Rename Examples

Copied!

# Rename format:
# {DisplayName}-({BundleID})-{AppVersion}-(iOS_{MinVersion})-{MD5Hash}.ipa

# Example: Rename a single file
ipachecker MyApp.ipa --rename
# Result: MyApp-(com.company.myapp)-1.2.3-(iOS_13.0)-abc123...ipa

# Batch rename all IPAs in a folder
ipachecker --batch-analysis /path/to/ipas --rename

# The rename feature:
# Only renames local files (not downloads unless --dont-delete used)
# Skips files already in obscura format
# Won't overwrite existing files
# Handles permission errors gracefully
# Works with both single and batch analysis
