This is fascinating. What do deaf people normally do in lieu of alarm clocks?

Bright light ones seemed quite popular in the deaf flats at my university.

Great idea. OP: Why not allow the app to use the camera flash as well? I (am not deaf) would prefer to have it on my desk so it can actually listen rather than under a pillow where I'm more likely to knock it out of reach

This sounds like a lawsuit waiting to happen. I think it's a great idea, but at 2.99 I don't think it's going to be profitable enough to take on the lawsuit risk.

EDIT: Let me preface by saying, the fact that a person could be sued for creating an app that creates a solution where few or none existed is both utterly ridiculous and highly likely. Which is why I think...

...There needs to some kind of legislation/regulation on lawsuits. Perhaps, the plaintiff must pay the legal fees for the defendant upfront, up to a maximum of 5% of the desired damages being sought.

Example: If you want to sue for a $1 million, you have to pay up to $50K in legal fees for the defendant. If you win the case, the defendant's legal fees are tacked onto the damages that he must pay. If you lose the case, you lose all your money.

I think this would discourage many lawsuits from happening. Only those with true merit would be pursued.

My girlfriend is partially deaf in one ear, so sometimes she will oversleep if she is lying on her good ear. A while back I built her an Arduino-powered alarm clock that uses a servo to repeatedly poke her with a foam finger (those big hands you wear at football games). It was a shoddy prototype, but the cool part was it synchronized with her iCal calendar.

So, to answer your question, some [partially] deaf people use a makeshift Arduino robot that is duct taped to the wall next to their bed.

What basis do you have for this statement? 'Sounds like' and 'i don't think' are not very convincing.

Any reliance on an app such as this is going to be at the risk of the user. This is a tool for assistance and is not in anyway a replacement for standard emergency protocol.

Great idea. I just hope this sort of thing isn't over-regulated.

I had a similar thought. Less about the regulation, more about liability.

If I'm deaf and I pay for an app to tell me when an alarm is sounding, I have a certain expectation that it has been rigorously tested and will work without fail. And I'm a software engineer who understands the limitations and failure modes of such applications on non-real-time, commodity kit.

Please be extra careful about how you market this. I absolutely applaud your ingenuity, but I'd feel differently if I found out my elderly, hard of hearing gran was relying on any app on her smartphone to wake her if she left the stove on and went to bed.

I expect a proportion of your customers may be less technical users (or well-meaning relatives) with little understanding of the limitations and risks.

However, it is indeed an interesting idea. There may already be something on the market, but what about developing it into a physical device running on dedicated hardware? Crowd-fund an "alerter badge" or pin or whatever, and budget heavily for testing & verification. You could be onto a winner.

EDIT: Please don't be put off altogether by the comments. It's simply that non-real-time, non-failsafe smartphones aren't built for life-critical applications like this. The idea isn't a bad one - you're just targeting the wrong platform.

Vibrating for it to wake you means you need to keep it close to your body. I wonder what health implications it may have -- In general its really bad to have a cell phone touching your body for prolonged periods of time because of the radiation it emits.

I would really like to see a citation for that!

Aside from being a little warmer, the radiation has no effect on you.

I'm not deaf, and I have virtually no experience building things specifically for those that are, but this seems like a great idea. Nice work!

Thank you! I'm a college student with an early class (so I have to go to bed earlier than most people), and my dorm can be pretty loud, so I often sleep with earplugs. I didn't like the idea of possibly not waking up in a fire, so I made this to cure my paranoia :p I don't know how many people will find it useful, but it seemed like something that should exist.

Great idea for an app! I sleep with earplugs occasionally and I can see myself using your app in that situation. That said, I've been wondering lately if using earplugs often is a healthy thing to do in the long run. I couldn't find any pertinent research about non-professional users.

Edit: phrasing.
