Tranquil Stopwatch is a reliable stopwatch designed for extended use with minimal power consumption. It is particularly well-suited for non-interactive sessions, such as meditation or long periods where you cannot actively interact with your device but still need to track elapsed time and know the current time.

**Key Features:**

- **Power Efficiency**: Optimized for long-duration use, with a black AMOLED-friendly screen and no milliseconds display to minimize power consumption. Please note that this app operates without any background service.
- **Reliability**: Ensures accurate timing without deviations, even during extended periods of use.
- **Simple Operation**: Easily pause, resume, and reset the timer; no additional features like laps.
- **Current Clock Display**: Shows the current time in addition to the stopwatch, perfect for sessions where constant interaction is not possible.
- **No Disruptions**: The app does not interrupt you with advertisements, review requests, or other prompts, ensuring a smooth and distraction-free experience.

WhatsNew:

Added total runtime statistics since installation
Some internal refactoring

Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos.

Download Source Issues

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.

Libraries:

Android Support v4 (Development Framework)
The Android Support Library is not actually a single library, but rather a collection of libraries that can roughly be divided into two groups: compatibility and component libraries. For details, please see Understanding the Android Support Library.
AndroidX Activity (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
AppCompat (Utility)
support newer Android features on older Android versions.
Constraint Layout Library (Utility)
library to reduce the number of nested views needed.
Coordinatorlayout (UI Component)
AndroidX library to position top-level application widgets, such as AppBarLayout and FloatingActionButton.
Androidx Core (Utility)
a static library that you can add to your Android application in order to use APIs that are either not available for older platform versions or utility APIs that aren't a part of the framework APIs.
Drawerlayout (UI Component)
AndroidX library to implement a Material Design drawer widget.
Android Emoji2 Compat (UI Component)
core library to enable emoji compatibility in Kitkat and newer devices to avoid the empty emoji characters.
AndroidX Fragment (UI Component)
AndroidX library to encapsulate part of the user interface or behavior into reusable components.
Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
Navigation (Utility)
a framework for navigating between 'destinations' within an Android application that provides a consistent API whether destinations are implemented as Fragments, Activities, or other components.
Preference (Utility)
a library to build interactive settings screens without needing to interact with device storage or manage the UI.
ProfileInstaller (Utility)
AndroidX library that enables libraries to prepopulate ahead of time compilation traces to be read by ART.
Recyclerview (Utility)
display large sets of data in your UI while minimizing memory usage.
Android Activity Saved State (Utility)
provides the base Activity subclass and the relevant hooks to build a composable structure on top.
Startup (Utility)
AndroidX library to implement a straightforward, performant way to initialize components at app startup.
Android Jetpack VersionedParcelable (Utility)
Provides a stable but relatively compact binary serialization format that can be passed across processes or persisted safely.
AndroidX Widget ViewPager2 (UI Component)
replaces AndroidX ViewPager, addressing most of its predecessor’s pain-points, including right-to-left layout support, vertical orientation, modifiable Fragment collections, etc.
Google Material Design (Utility)
library to help with material design guidelines.
