I found a successful app, made it 1% different, and now make $12K/month (STOPPR)
Starter Story
Oct 30, 2025
David Attias was working in finance when he discovered an app making $200K/month. He thought the app was genius. So he rebuilt it in a different niche, and five months later, STOPPR is generating $12K/month with zero coding background required. This video breaks down David's full app building playbook.

I
cloned
a
very
successful
app
and
first
month
of
revenue
I
made
5
000
This
is
David
Adias
a
guy
from
France
who
up
until
six
months
ago
had
a
regular
job
That
was
until
he
saw
an
opportunity
that
most
people
would
miss
I
was
really
amazed
by
the
fact
they
were
making
200
000
per
month
after
three
months
He
came
across
a
mobile
app
making
200
000
a
month
but
when
he
used
it
he
thought
to
himself
I
think
I
can
build
something
better
In
a
couple
of
weeks
he
vibe
coded
a
one
for
one
clone
changed
the
colors
switched
the
niche
and
just
six
months
later
he's
gone
from
zero
to
10
000
a
month
I
brought
David
onto
the
channel
to
break
down
his
entire
playbook
In
this
video
we'll
dive
into
the
app
he
cloned
and
how
he
validated
it
was
worth
cloning
how
he
built
his
new
app
in
just
a
month
and
the
key
change
he
decided
to
make
to
it
Lastly
we'll
go
over
the
exact
playbook
he
would
use
if
he
had
to
start
over
today
All
right
this
one
is
going
to
be
fun
Let's
get
into
it
I'm
Pat
Walls
and
this
is
Starter
Story
All
right
David
welcome
to
the
channel
Tell
me
about
who
you
are
what
you
built
and
what's
your
story
My
name
is
David
I
made
an
app
that
makes
12
000
per
month
I
built
that
app
five
months
ago
and
to
fund
the
idea
for
my
app
I
cloned
a
very
successful
app
and
first
month
of
revenue
I
made
5
000
That's
awesome
It
is
something
that
I've
been
hearing
about
recently
taking
proven
English
or
American
apps
and
localizing
them
to
different
countries
I
think
there's
something
there
I'd
like
to
just
know
a
little
bit
more
about
your
app
What
does
it
do
Who
uses
an
app
like
this
and
how
does
it
work
That's
a
mobile
app
for
women
to
stop
their
sugar
cravings
My
customers
are
around
13
years
old
to
25
so
mostly
Gen
Z
women
We
have
a
monthly
subscription
We
have
a
weekly
and
we
have
a
yearly
with
a
trial
as
well
Okay
cool
That's
amazing
I
think
what
you
did
is
really
cool
with
this
app
but
before
we
get
into
that
I
just
want
to
understand
some
of
the
numbers
behind
this
How
many
downloads
How
many
users
How
much
revenue
has
this
made
In
five
months
I
got
60
000
downloads
Paying
customers
it's
around
900
people
and
I've
been
working
mainly
with
French
influencers
because
I
noticed
that
there
was
no
one
in
France
doing
something
to
help
women
by
cutting
completely
processed
sugar
Okay
my
next
question
is
how
do
you
even
get
into
building
mobile
apps
I
understand
you
don't
come
from
a
developer
background
How
do
you
even
find
the
idea
to
do
something
like
this
I
worked
eight
years
as
a
quant
trader
So
basically
I
was
helping
traders
to
figure
out
which
stocks
to
buy
and
then
I
discovered
some
famous
indie
hackers
like
Peter
Lovells
and
Thibaut
from
Outrank
and
Jack
who
made
Postbridge
and
I
got
really
inspired
by
their
story
because
they
were
able
to
generate
a
lot
of
cash
quickly
And
five
months
ago
I
was
watching
a
podcast
on
YouTube
with
three
teenagers
the
founders
of
Twitter
And
after
month
three
I
heard
they
were
making
200
000
per
month
and
I
was
envious
I
was
jealous
and
that's
what
got
me
started
to
start
Stopper
Okay
I
want
to
talk
for
a
second
about
how
David
built
this
app
It
was
a
few
months
ago
and
he
used
Cursor
and
a
few
other
tools
to
clone
the
app
in
about
a
month
But
this
space
is
changing
quickly
and
I
want
to
tell
you
about
a
new
tool
that
makes
it
even
easier
and
faster
to
build
Rocket
Rocket
lets
you
go
from
just
a
few
sentences
to
a
full
stack
app
Just
describe
your
vision
and
in
a
few
minutes
you
will
get
a
complete
functional
app
Backend
integrations
and
production
ready
code
everything
With
Rocket
new
you
can
import
designs
from
Figma
just
like
David
did
and
integrate
with
Stripe
and
Superbase
in
just
a
few
clicks
400
000
users
from
around
the
world
are
building
with
Rocket
Rocket
because
it's
the
simplest
way
to
turn
ideas
into
apps
in
minutes
and
not
months
So
if
you're
ready
to
finally
build
your
idea
faster
than
ever
check
out
Rocket
at
the
first
link
in
the
description
Thank
you
to
Rocket
for
sponsoring
this
video
I
love
what
you
guys
are
building
All
right
let's
get
back
to
the
video
One
of
the
big
reasons
I
wanted
to
bring
you
on
the
channel
you
took
a
proven
app
and
you
sort
of
made
it
1
different
and
now
you
have
a
really
successful
app
So
can
you
tell
me
a
little
bit
more
about
how
you
found
the
idea
idea
and
how
you
decided
to
clone
that
specific
idea
The
way
that
I
found
this
idea
is
from
YouTube
I
saw
those
three
guys
on
YouTube
and
I
was
really
amazed
by
the
fact
they
were
making
200
000
per
month
after
three
months
And
then
when
I
downloaded
the
Twitter
app
I
was
very
pleased
by
their
onboarding
and
I
did
one
exact
copy
of
their
onboarding
because
it
was
so
good
Well
okay
cool
That's
amazing
On
this
topic
of
cloning
you
can
find
an
idea
then
you
can
find
another
niche
to
put
it
in
But
my
question
for
you
is
how
did
you
know
that
this
niche
quitting
sugar
was
an
app
that
was
worth
building
and
something
that
people
would
pay
for
How
did
you
validate
this
Basically
what
I
did
I
went
on
Google
Trends
I
was
looking
for
a
keyword
such
as
stop
sugar
And
because
for
the
past
five
years
the
trend
of
those
keywords
is
basically
going
higher
and
higher
and
higher
And
then
I
checked
for
the
same
keywords
on
TikTok
and
Instagram
and
I
saw
that
there
were
a
ton
of
women
influencers
that
they
were
talking
about
quitting
sugar
about
stopping
sugar
So
I
validated
by
keyword
research
and
by
content
research
on
TikTok
and
Instagram
and
that's
how
I
knew
that
making
an
app
to
stop
sugar
craving
was
potentially
a
great
idea
Okay
amazing
So
you
validate
this
idea
What's
the
next
step
Building
it
Tell
me
about
how
you
actually
built
Stopper
So
my
first
step
was
to
download
Twitter
to
take
some
screenshots
of
each
screen
What
I
wanted
to
see
is
basically
like
how
we
go
from
screen
one
to
screen
two
to
screen
three
So
I
was
prompting
a
cursor
please
make
the
same
screen
with
the
same
visual
elements
with
the
same
color
with
the
same
image
In
two
weeks
and
a
half
I
did
one
full
copy
of
Twitter
And
then
to
submit
the
first
version
of
the
app
and
to
get
the
approval
from
Apple
that
took
me
one
week
Cool
I
think
anyone
watching
this
right
now
is
hopefully
getting
excited
about
potentially
doing
the
same
So
my
next
question
for
you
is
if
you
were
to
do
this
again
to
start
over
from
scratch
what
would
be
your
playbook
to
clone
a
successful
app
from
the
App
Store
in
2025
The
first
step
that
would
be
to
find
a
very
successful
app
to
check
basically
if
it's
for
a
specific
niche
and
if
that
app
markets
for
specific
regions
and
countries
To
confirm
the
revenue
you
have
to
go
to
SensorTower
to
have
a
sense
of
what
the
app
is
making
as
a
monthly
recurring
revenue
Step
two
you
want
to
research
on
TikTok
and
Google
Trends
if
it's
a
niche
worth
building
Step
three
that
would
be
building
the
design
So
use
a
Figma
plugin
to
import
all
those
JPEG
screenshots
in
Figma
You're
going
to
see
some
discrepancies
there
and
there
but
for
80
of
all
the
screens
that's
near
perfect
There
are
some
websites
like
ScreenDesign
com
and
Mobin
com
So
for
example
you
will
go
there
search
for
Twitter
You
can
download
all
the
screenshots
from
a
given
app
with
one
click
Step
four
I
think
for
most
apps
that's
not
needed
but
if
you
need
some
backend
the
easiest
that's
Firebase
Because
with
Firebase
that
manages
the
connection
with
Google
that
manages
the
connection
with
email
password
and
with
the
Apple
sign
in
as
well
Right
now
like
with
Figma
MCP
you
can
connect
your
Figma
MCP
to
a
cursor
cursor
Before
it
took
me
like
one
month
to
do
the
MVP
Right
now
like
with
the
Figma
MCP
that
will
probably
take
me
two
weeks
Okay
amazing
Thank
you
for
sharing
that
playbook
It's
crazy
to
see
how
fast
AI
coding
is
getting
better
I
want
to
change
topics
slightly
to
tech
stack
Can
you
break
down
the
full
stack
that
Stopper
is
built
in
What's
it
built
on
To
write
code
I
use
a
cursor
To
track
my
revenue
within
the
app
I
am
using
Revenue
Cat
To
have
some
deeper
analytics
about
what
my
users
are
doing
I
am
using
a
mixed
panel
I
am
using
a
tool
which
is
called
TopYappers
com
which
is
basically
a
SaaS
that
scraps
TikTok
and
Instagram
and
YouTube
To
find
the
exact
profile
that
I
need
of
influencers
that
worked
with
other
apps
before
I
will
add
the
email
that
I
find
from
TopYappers
com
And
then
I
will
feed
that
into
LinkedIn
ai
And
then
I
have
been
using
since
the
last
week
the
ads
on
Menta
and
Spark
Ads
on
TikTok
So
Spark
Ads
is
a
great
way
to
increase
the
number
of
views
you
have
for
current
viral
videos
On
that
same
note
I'm
also
curious
what
are
the
costs
to
run
an
app
like
this
What
do
your
profit
margins
look
like
Can
you
break
that
down
for
me
We
have
the
Ultra
Plan
of
Cursor
which
costs
200
per
month
On
Mixed
Panel
last
month
I
paid
around
100
And
for
the
TikTok
Spark
Ads
what
I've
been
doing
for
the
past
month
cost
me
around
100
per
month
So
after
five
months
my
profit
margin
for
Stopper
is
35
Last
question
that
I
have
for
you
that
we
ask
everyone
who
comes
on
Starter
Story
if
you
could
stand
on
young
David's
shoulders
before
you
started
your
app
found
this
app
cloned
it
built
it
what
would
be
your
advice
for
anyone
watching
this
right
now
The
fastest
way
to
make
some
money
right
now
is
to
do
one
to
one
copy
of
a
very
successful
app
And
when
I
say
one
to
one
copy
I
mean
like
you
copy
each
screen
you
copy
each
word
I
change
black
by
pink
I
replace
ideal
content
by
sugar
and
then
done
Yep
I
mean
I
agree
I
think
it's
totally
okay
to
copy
an
app
And
actually
I
think
that's
the
right
thing
to
do
especially
when
you're
starting
out
The
only
thing
that
I
think
that
you
shouldn't
do
is
don't
copy
the
niche
You
don't
want
to
go
and
take
their
customers
take
everything
they
did
and
put
it
to
a
different
niche
You're
not
taking
their
customers
So
anybody
who's
watching
this
right
now
I
think
this
is
a
great
framework
Thank
you
David
for
coming
on
sharing
everything
For
anyone
watching
right
now
let
us
know
in
the
comments
if
you
enjoyed
David's
story
if
you'd
want
him
to
come
back
and
deep
dive
more
into
this
cloning
playbook
Thank
you
David
for
coming
on
Thank
you
bye
bye
Thank
you
to
David
for
coming
onto
the
channel
Personally
I
love
this
because
he
took
a
successful
app
he
switched
the
niche
changed
the
customer
base
and
took
proven
principles
such
as
onboarding
flows
and
a
bunch
of
other
things
and
basically
cloned
it
into
his
new
app
I
think
that's
super
smart
especially
if
you're
starting
your
first
business
idea
you
want
to
get
to
your
first
10
000
20
000
a
month
What
I
loved
even
more
was
that
he
vibe
coded
this
entire
thing
in
a
couple
weeks
That
is
the
power
of
building
with
AI
You
can
have
an
idea
in
your
head
and
turn
it
into
a
working
app
faster
than
you've
ever
been
able
to
do
before
And
this
is
exactly
what
we
show
you
how
to
do
inside
