We plan to fully deprecate and remove Mobile Application Designer version 3 from AppMaster Studio on January 1, 2026 for all non-enterprise users. LTS and Enterprise customers can keep using v3 at least until mid-2027, but we strongly advise to start migration process to v4 as soon as possible.
Since April 2025 there is no option to create v3 mobile applications in Studio UI, but all existing applications will be available until the cut-off date.
If you need to keep your v3 mobile application after the cut-off date, please contact us so we can export all bundles and apk/aab/ipa files for you prior to the cut-off date. In a case if you have not additional mobile application available in your current subscription, but you want to start migration to v4 we will upgrade your subscription for free for the period of migration.
We understand that any non-backward compatible changes always bring a lot of additional work to rebuild mobile applications, but unfortunately there is no other way for us to build drastically more performant and comprehensive mobile applications without full architectural overhaul.
