Large and medium-sized companies are now developing mobile apps for easy communication with their clients. However, many of those concerned do not know the criteria for making a mobile application of good quality. Have you ever felt this unpleasant sensation that often turns into a little nervousness after launching your app? A good percentage of users uninstall apps because of bugs or an ill-thought-out interface.
You should subject your mobile app to different tests before launching it. These are some of the criteria to consider when creating your mobile app. You should discuss this top app development companies before they develop your app.
Speed and Fluidity: the first criterion for a successful mobile application.
The speed with which the users navigate through the app is very important. Many criteria will influence the speed of navigation. If there is a large number of images to load (e.g., a page with a list of photos), the page will take a longer time to appear, but the overall quality of the programming will play an important role in speeding up the transition.
You can add to the fluidity of the app when you experience general performance problems such as:
- jerking when scrolling a list
- zoom on a page
- animation with too low frame rate (less than 20 frames per second)
Here are some tests to perform when you experience these problems:
- Watching the speed of navigation and taking into account the parameters mentioned above.
- Zooming and moving the interactive elements as quickly as possible to get the best speed.
If the speed is rather jerky/slow, then you should consider optimization. Top mobile app development companies will develop an optimized app for you.
Monitor Your Battery: A poorly optimized application will consume excess energy.
A poorly programmed background patch App will cause a significant energy loss in the long run since the users won’t close most apps but instead, leave them in the background. Paying attention to this criterion is essential.
For example, some applications do not pause. They do not reduce their frame rate (or FPS). This corresponds to the number of images you see in one second. In the cinema, the standard is 24 frames per second to obtain a perfect fluidity. For mobile applications, the goal is much higher (60 frames per second). If you reduce the number when the app is used in the background, it will consume less energy.
On Android, you can watch the percentage of CPU usage (Processor) of the App while running in the background. On iOS, the only possibility is to watch if your battery has a conspicuous consumption or not.
The Size of the Mobile Application: an important factor for users.
Your device will have low storage space if it contains a lot of photos and applications. Downloading an App should not take you all day. Some big companies have seen their download increase significantly by reducing their app size.
The size will depend on the quality of the images of the application and the resolution of the terminal used. An image with a high resolution will be larger than an image with a low resolution. Users take note of the sizes of mobile apps when downloading them and they can compare them with other apps.
Secondly, it is possible that some of the images (backgrounds, buttons, etc.) are not included in the app. The size of an app can increase significantly after installing it. So you should put an effort not to let your app consume much of the memory of the users’ devices.
Maintenance and Scalability: the key to good monitoring.
Often, an application requires a regular update of its content. To remedy this problem, you can externalize the data and the images on a server. This allows the developer to change the content in real time without having to resubmit his product to different stores. The submission process can be particularly long and painful. It takes a week for validation by Apple and four days for an update. The validation shouldn’t be a problem if you contract your app development projects to top app development companies.
The display must adapt to different formats of phones/tablets. Outsourcing the images on a server allows loading only the content suited to the resolution of the device.
The advantages of this process are:
- Better loading speed
- Lighter application
Bugs: the obsession of any user.
Bugs haunt both developers during the test phase and the users’ experience.
They are present in the majority of mobile applications since it is difficult and sometimes impossible to predict all the different areas where the bug can occur.
Testing is an important moment in the creation of an App. The quality of a mobile application will depend on how long the creator has to fix the bugs. It’s a long job that can take several weeks.
Here is a small list of tests to detect major bugs:
- Check the application in Offline mode. Is navigation always possible?
- For music and video, put the app in the background and then open it again. Observe if you notice any change.
- Modify a parameter of the application and restart it. Carefully study the functionalities of the app if there is any change?
A Good Display Quality: a criterion to attract the user
It may be obvious, but many developers neglect this aspect regularly. If an image is not at the correct resolution, it will be pixelated, and you will see tiny squares that degrade the image. Different mobile devices like tablets and smartphones often have different display resolutions. Graphic designers will have to create images for each resolution (or almost) to obtain a perfect display quality. This necessarily has its cost, but a good application will have clear images.
Watch out for image distortion. Images can be stretched in width or height. If you have multiple mobile devices, you should check the display quality. A good application should not have this type of anomaly.
You should ensure that you discuss the features you want on the app with top app development companies before asking them to develop the app.
