The Real Cost

App Store Translation the Old Way Hurts

  • Agencies charge $3-5K per language batch. 4-6 week turnaround.
  • German translations run 30% longer than English. Character limits break.
  • Copy-pasting metadata into 40 ASC locale fields takes days per app.
  • Every version update means re-translating What's New for 40+ locales.
Localizer Mate Fixes This

  • Direct ASC push: Translations upload straight to App Store Connect. No CSV exports.
  • Smart condensing: German text too long? Auto-trimmed to fit ASC character limits.
  • Batch mode: Localize 10 apps at once. Ship a whole portfolio in an afternoon.

Smart Condensing for Character Limits

German runs 30% longer than English. That blows past the 4000-char description limit and the 170-char promo cap. Smart condensing trims translations to fit while keeping the meaning intact.
