Useful add-ons, I just wish you could string multiple tasks of your choice together, for example, zombie walk, flags, and math, and allow for multiple sets of math or other problem-solving tasks. It does have a multi-catchpa, but it is only 2 pre-selected tasks. I also would like a difficulty mode for some tasks, ex. harder math, or more sheep etc.

Hello Thano, the Multi CAPTCHA has two pre-selected tasks, but it is fully configurable. Go to Settings → Alarms → Captcha → Settings, and choose the tasks you wish to have for Multi. For more details, please contact support@urbandroid.org. Thank you.

So far it's been alright, but I would like assistance on the zombie walk, because for whatever reason, when it went off it didn't seem to want to register any movement as "meters traveled" so I was just stuck for an hour trying to turn my alarm off. Also, I think the LUX one is a bit overkill because it only works some of the time. I am using a OnePlus 7 Pro, permissions have been given to the app, and the walk seemed to briefly work. If I resolve my issue, I'll give it a 5 star.

Edit: It was my mistake. Difficulty levels can be set separately. -- There are wide variety of options. However, difficulty level cannot be set for different methods. Let there be light turns into a torture when the difficulty is medium but fun with flags is too easy for first level. You may want to consider setting the difficulty for each method separately.
