he iPhone's status bar, lock screen, and most native clock displays show time only to the minute (e.g., 3:45). For scenarios where you need precise second-level accuracy—such as timing experiments, syncing with external devices, live streaming countdowns, sports tracking, or simply wanting that extra level of precision—iOS doesn't offer a built-in option for always-visible seconds.

Fortunately, Device Status⁺ provides a clean, practical solution: a floating second clock that shows real-time time down to the second (HH:MM:SS) in an always-on, draggable overlay window.

What is Device Status⁺?

Device Status⁺ (App Store: https://apps.apple.com/us/app/device-status/id6747854290) is a comprehensive device monitoring tool developed by Space-Time Transformation Technology Co., Ltd. It requires iOS 17.0 or later and works across iPhone, iPad, Mac (M-series), Apple Vision Pro, and Apple Watch.

The app delivers live stats on:

  • CPU & memory usage
  • Storage breakdown and history
  • Battery health, temperature, and capacity
  • Network upload/download speeds
  • Device uptime / boot time
  • Sensor diagnostics (accelerometer, gyroscope, camera, etc.)
  • And — the feature we're focusing on here — a second clock in a floating window

Most core features are free, with optional in-app purchases (lifetime unlock ~$2.99 or annual ~$0.99) mainly to support the developer. It enjoys a strong 4.9/5 rating from users who appreciate its accuracy, clean interface, and lack of intrusive ads.

The Floating Second Clock Feature

Introduced in version 1.5.1 (August 2025), the app added a floating window that includes both network speed monitoring and a second clock. This overlay displays the current time with live, jumping seconds — perfect for glancing at exact timing without opening the Clock app or adding bulky widgets.

Key highlights of the floating second clock:

  • Real-time HH:MM:SS display with smooth second updates
  • Draggable and resizable floating window (similar to Picture-in-Picture style)
  • Stays on top of any app or home screen
  • Can run alongside the network speed floating window for a dual-info overlay (e.g., "speed + precise time")
  • Extremely low overhead — no noticeable impact on battery or performance
  • All processing is local (on-device), ensuring privacy and minimal latency

While iOS restricts full-second updates in standard widgets or Dynamic Island for battery reasons, the floating window approach bypasses those limitations effectively.

Quick Setup Guide

  1. Download Device Status⁺ for free from the App Store.
  2. Open the app and grant required permissions (background app refresh, etc.).
  3. Navigate to the floating window or tools section (look for "Floating Window" or similar in the menu).
  4. Enable the Second Clock option.
    • Optionally toggle on the network speed floating window at the same time.
  5. Customize position, size, or opacity if available in settings.
  6. Exit to your home screen or any app — the floating second clock now appears as a persistent, movable overlay.

Why Use Device Status⁺ for Second-Level Time?

  • All-in-one convenience: You get seconds display + full device diagnostics (CPU, RAM, battery temp, network speeds, etc.) in the same lightweight app.
  • Persistent visibility: Unlike lock screen widgets (which rarely refresh to seconds) or Dynamic Island (limited support), the floating window is always visible and updates in real time.
  • Free & reliable: Core floating clock functionality is included at no cost; recent updates (up to version 2.0.3 as of March 2026) have improved stability for time/boot displays.
  • Multi-platform: The same app works on iPad and Mac if you need consistent second-precise time across devices.

If you're someone who frequently needs to know the exact second (e.g., developers, traders, athletes, or just perfectionists), this floating second clock in Device Status⁺ is a simple, elegant workaround without cluttering your screen with dedicated clock apps.
