Were you once a 91 Assistant user? This once-popular mobile management tool carried many people's memories. From jailbreaking to app downloads, 91 Assistant played an important role in the early days of smartphones.
However, with the rapid development of the internet, we must bid it farewell. This article will help you smoothly transition to a new management method by analyzing the reasons behind the shutdown of 91 Assistant and introducing suitable 91 Assistant alternatives for both Android and iOS users.
On August 31, the 91 Assistant team announced that due to business adjustments and product iteration needs, the 91 Assistant app will completely shut down all services at 23:59 on September 27, 2025, including but not limited to phone connection management, file transfer, app installation/uninstallation, system cleaning, and other functions.
If you have backup needs, you must complete the data backup during this period, otherwise, the data will be permanently lost and cannot be recovered in any way. In addition, 91 Assistant will refund users who are still within their membership period, but users need to apply for the refund proactively. Users who do not apply for a refund will not be refunded. The deadline for refund applications is 24:00 on September 15, 2025, and no applications will be accepted after that.
There are several main reasons behind the shutdown of 91 Assistant:
Outdated Technology: With the continuous updates of Android and iOS operating systems, 91 Assistant failed to keep up with version upgrades, leading to its compatibility and functionality gradually falling behind. This was especially true in the closed iOS system and the open Android ecosystem, where 91 Assistant could not provide timely technical support.
Intense Market Competition: With the rise of other mobile management tools and cloud services, 91 Assistant’s market competitiveness gradually declined. Many emerging tools performed better in user experience, functional innovation, and other aspects, attracting a large number of users.
Policy Changes: With the changes in app store policies, the use of certain functions was restricted, and some of 91 Assistant’s services were affected, especially in app distribution and data backup. Faced with policy constraints, 91 Assistant could not adapt.
Changes in User Needs: With the increasing sophistication of smartphone operating systems, many functions that 91 Assistant originally provided, such as data synchronization and file management, have been replaced by the system itself or other third-party apps. Users' needs have changed.
Abuse of Permissions: To achieve certain functions, 91 Assistant required access to sensitive phone permissions, such as reading contacts, text messages, and call records, raising user concerns about data security and privacy protection.
With the shutdown of 91 Assistant, how should Android users manage their phones? Here are four great replacement tools, each with its own features to meet different user needs.
