I've been using Alarm Clock xtreme for many years. It allows me to set up a configurable number and difficulty of math problems to snooze or turn off the alarm and set up my own mp3s as alarm sounds. I stopped updating the app some time ago because the new owner started adding questionable adware/spywareish extensions. Although I don't believe these operate in the paid version I use, they're still in the code, and that makes me uncomfortable. I prefer something cleaner.

Android Marshmallow also includes a deep sleep feature called doze that forced all alarm apps on Android to change their code. So long story short, I need a new alarm with those two features I mentioned. What are you guys using?

I use just the normal clock xD Just use a cat vomiting as the alarm, and you'll be up in no time!

I think if I heard the sound of a cat vomiting first thing in the morning, I might be inclined to pull the covers over my head and wait for the sweet release of death. As bad omens go, that one has to be pretty far up there.

You could make your own alarm clock app. Android isnt to hard to program for and its something you could do for yourself. also mean that you only have to target one device and that would be yours. You also wont have to worry about spyware or other questionable addons.

I actually conceived of a tasker based alarm once and started designing it after they added scenes (gui elements), but alarm clock xtreme worked so well I was never very motivated to work on it. On the upside, I could add stuff like random trivia questions if I could find a large database to plug into it, and make it easier to set up prealarms (like gentle alarm does, I do this by just having a second alarm 15 minutes before my first, but when I change one, I have to manually change the other).

It's probably not something I'm going to do right now and if I ever do, I'm now more likely to use unity or perhaps xamarin/visual studio instead, but it's a good idea for someday.

Solving mind games when you wake up...just no.

i just tell siri to set the alarm.. the default sound is horrible and jarring so it wakes me up right away lol.

I use my Fitness Band - Microsoft Band first generation. The good is it vibrates on my wrist so the alarm doesn't wake anyone else up like the dogs you know they need their sleep. You can still snooze. Plus is tracks my sleep which is really confirmation for what most people already know you didn't get enough sleep.

Looks neat I just worry what chants might do? Worship Satan or put a curse on me? I also don't feel whales are soothing.

- Nature sound lullabies (whales, storm, sea, chants..) with binaural tones for fast fall asleep

Hmm this could be funny would be great if it turned the camera on too during detection. Oh I'm going to have to try this after a night of drinking.

- Sleep talk recording, snoring detection and anti-snoring

- snoring statistics

This is just Cruel before Coffee

- Never oversleep again with CAPTCHA wake up verification (Math, Sheep counting, Phone shaking, Bathroom QR code or NFC tag)

Hoping the next fitness band had oxygen screening. Great idea.

- Oximetric Sleep Apnea pre-screening

6am comes.

Last night I went through a bunch of alarm apps I remembered and checked the most recent reviews to see about marshmallow compatibility. The results were scary. Even apps that had been recently updated had lots of complaints about alarms not going off consistently.

The one you, BH, posted looks a lot better than those and even has a few nice features I hadn't thought of, at least no complaints about alarms not going off, though it does look like they have some other issues from the reviews.

I think I'll delay upgrading to Marshmallow for a while longer. Maybe a long while.

I just use the native app for my android it works quite well uses all the ring tones and has multiple alarms.
