- I flat out love the idea. I have a two year old and for me, the biggest thing that I've noticed about parenting is that it's made working out harder. I love food, so needless to say, I've watched my level of fitness steadily decline. This is very bad for me. An app like this would force me to get up and be active because frankly, the sound is worse than a pissed off toddler.
- The sound is worse than a pissed off toddler. My girlfriend said it sounds like a nuclear bomb siren. The sound is bad enough that it would motivate me to do pushups, just to get it to turn off. But, it's in a frequency range that causes lots of people problems. If you choose to keep developing, I'd suggest that having the ability to change/install a custom sound would be a great place to start.
- The pushup detection was poor. Either that, or either my form sucks or we have different definitions of what a pushup is. I did 10 pushups and it registered one and to shut down the infernal alarm, I ended up doing the 'raise the roof' motion. Oddly, the 'raise the roof' motion registered as a pushup every single time. I'm a nerdy 40 year old, so I should likely never do the 'raise the roof' motion. It's arguably even more personally limiting than air drumming along to Led Zeppelin (which is, incidentally, a wonderful workout though when you become known as 'the guy who drums at work', you'd be surprised how few people invite you out for lunch). :)
- You could be onto something amazing. Getting someone into the habit of dropping and doing pushups a few times a day would transform lives. I would pay for it if it checked my form and counted proper pushups for me. Though, it didn't seem to register my pushups, so maybe it does check my form.
Nice work and congratulations on front paging HN! I've got a lot of respect for what you've done and you should feel proud of what you have accomplished. I would be incredibly proud if I were in your shoes.
