在遊戲的世界,一支 App 能夠有 40% 的次日留存率、20% 的 7 日留存,與 10% 的 30 日留存,就已經是水準以上。如果是工具類的 App,留存率還要更低。如何讓一個用戶從下載到長期使用,這中間有太多需要琢磨的功課。

Excited for the launch of +Secret, a new anonymous social app from my ex-Google+ colleagues +Chrys Bader and +David Byttow. I've been using it for months and think they've totally nailed something missing from the social app space. Get it for iOS: https://www.secret.ly/download

Design is hard

As an Android user, I appreciate when applications closely follow the Android design guidelines.

However, there's one tiny bit of the guidelines that keeps surprising me, and that's the overflow menu on the bottom action bar (whether a plain split action bar or a contextual action bar). That pattern is used so rarely that I got very strongly used to the overflow menu being on the top-right.

Sadly, as much as I can feel that something isn't quite right for me, I don't know what would be really right.

-The bottom bar is a great way to display more icons than the top bar would hold, since it's guaranteed to hold at least 5 icons, so it can't go away.

-Generally speaking, spreading the actionable icons over both bars makes them hard to scan at a glance, to the point where that's impractical.

-I wonder if leaving the overflow menu on the top bar while the other icons go to the bottom bar would work. Being somewhat isolated and in a very constant position, it's conceivable that the user might be able to "see" it even while scanning the bottom bar. However, that still has drawbacks: a user scanning the top bar would think that there are no actions beyond the ones in the overflow menu, and a user scanning the bottom bar start-to-end would not land on the overflow menu as the last item for actions beyond the ones already shown as icons.

Following the rules is hard. Breaking them is sometimes even harder.

As usual, this is my personal opinion, not my past, present (or future) employer's.
