making your mobile experiences feel lightning-fast 11
not the code, but the experience 12
mobile design requires the ultimate in design & development collaboration

speed matters 15
mobile experiences fill gaps while we wait 16
no one wants to wait while they wait 17

details that need to be designed 23
3 secrets to apps that feel lightning-fast, even on 3G
24
1. perform actions optimistically 2. adaptively pre-load content 3. move
bits when no-one’s watching 25
perform actions optimistically 26
latency is what’ll get ya 27

why it works 40
@thesarahnator 41
@stayintheshade 42
adaptive pre-loading 43
basic version: load content before it’s needed 44
“let’s load all the images in the feed once the
user loads the page” 45
fresh feed 30 photos to load 46

most apps upload here we start uploading here 82
non-optimal engineering solution 83
2 requests, 2 round-trips + latency need to match up
84
but makes uploads feel really, really quick 85
send data/info as soon as part of it’s ready to
go; match up later 86
worth it even if you throw out the data on
cancel 87
why it works 88
where to go from here 89
“it works” isn’t enough 90
