PocketClock

PocketClock lets you check the time discreetly without ever taking your phone out of your pocket or looking at the screen. Simply double-press your chosen volume button, and PocketClock taps out the current time through clear, intuitive vibration patterns while your screen stays off and your audio volume stays unchanged.

Built for moments when looking at a bright screen is distracting or inconvenient, PocketClock lets you feel the time silently during meetings, classes, lectures, or movie theaters, while walking outdoors with your phone in your pocket or bag, or in bed at night without waking your eyes with a bright display. It also provides dependable, eyes-free tactile timekeeping for blind and visually impaired users.


How the Haptic Time Code Works

PocketClock converts the current time into a 12-hour format rounded to the nearest 5 minutes. Every readout has two parts separated by a 0.75-second pause: first the hour, then the minutes.

For the hour vibrations, count by fives and ones. Each long buzz (320 ms) equals 5 hours, and each short tap (90 ms) equals 1 hour. Simply add them together: one long buzz plus two short taps equals 7 o'clock, and two long buzzes plus two short taps equals 12 o'clock.

After the 0.75-second pause, the minute vibrations count by tens and fives. Each long buzz equals 10 minutes (10, 20, 30, 40, or 50), and a short tap at the end adds 5 minutes. Two rapid micro-clicks (30 ms) indicate the exact top of the hour (:00). For example, 3:15 is three short taps, a pause, then one long buzz and one short tap.


Interactive Visualizer and Practice Tools

Learning the vibration code takes less than a minute. The home screen features a live clock and pattern visualizer showing the current time, the nearest 5-minute haptic readout, visual pulse shapes, and a plain-English breakdown of the hour and minute vibrations. Tap the Test Current Time Vibration button to feel the current time while watching each pulse light up in sync on screen, or read the built-in cheat sheet with step-by-step examples for times like 3:15, 7:40, 12:00, and 9:55.


Smart Volume Button Handling

Choose Volume Up, Volume Down, or Either Volume Button as your trigger. When you double-press within 0.5 seconds, PocketClock intercepts the gesture so your volume does not change, while single presses and press-and-hold actions adjust volume normally. PocketClock automatically steps aside during phone calls or when the phone is ringing, works alongside music playback, and uses alarm-grade vibration attributes so it works in silent mode, vibrate-only mode, and Battery Saver mode.


Customizable Settings and Pocket Sensor

Adjust vibration intensity across Low, Medium, and Strong presets with instant sample feedback on supported devices. Enable the option to only work when the phone is off or locked so double-presses never trigger while you are actively using your phone. On devices with an ambient light sensor, enable the darkness filter to only trigger when it is very dark (5 lux or less), complete with a live lux reading in settings so PocketClock only vibrates inside a pocket, bag, or dark room.


Reliable Deep Standby Operation

PocketClock is engineered to respond even after your phone has been locked in your pocket for hours. It combines Accessibility Service hardware key detection, a keep-alive foreground service, screen-off media session routing, and automatic startup after reboot, plus clear setup cards for Accessibility and unrestricted battery settings.


Privacy and Accessibility Disclosure

PocketClock uses the Android Accessibility Service API solely to detect rapid double-presses of your selected hardware volume button while the screen is off or locked and to prevent double-presses from changing your volume. It never reads screen content, never logs keystrokes, has no internet permission, shows no ads, and collects or shares zero user data.
