Over-the-Air (OTA) Updates
Wireless delivery of translation updates to apps without requiring app store releases.
Definition
Over-the-Air (OTA) updates for translations allow mobile and web applications to receive new or updated translations without requiring a full app update through the App Store or Google Play. This enables rapid iteration on translations, A/B testing of copy, and instant fixes for translation errors. OTA typically works by the app fetching translation bundles from a CDN at runtime.
Examples
- →Fixing a typo in Spanish translations without waiting for app review
- →A/B testing different call-to-action text across regions
- →Rolling out a new language immediately after translation is complete
- →Updating seasonal marketing copy in real-time
Frequently Asked Questions
Do OTA translations affect app performance?
Well-designed OTA systems have minimal impact. Best practices include: caching translations locally, fetching updates in background, using CDN for fast delivery, and implementing delta updates (only changed strings). Initial load adds a network request, subsequent loads use cache.
Are OTA translation updates allowed by Apple and Google?
Yes, updating text/translations via OTA is allowed. Both platforms permit updating localizable strings, images, and certain content. However, you cannot use OTA to change app functionality or bypass review guidelines.
