You're creating a mobile app for your business. What tools should you use to make it successful?

I always prefer deep study firstly on a project. every point clear of the basic idea, meeting with all members and discussing all key points. Then start working on the design on Figma and UI/UX. The developing phase starts. We very speedily solved the one point-by-point. the testing phase starts and solves all bugs and rechecks the client's requirements. Then changes and finally solves the problem.

Design tools plays vitol role especially their uses If you're developer and you don't know how to figma works this gona take alot of time instead you should have complete understanding of tools that how plugins of figma can be use to reduce efforts.

Usually there are a few meetings between the team, the stakeholders and the designers to define the overall features. Apps like Figma, Sketch, Adobe XD or other proprietary tools can be used by designers to simulate the UI and real life interactions between screens. They also saves developers' time by providing assets and dimensions.

I always prefer deep planning before getting started on a project, it's compulsory to get everything clear to every team member before the progress is started which results in better understanding for every individual working on the project, design isn't only related to graphic design or UI/UX, it's a deep planning to the solution of the problem.

Before starting development choosing your tech stack according to client needs and budget and the kind of features demanding in app is one of the important step in development else a project will be doomed with no end and will lots of missing features.

Here's where the building gets built! Depending on the specific platform, you may use Android Studio, Xcode or other IDE to code your solution. Not only that, BTW. Tools like GIT, GitHub or Bitbucket allows the team to collaborate, review PRs, comment on the code and manage code branches. You need to understand and use collaboration tools, like Slack, Teams, and Agile / Issue tracking tools, like Jira, Confluence or similar for documentation. At some extent, you might need to deal with Jenkins for CI.

For developer perspective only writing a code without knowing how Unit testing, instrumentation testing or ui tests works worth nothing but at the end it totally depends on product worth and client demand over quality instead of time frame.

Tools like Jira, Asana and other Project Development tools allow you to track and log bugs, dev tickets and issues. You can dive into the code to find the problem, but you could also sniff the network traffic with inspection tools, check logs for some weirdness or use tools like Splunk or SQL development to inspect remote databases. A good practice is to regularly write Unit and Integration tests as long as you code or change your features. Espresso, Mockk and Appium makes your life easier while writing tests. With Firebase you can also receive real time stack traces for any environment, also for production!

A smooth distribution of app with a lot less size and performance efficiency along with release guidelines if a developer properly follows the first 3 steps.

Google Play and the App Store are evolving every day. Not only they can help you with every aspect of the release process, they can handle alpha, beta and Friends and Family closed test lists, or specify a percentage of the target population of users that will install a specific update. A lot of attention is put on content rating, geography differences and regulations. It's better if a whole different team is dedicated to curate the store presence, you should never leave developers alone on it!

Marketing of any product plays critical role else if the product targets lets says health and there is zero marketing of product which can be due to lots of reasons one can be financial scenario and the product will be doomed.

Usually, big companies have dedicated teams for promoting and sponsoring the app and its service. You can prefer phisical channels, like boards, or virtual ones, like on social medias. Normally, a developer don't take parts on those activities. Anyway, campaigns of early testing could be organized, so selected portions of the user base can try the app before it goes live. It's a good practice to let also developer participate, so they could see the impact of development choices on the final potential users.

Without marketing even a very innovative idea is nothing, if people didn't see, your product didn't exist, good marketing let's your product reach the people who value your product.

What else to consider? Please keep in mind, don't just think about earnings or using the product for a business, I mean yes you'll need funds, but what I mean is that you should keep the user the quality of the product in mind too, and you'll have to make all these things go in parallel.
