The Problem

You want to build digital products. But every guide assumes you have a laptop, coding skills, and money to spend.

The Solution

A complete system built and documented in real time — from idea to paying subscribers.

This is not a theoretical guide written by someone who has never shipped a product. I built the True Price Calculator — a subscription pricing tool for Nigerian product sellers — from my Android phone, using only free tools, with no coding skills. This guide documents every step I took, every prompt I used, and every mistake I made.

By the end of this guide you will have the exact system to replicate what I built — or build your own tool for a completely different niche.

The Revenue Potential

What this system can realistically generate in your first 90 days.

These projections are based on conservative subscriber numbers. The True Price Calculator targets Nigerian product sellers — a market of millions with a clear, expensive problem.

Scenario Subscribers Plan Mix Monthly Revenue
Conservative — Month 1 20 subscribers 50% weekly, 50% monthly ₦70,000
Moderate — Month 2 50 subscribers 40% weekly, 60% monthly ₦190,000
Growing — Month 3 100 subscribers 30% weekly, 70% monthly ₦410,000
+ Digital product sales 10 guide sales/month ₦15,000 per guide ₦150,000
Realistic Month 3 Total ₦560,000+

These figures assume consistent promotion using the video marketing strategy in Chapter 9. Results will vary based on effort and audience size.

I was charging ₦8,000 per bag. After using the True Price Calculator I discovered my real cost was ₦9,800. I was losing ₦1,800 on every single sale. I adjusted my price to ₦16,333 and my monthly profit went from zero to over ₦130,000.

Who This Guide Is For

This guide is right for you if:

✓
You are a digital consultant or freelancer who wants to add a recurring revenue product to your income — without building from scratch alone.
✓
You have an idea for a tool that could help a specific niche — but you don't know how to build it or charge for it.
✓
You want to sell digital products but don't know what to create or how to package your knowledge into something people will pay for.
✓
You work with small business clients — in Nigeria or French-speaking Africa — and want to offer them a branded tool as part of your services.
✓
You only have a smartphone and have been told you need a laptop and coding skills to build software. This guide proves that wrong.
Common Questions

Answers before you buy.

Do I need a laptop to follow this guide?
No. Every step in this guide was completed on an Android phone. The tools used — Google AI Studio, GitHub, Vercel, and Flutterwave — all work in a mobile browser. A laptop makes some steps easier but is not required.
Do I need to know how to code?
No coding knowledge is required. You build the app by describing what you want in plain language — Google AI Studio's Gemini AI writes all the code. The guide shows you exactly what to type to get the results you need.
How much does it cost to build the system described in this guide?
The core system is free. Google AI Studio, GitHub, and Vercel all have free tiers that are sufficient for launching. Flutterwave is free to set up and takes a percentage only when you receive payments. The only cost is your time.
Can I build a different type of tool — not a pricing calculator?
Absolutely. The system in this guide applies to any tool-based product. Chapter 1 walks you through how to identify your niche and validate your idea. The prompting, deployment, and monetisation chapters work for any web app.
How is this guide delivered?
You receive instant access to the PDF and DOCX file immediately after payment through Selar. You can download and keep it permanently.
Can I buy and resell this guide?
No. This guide is for personal use only. If you want to teach this system to your own audience, contact us on WhatsApp to discuss a licensing arrangement.
