We have been hacking on this for 2 years and it's finally nearing a state where we are stoked about!
Launched last Aug (2015) to the public. Coming up on our 1 yr anniversary and starting to get some traction.
Two of us have _each_ lost about 70lbs while building the app (the rest of the were already skinny, cheaters!) and so it has not only been very fun, but also very rewarding.
The tech:
Backend on GCE:
- 1 api server
- 1 worker server
- 1 redis server
- Cloud SQL 2nd Gen
- <$160/mo
- Autoscale enabled
- Managed by chef
- Rails & Golang
- features first in ruby
- later are optimized in golang micro services
- Heavy user of NSQ
- platform is largely asynchronous
- Avg external (rails) response time: 20ms
- Avg internal (golang) response time: 1ms
- Avg requests/day: 1.3 million
iOS:
- 90% swift app
- 10% obj-c
- Switched from Core data to Realm, and haven't looked back
Android:
- RxJava based
- Slowly converting to realm from just basic http cache architecture
- 2.5 devs
- 1 pr person
- 1 business person
- ~40,000 users
Get some points, and feel good about your body, you only get one! (for now?)
