App Store and Google Play listing editor, in practice
The gap in most keyword tools is the last step: you found the phrases, and now you open App Store Connect in another tab and retype them. aso.best closes it. Connect an App Store Connect API key of your own, and the dashboard lists your apps, finds the version that is currently editable, and shows every locale as a tab with the fields Apple lets you change: name and subtitle on the app info, keywords, promotional text, description, what's new and the two URLs on the version.
The keyword field is where tracked keywords pay off. Every phrase you track for that app is shown as a chip beside the field, ordered by your current position, and one click appends it, comma-separated, inside the 100-character limit. The counters count like App Store Connect counts, so what fits here fits there. Saving writes the fields to Apple through the official API. It does not submit the version for review, and it never will from aso.best: the release decision stays on Apple's site, in your hands.
The same key reads your customer reviews with the replies you already gave, and lets you reply from the page. Keys are stored encrypted and can be removed at any time; removing one here does not revoke it at Apple, so revoke it there too when you no longer need it. Reading, counting and the keyword chips are free; saving and replying are Pro.
