While there a dozens of apps to solve one kind of a problem, each of them needs to have a different approach towards it. A unique approach not only makes the app stand out, it can also increase the revenue many folds.

Almost any app has several development stages. Starting from need analysis all the way up to testing and deploying.But of the most crucial and earliest step of these is Design.

An early wire frame to full fledged mock ups, it determines how the user is going to use the app. What all action will stand out to the user? And how will user reach to them. Its like creating a lawn for the user to take a stroll in. If the user’s path gets obstructed, or at any point user feels confused or if the path seems too long, user will quit!

Keeping this in my mind, our development team makes sure to get involved in the design process as well. This not only makes the work go smooth, but also help extract the aim with which the app get designed. So that the developers can understand and keep the same goal in mind while developing apps.

There are many established design laws that we follow to create a more intuitive and appealing user experience. Some of the most important laws are:

1. Hick’s law

According to this law, increase in number of choices for an action will increase the time taken for user to decide logarithmically. Simply put, this means that more the choices, more the time it will take for the user to select one. Hence, we try to cut the number of options/actions that a user can take when present on a screen.

2. Zeigarnik effect

Russian psychologist, Bluma Zeigarnik first studied the phenomenon of why a waiter had better recollection of unpaid orders than that of paid orders. Turns out users tend to remember uncompleted tasks better than completed tasks.
This applies in an app’s user experience (UX) too! For example, by reminding user with a progress bar, we can drive user to complete his/her profile!

3. Von Restorff Effect

Also known as The Isolation Effect, predicts that when many similar objects are present, the one that differs from the rest is most likely to be remembered.
This can be helpful in cases such as highlighting a subscription offer over another, or in other places where user might have options.

4. Serial Position Effect

Users best remember the first and last items in a list. That is, other middle elements are less likely to be remain in memory of users. Because of this, we place key actions either on extreme left or right within elements such as action bar.

5. Miller’s law

According to this law, an average person can only keep 5 to 7 actions in their working memory. If there are any more, chances are user will not focus on it.

Hence we make sure that any point of time in an app, the number of actions that can be taken, never goes beyond 5. This helps user to remain more focussed and spend more time using app than deciding.

There are many minute observations and ways, that enhance the user’s experience in the app. These phenomenons, not only help the users but also increases an app’s user engagement. Which in turn will result to both happy user and happy business!
We keep all this in mind while developing apps to ensure that we get best of both worlds. Contact us now if you have an amazing idea, that you would like to get executed brilliantly.
