Tactile Clock
APK
This Android app vibrates the current time when the display is locked and you double-click the power button of your device. How it works Double-click the power button. This might take some practice to work reliably. Press slowly and deliberately. If you double-click too fast the system only recognizes a single click and turns the screen on instead. The time vibration is structured as follows: A short vibration stands for the digit 1 and a long one for the digit 5. The 2 is represented by two consecutive short vibrations, the 6 by a long and a short one and so on. The 0 constitutes an exception with two long vibrations. Examples: 00:00 = -- -- 01:18 = . . -... 02:51 = .. - . 10:11 = . -- . . 19:06 = . -.... -. Explanation: The time is processed digit by digit: . = short vibration - = long vibration Leading zeros in the hour and minute fields are omitted. Gaps: To simplify the recognition of the vibration pattern, there exist three kind of gaps with different durations: []: A short gap between vibrations in the same digit [ ]: A medium gap for the separation of two digits within the hour and minute field [ ]: A long gap to split hours and minutes Additional features Keep informed about the current time. The app can vibrate the current time automatically every X minutes or every hour. Play the Greenwich Time Signal at the start of each hour, similar to a radio station. Trigger time vibration with Tasker (see below for details) Decide what to do if you double-click when the display is on. You can choose between a warning vibration and having the time vibrated as well. The app starts automatically after the system reboots. Double-click conflict TactileClock is triggered by clicking the power button twice in quick succession. This may conflict with the 'built-in' double-click action of your Android device. For example, a Google Pixel device will typically launch the camera when the power button is double-clicked; a Samsung device may take a screenshot when the power button is double-clicked. If your device has a 'built-in' action when the power button is double-clicked, there are three options to get TactileClock working. Option 1: Disable the 'built-in' double-click action of your device. Google Pixel: (Settings > System > Gestures > Quickly open camera) Samsung Galaxy: (Settings > Advanced Features > Side Button > Double Press) Other devices may require different settings to disable the double-click action. Once the 'built-in' double-click action has been disabled, double-clicking the power button will trigger the TactileClock action. Option 2: Configure TactileClock to trigger after a long double-click. This will allow the 'built-in' double-click action to co-exist with the TactileClock double-click action. 1. Open TactileClock 2. Swipe left to show the 'Shortcut' screen. 3. Modify the 'Click Interval:'. 3a. Set 'From:' to be 500ms. 3b. Set 'To:' to be 1500ms. The From: and To: values specified above should work, but may need to be adjusted for optimal results on your device. Once configured, a fast double-click will trigger your devices 'built-in' action, while a slow double-click will trigger the TactileClock action. Option 3: Use Tasker to trigger time vibration with custom events Use

GNU Taler is immune against many types of fraud, such as phishing of credit card information or chargeback fraud. In case of loss or theft, only the limited amount of money left in the wallet might be gone.

Tape Measure (Privacy Friendly)
APK
Privacy Friendly Tape Measure can measure the size of objects in pictures based on objects of known sizes (e.g. coins) in the same picture. Just find a coin or other reference object of a known size, put it next to the item you want measured and take a picture. Make sure all objects are in the same level and the picture is taken perpendicularly to it. Now you can mark the reference object in the picture and measure any length or area you want! Privacy Friendly Tape Measure belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Institute of Technology. More information can be found an https://secuso.org/pfa Privacy Friendly Tape Measure can also display rulers or a protractor on the screen. Use this to quickly measure small objects or to cut a pizza in six equal slices. Yum! What makes Privacy Friendly Tape Measure different from other similar apps? 1. Fewer permissions Privacy Friendly Tape Measure uses only the Read External Storage permission. It needs it because most pictures on your phone are located on the SD-card as opposed to the internal phone memory. 2. No advertisement Many other free apps in the Google Play Store dazzle you with annoying advertisements which also shorten battery life.
