Make the offer easy to explain

"A simple budget tracker. It works offline. Pay once. Your data stays on your phone."

One payment

Works offline

Simple to use

Data stays private

Keep the first version small

No user accounts

Data stays on the phone

Low running costs

Quicker to ship

A smaller system is easier to build, explain, and maintain.

Find your first users before launch

I already had an audience from teaching, speaking, and sharing my work.

Share useful work

Build trust

Show the app

Ask for the sale

An audience helps. The app still has to be worth paying for.

Let users guide what comes next

A user asks

Others agree

I build it

Users respond

The Facebook group became my support channel and product backlog.

Expand when demand is clear

I added Android after people asked for it.

900people joined the beta waitlist

~25%of later revenue came from Android

I used the same approach for three apps

Tarsi#1 paid Finance

Mayi#1 paid Travel

Kabi#1 paid Health & Fitness

A simple 30-day plan

Week 1: Choose the problem

Pick one user and one job.

Week 2: Build the core flow

Set the price and keep the scope small.

Week 3: Launch to one group

Ask people to pay and watch what they do.

Week 4: Improve one thing

Ship the most common request.

Ship the app. Then listen.

Real use will tell you what to build next.

One app+one price+one group+30 days

The sky is the limit

Filipino builders can build apps for the world.

I hope the next $100K MRR app is built by someone in this room.
