Settings & platforms

Settings

Appearance

• Language — 30+ UI locales. Takes effect immediately.
• UI theme — light, dark, or follow system.
• Wi-Fi channels shape — parabola (default), trapezium, trapezium filled, rectangle, triangle, oval, bubbles. Changes how APs are drawn on the channel graph.

Defaults for ping-based tools

These values are used by every tool that sends ICMP — Ping, Host monitor, Network map, Hosts in range.

• Packet size — 24–1024 bytes, default 32.
• Timeout — 1–2147 seconds, default 1 s.
• Concurrent pings — parallelism ceiling for sweeps (Network map, Hosts in range, Host monitor ping-all). Default 10, range 1–50.

Higher concurrency completes sweeps faster but can drown cheap Wi-Fi chipsets in ARP traffic. Stick to 10–15 on battery, bump up on wired Desktop.

Terminal (built-in SSH client)

• Font size — Small / Medium / Large (10 / 15 / 20 px).

Sound

• Ping beep — per Ping-screen toggle (Off / On success / On failure) is persisted here; can also be changed inline on the Ping screen.

Privacy & data

• Share diagnostic data — opt-in Firebase Analytics / Crashlytics. Off keeps all telemetry local.
• Privacy policy — fetched live from the DR-ONLINE website; a bundled fallback is used if offline.

PRO & billing

The free tier shows an ad banner and limits: total saved hosts (Host monitor), DNS propagation sweeps (one per install), and some cross-tool conveniences. The Upgrade entry opens the store (Google Play / App Store) with:

• Subscription — weekly / monthly / quarterly / yearly.
• Lifetime — one-time purchase.
• Restore purchases — for reinstalls or new devices on the same account.
• Manage subscription — opens the store's subscription page.

Platforms

Android

• Min SDK 26 (Android 8). Target 35 (Android 15).
• Free tier with ads — banner plus interstitials between screens. PRO removes all ads.
• Permissions:
  • Fine location — required for Wi-Fi scan (SSIDs are location-restricted on Android 8.1+).
  • Local network — implicit; Bonjour/mDNS and ping sweeps just work once the device is on Wi-Fi.
• Android TV — full TV layout with d-pad navigation. Shared codebase, separate TV composables for screens that benefit from bigger-text views.

iOS

• Distribution — App Store. TestFlight for public betas.
• Free tier with ads, PRO removes them (same IAP options as Android).
• Permissions:
  • Local Network — required for Bonjour/mDNS and any IP-level scanning. The system dialog appears the first time such a tool is opened.
  • Location — required for Wi-Fi scan on iOS 13+. Without it SSIDs are not exposed to apps.
• Cellular-only sessions have no access to the LAN — Bonjour/mDNS and subnet sweeps show a clear notice.

Desktop (Windows, macOS, Linux)

• JVM 17 runtime, bundled with the installer. No separate Java install needed.
• No ads on Desktop.
• Portable mode — the desktop app keeps its data under ~/.dr-nettools/ (%APPDATA%\DR-NetTools\ on Windows). Copy the folder between machines to bring your host groups with you.
• Permissions — no special system permissions for most tools. Raw ICMP on Linux uses unprivileged SOCK_DGRAM where available; otherwise falls back to user-space. Wi-Fi scan depends on OS APIs being available (macOS Location Services, Windows WLAN API, Linux nl80211).

Licences

The About → Open Source screen lists every third-party component shipped in the app with its licence text. DR-ONLINE's own libraries (DR-SSH-MP, DR Network Library) are proprietary and redistributed only within DR-ONLINE apps. DR-Logger is open source (MIT).

Reporting issues

Bug reports: include the platform, app version (shown on the About screen), and reproduction steps. If it's a network-specific problem, attach the output of the affected tool using Share.
