Purpose: As a user, I would like to know how many exercises I have completed and how many are left during the workout.

More details: Show the number that the current exercise corresponds to and total number of workouts, i.e. 4/10 -> completed/remaining.

Acceptance Criteria:

• Current exercise number and number of total exercises displayed during the workout.

Purpose: As a user, I would like to be able to program hiit workouts using a standard set of timings:

1. Sets
2. Reps
3. Rest between reps
4. Rest between sets
5. Warm-up / cool-down

More details: Some more details on the feature/improvement

See for example the screenshot which implements 1-4 above (but not 5).

It makes it very easy to schedule a program and I are directly how long it will take.

Doing this for 6 sets or 5 reps (30 intervals), with 30 second break between each set and 10 second rest between reps, using the current workout feature, is very cumbersome.

Screenshot from outdated Fdroid app: https://github.com/kwantam/batsHIIT

Acceptance Criteria:

It is possible to specify in the interval timer screen:

1. Sets
2. Reps
3. Rest between reps
4. Rest between sets
5. Warm-up / cool-down

Thank you!

Purpose: As a user, I'd like to use this app also for other types of workouts that require sets longer than 120 seconds

More details: For example WOD such as "AMRAP" that could last 10 minutes, cyclette sets many minutes long or "FOR TIME" workouts in which you have to end it by the time given

Acceptance Criteria:

• Use snake_case (lowercase with underscores) for libraries, directories, packages, and source files.
• Start private variable names with underscores.
• Use lowerCamelCase for functions, methods, constants, variables, parameters, and named parameters.
• Use UpperCamelCase for classes, types, extension names, and enums.

The text on the iOS status bar is always white and does not change to black when the background is also white. See screenshots for reference, the text is white no matter the background.

To Reproduce
Steps to reproduce the behavior:

1. With the device set to light mode, open the app.
2. The background of the home screen will be white. The status bar text will also be white, but it should change to black automatically.

Expected behavior
Status bar text should always be readable.

Screenshots
If applicable, add screenshots to help explain your problem.

Device and Operating System (please complete the following information):

• OS: iOS 17

Additional context
Add any other context about the problem here.

Purpose: As a user, I want to easily select the number of seconds for exercise, rest, and half time.

More details: Something like the horizontal version of the number picker.

Acceptance Criteria:

• Horizontal number picker used for exercise, rest, and half time.

Purpose: As a user, I want to be able to select from a variety of sounds with descriptive names.

More details: Some more details on the feature/improvement

From: https://stackoverflow.com/a/56170945/13394227

Acceptance Criteria:

• Sound selection screen drop downs are visually improved.
• Each sound has a readable and descriptive name.

Purpose: As a user, I would like to be able to choose what sound effects play during my workout.

• Soft sound effects mode. Sound effects played are less harsh than the default.
• Vocal mode. Play a voice that starts "Work" and "Rest".
• Class mode. Play longer sound effects for a group exercise class. This ensures the full group hears the audio cue.
• No audio mode.

Allow the user to either select these specific modes, or change each sound effect individually.

Acceptance Criteria:

• Additional sound effect options are provided and are configurable.

Test: Create a workout

Scenario outline:

1. Start the app.
2. Select the +.
3. Select add a workout.
4. Use all UI elements to adjust the workout settings on the creation page.
5. Continue.
6. Add exercises.
7. Continue.
8. Use all UI elements to adjust the work and rest times.
9. Continue.
10. Use all UI elements to select audio.
11. Continue.
12. Verify that the created workout appears on the home screen.

1. All number pickers and text inputs work as expected.
2. The workout is available to select from the app's home screen.

Purpose: As a user, I expect audio to sound as the clock shows the 3, 2, 1 second marks.

More details: Currently, the 3, 2, 1 second mark audio is slightly delayed.

Acceptance Criteria:

• Audio sounds as the 3, 2, 1 second marks occur, not after.

Purpose: As a user, I the application to inherit the device them.

More details: ^

Acceptance Criteria:

• Application inherits the device them, i.e. light mode/dark mode.

Purpose: As a user, I would like to create an interval timer or workout with more than 50 work intervals.

More details: Currently, the Number of exercises picker only goes up to 50. Increase this to 100 and verify that no issues are introduced, e.g. performance issues when running a workout with 100 exercises.

Acceptance Criteria:

• Number of exercises picker for both creating a workout and creating an interval is increased to 100 (or less if issues are introduced with the number being as high as 100)
• Verified that the app does not experience performance issues with the new max number of exercises

Describe the bug
Not a user of the application here, but I saw it on the new fresh updates in F-droid (with Izzy's repo) and icon looks a lot smaller than all the other ones. Probably because the icon itself is surrounded by too much empty space compared to its own size. This can somehow be seen on your README in the repo, where the icon would also be benefiting from transparent background, because when you use dark themed GitHub, you see the icon into a very big white square background. The icon's size should be increased compared to the square's size, or the square's size decreased.

Expected behavior
Icon should have a scaling similar to other applications, and a transparent background everywhere.

I don't think screenshots are necessary here, but lemme know if you really need some.

Made a mess of code to get features implemented, now I gotta clean it up.

https://en.wikipedia.org/wiki/Don%27t_repeat_yourself

Purpose: As a user, I would like to be asked for confirmation before a workout is deleted.

More details: Some more details on the feature/improvement

Currently, it is easy to accidentally delete a workout as workouts are immediately deleted upon tapping the delete icon.

Implement something similar to the alert dialog shown here: https://medium.com/multiverse-software/alert-dialog-and-confirmation-dialog-in-flutter-8d8c160f4095

Acceptance Criteria:

• Deletion confirmation screen appears after tapping the delete icon.

Purpose: As a user, I would like to see the next exercise during the rest countdown.

More details: ^

Acceptance Criteria:

• Upcoming exercise is displayed on the rest screen.
• It is clearly conveyed to the user that the exercise is upcoming, and not the current interval as the current interval should be Rest.

Purpose: As a user, I want to be aware of the halfway point while my device's volume is lowered.

More details: Currently, there is only an audio cue at the halfway point of the work interval. There should be a visual cue as well so that the user is aware of the halfway point even when the device's volume is lowered. Some ideas:

• Invert the background and text colors for a second. I.e. the background will become white and the text will become green.
• Animate some sort of partially transparent overlay.
• Flash or animate the seconds on the screen.

Acceptance Criteria:

• Visual cue implemented to show the halfway mark of each work interval.

It is intend to deposit a picture for every exercise?
If the specific exercise is running, the picture can be shown above or below the timer.

It would be very usefully for some practices.

Purpose: As a user, I want to use this app in studying. This requires longer periods of time like 45 minutes study and 5 minutes break

More details: More informations about this here

Purpose: As a user, I want to go back to the view workout screen when all intervals are complete.

More details: ^

Purpose: As a user, I don't want the halftime sound effect to interrupt any other sound effects.

Ideally this will be done by drag and drop as shown here: https://stackoverflow.com/a/71071205/13394227

Acceptance Criteria:

• Timers on the home screen can be rearranged.

Seeing the following error:
