I've been loving Trainline app for a long time, and I believe most apps and products should learn from it. I tried to sum up its main qualities in a few slides. Let me know what you think about it! What is the next app you think I should work on?

1. WHY IS THIS APP SO GREAT?

2. 5 YEARS AGO, ANYONE COULD
ALREADY BUY TRAIN TICKETS ON
THE INTERNET.

3. BUT TRAINLINE WON.
HOW?
THEIR PRODUCT IS AWESOME.
PERIOD.

4. USER FIRST
1. THE USER IS HOME
2. LET THE USER KNOW
WHAT'S HAPPENING
3. DON'T MAKE THE USER
THINK

5. 1. THE USER IS HOME
Date is filled in
Only what the user
needs. Less is more.
Name is filled in: your
parameters are
saved.

6. 2. WHERE AM I?
After a few
seconds, the
loading screen
is updated.
The user knows
it isn't frozen.

7. 3. DON'T MAKE ME THINK
All previous searches are
filled. No need to type the
same destination again
and again.

8. SMART
PRODUCT
1. SEGMENT USERS
2. UNDERSTAND PAINS
3. SHOW THE USER WHAT
HE IS LOOKING FOR

9. 1. SEGMENT USERS
All users don't
behave the same
way. Segment users
depending on their
behaviours, and offer
different results
depending on their
segment.

10. 2. UNDERSTAND PAINS
Users usually look for
cheapest trips. The
cheapest is highlighted,
so that the user doesn't
have to check
everything.

11. 3. SHOW ME ALL
Not anymore: 1-click
hour pick.
For ages, 2 clicks
were necessary to
pick an hour.
