One button. Self-heals when Apple complains about encryption / support URL / missing build
- ✓ Drive the whole pipeline from Claude Dispatch on your phone, via MCP
