Define the problem: 

Before you start building an app, it's important to have a clear understanding of the problem you're trying to solve. What need does your app address? Who are your target users? What are their pain points? By answering these questions, you can ensure that your app is solving a real problem and meeting the needs of your target audience.

Research the competition: 

It's important to research your competition to understand the market landscape and identify opportunities for your app to stand out. Look at existing apps in your category and take note of their strengths and weaknesses. Analyze their user reviews, ratings, and downloads to get an idea of what users are looking for in an app like yours.

Determine the monetisation model: 

Deciding how you plan to monetise your app is an important consideration before starting development. Will your app be free with in-app purchases or subscriptions? Will it be paid? Will it have ads? Understanding your monetisation model will help you plan your app's features and design accordingly.

Define your MVP: 

A minimum viable product (MVP) is the most basic version of your app that still delivers value to users. Defining your MVP will help you focus on the most important features of your app and avoid wasting time and resources on unnecessary features. It will also help you get your app to market faster and test its viability with real users.

Plan for scalability: 

It's important to plan for scalability from the beginning to ensure that your app can handle a large number of users and a high volume of data. Consider the architecture and technology stack you'll use, and make sure that it can easily be scaled up or down as needed.

By considering these key factors before starting a new app project, you'll be better equipped to create a successful app that meets the needs of your users and stands out in the crowded mobile app market.
