Version Number Format
The version number format for Teachme Biz mobile app is as follows:
The version consists of three numbers separated by dots (.), and each number from left to right is called:
- Major version
- Minor version
- Patch version
Major is the highest level, followed by Minor and then Patch.
Each number is 0 or a positive integer.
Rules for Number Changes
The version number is always updated with each app update, with at least one value increasing.
When a higher-level number increases, all lower-level values are reset to 0.
If the number of digits in any number increases, it does not affect the other numbers.
For example, when upgrading from version 3.1.9 to a new major, minor, or patch version, the new version numbers would be as follows:
| Version type | New version number |
|---|---|
| Major | 4.0.0 |
| Minor | 3.2.0 |
| Patch | 3.1.10 |
Version Number Change Policy
Which number in the version is updated is determined based on the impact to your usage environment.
Major Version
- Very significant feature additions or screen redesigns
- Feature discontinuations or major specification changes that may require prior notification or adaptation within your organization
Minor Version
- Addition of new features or expansion of existing functions
Patch Version

Version Number Correspondence Between Android and iOS Apps
If the major and minor versions are the same, equivalent functionality is available in both apps.
Patch versions are updated separately for each app, so even if the versions are the same, the changes may differ.
Example: Version x.x.3 of the Android app might fix an issue that only occurs on Android 11, while version x.x.3 of the iOS app might fix an issue that only occurs on iOS 26.
