estimate_strings()
Quick Benchmarks
If you do not know your exact string count yet, these rough ranges are usually enough to model a realistic first pass.
-
Authentication flow
Login, signup, forgot password, and 2FA typically land around 20 to 40 strings. -
Settings and preferences
Profile, notifications, and accessibility settings often land closer to 150 to 250 strings. -
In-app product content
Tours, empty states, tooltips, and upgrade copy commonly add 300 to 600 strings or more. -
Release notes and store copy
You can also model App Store and Google Play release-note text so launch planning is not siloed from the app.
Tip: Export your .xcstrings or Android XML files for an exact count before the next localization sprint if you need a tighter estimate.
