A simple yet powerful Android application that allows you to change the TTL (Time to Live) value on your rooted device.
- 📖 Read & Write TTL — Instantly read the current IPv4 TTL value and write a new one
- 🌐 IPv6 Support — Toggle IPv6 hop limit modification alongside IPv4 TTL
- 🔁 Apply on Boot — Automatically apply the last saved TTL value when your device boots up
- 📱 One-Tap Widget — Add a home screen widget to apply your saved TTL value with a single tap
- ⚡ Quick Presets — Common TTL values (64, 65, 128, 255) available as one-tap presets
- 🔄 Reset — Instantly reset TTL back to default (64) with iptables cleanup
- Rooted Android device — The app requires root (su) access to modify system network parameters
- Android 7.0+ (API 24+)
- Superuser manager (Magisk, SuperSU, etc.)
The app modifies the following system files via root shell commands:
| Feature | System Path |
|---|---|
| IPv4 TTL | /proc/sys/net/ipv4/ip_default_ttl |
| IPv6 Hop Limit | /proc/sys/net/ipv6/conf/all/hop_limit |
Additionally, it sets iptables/ip6tables rules in the mangle table's POSTROUTING chain for session-level persistence.
- Open the project in Android Studio
