File Size:

• ARM Version: 22.1MB (recommended for 99% of modern smartphones)
• Universal Version: 35.3MB (for maximum compatibility)

Minimum Requirements:

• OS: Android 5.0 (Lollipop) or higher
• RAM: 2GB minimum (recommended 3GB+ for smooth performance)
• Storage: 200MB free space for installation and data

Performance: The app runs smoothly on entry-level devices and optimally on mid-range and above. Our testing shows stable performance on devices with 2GB+ RAM.

SHA-256 verification is a CRITICAL security step to ensure the APK file is authentic and has not been modified:

Verification Steps:

1. Download "Hash Calculator" or "Hash Droid" from the Google Play Store (free)
2. Open the app > Tap "Select File"
3. Navigate to Downloads > Select tkpk.apk
4. Choose algorithm "SHA-256" > Tap "Calculate"
5. Wait 30-90 seconds for the result
6. Compare the generated hash with the official hash on the website
7. Hash MUST match 100% — even 1 character different = file compromised!

Official SHA-256 Hash:

⚠️ CRITICAL: If the hash does NOT match, DO NOT install! Delete the file and download again from the official source.

Main differences:

Size	37% smaller	Larger
Compatibility	ARM/ARM64 (99% phones)	All architectures
