How much does it cost to design the ui of an APP

Nowadays, many enterprises want to have their own

mobile APPs

, but the most puzzling question for business owners is: How much does it cost to develop a mobile app?

to put it simply, depending on the demand and quality of the mobile APP, the price is generally around several thousand to several hundred thousand, and the higher-end price is higher.

Today, we will analyze this problem in detail. Please read on.

1. APP development styles are divided into fixed models and customized models, both of which have different prices.

Fixed models refer to the direct application of existing and ready-made APP fixed templates. The quotation is fixed, and the required functions are also fixed. The disadvantage is that customers can't get

source code, and they can't customize it according to the needs of enterprises. Because the source code is encapsulated, if enterprises want to upgrade their functions or systems in the future,

the development time of fixed-type APP is short, which can be completed in about 2-3 days, and the cost is between several thousand and tens of thousands.

customized payment: customized payment refers to all the functions of the APP are redeveloped, and the process is complicated, which requires the cooperation of artists, planners, APP development (foreground/client/mobile phone), background programmers, etc. A large and complex APP even needs a team of dozens of people.

because the function and design of the APP are customized, the price will be higher. The development time of customized models is directly proportional to the development price, and the development time is long, which can only be completed in two or three months or even an indefinite period, and the cost is about tens of thousands or even hundreds of thousands.

therefore, to know how much it costs to develop a mobile APP, the business owner must first inform the APP development company of the detailed requirements and functions of the APP, and the development company can quote a reasonable price.

second, different mobile APP platforms have different production costs

there are two popular mobile APP production platforms in the market, which generally include two systems:

Android

(Android) and Apple (IOS).

Generally speaking, it is more expensive to make mobile APP software for Apple than for Android platform, because

Apple

s closeness to Apple platform and the difficulty of developing mobile APP language Objective-C make it more difficult for APP developers to develop mobile APP for Apple system.

third, the production cost of the APP includes the salaries of the participants.

In general, the development of an APP requires

a product manager

, a client engineer

a back-end engineer

and a UI designer, which is a relatively streamlined configuration for making mobile APP APPlications, so the salaries of these participants are also included in the production cost of the app. The monthly salary of these staff members may add up to more than 4, to 5, yuan.

IV. Location of APP Development Company

It should be noted that the same strength of APP Development Company will also lead to higher cost of APP in different cities.

In the past few years when I worked in a startup company, a lot of work involved visual design, but general companies are not so detailed. In my mind, it can be divided into three types:

1. Graphic designers: limited to 2d advertising design, such as business cards, posters, brochures, single pages, etc., the UI made is very low in enforceability, and many of them contradict the native system, which will make engineers have a headache. There is no specification at all.

2.UI designer: Limited to the design of software UI, it is not very difficult for ordinary engineers to get the design documents and execute them, but the plane they made is not creative. From a technical point of view, it is very difficult to make people shine or add marketing ideas. There is no specification at all.

3. Visual designer: He has a good aesthetic concept, a masterpiece of graphic design, and has his own unique insights and experiences for the design of different places and different functions; Have 3D design experience, generally have home and architectural design experience; The software UI and UE of different systems have been studied, and the functional flow of different functional applications has been planned to make the UI not only beautiful but also easy to use. There is a standard document for each company or program.

However, I have encountered the first kind, and I can't afford the second and third kinds. The plane pressure is very heavy, which leads to more resignations. When I handed over the work, I came to talk to him again. I always thought that I should publish a document and get started immediately after reading it. Only now do I know that the original document called Visual Design Specification

indicates the version to be used, the operating system to be designed, and the instructions to be given during development

1. Directs the division of labor and cooperation

2. Avoid duplication of work

3. Visually unify and add extra points to the image

4. Make the thinking clearer and the work more efficient

Visual designers, graphic designers, interaction designers and product managers.

Common component style: unify the styles of components that can be used in the whole UI design, such as dialog boxes, prompt boxes, confirmation information boxes, etc.

Component styles in different states: Component styles in different states are generally the same. The actual effect shall prevail according to the usage scene

spacing: spacing in the frame, spacing between elements

Picture specification: different pages, positions, sizes and colors of pictures, and other parameter requirements

Different applicable versions: tablet, mobile phone, computer and other versions

Integral frame decoration: fixing the whole frame and filling it as a template. Help to control the overall style

different levels of sub-page styles: the design of different sub-interfaces can be completely put to the next designer. Restrictions can also be made if necessary

Step 1: Determine clear flow and ideas

Step 2:

Adapt dimensions: different systems of android and ios, different devices _ tables or structural drawings

Please refer to specifications such as _ndroid dimensions

It should be noted that:

ANDOID should cut the drawings, and cut the icons and picture elements into hdpi and HDPI. Package in three folders

To cut the picture for p>ios, cut the icons and picture elements into @ 2x and @ 3x, and package them in two folders

Step 3:

Confirm that the theme color and element color are set as theme colors in the unified default color scheme of appstyle system

In other elements, such as dividing line color, card shadow color depth, important color text depth and so on.

Font and font size of characters in different places and uses

Step 5:

Icons

Uniform size, notes for special uses, please attach

Step 6:

Buttons

Button styles and styles and sizes in different states

Floating buttons 56dp, Ordinary button 48dp

Step 7:

Common * * * controls

For example, dialog box

Step 8:

Module

Determine the style of a module

Step 9:

Layout

Determine the general layout style

You can't cover all the specifications at once, but you can continue. How to make an app page with UI design software

The first point: Understand the mentality of your target customer group

1. Target customers who do micro-tasks (such as watching news, listening to songs, watching movies and chatting about gossip anytime and anywhere):

This kind of solution is to design an app that is small and accurate, not big and comprehensive. The more comprehensive the functional application, it can only represent that the application is mediocre in all aspects

2. The target customers who like to use it as a tool, such as finding maps, watching the weather and checking data.

this kind of solution is that we try our best to meet the situational needs of users. Be extreme and simple.

3, boring customer base, used to kill time: no demand, aimless

This kind of solution is to show what users are interested in as much as possible and help customers kill time.

second point: the production and design discussion of the APP prototype

this link is essential. It is necessary to draw a prototype seriously according to the design requirements.

commonly used tools of APP prototype drawing: mobile APP prototype design artifacts such as POP, axure, Foreui, etc.

The third point: the key points of APP visual design and design

(1) Generally speaking, the design section includes APP startup page design, APP interface design size specification, app icon design, etc.

Generally speaking, the mobile phone screen is laid out from top to bottom, and important information will be placed at the top. However, in operation, most people hold their mobile phones with one hand, and common operations should be placed at the bottom of the interface.

another principle is that the minimum touch unit is generally 44 pixels. If it is smaller, your thumb is difficult to touch, or it is easy to cause misoperation. At the same time, don't make the interface too crowded.

Therefore, designers must design by subtraction, which takes time to think and simplify elements.

you must remember: (1) hidden design or subtraction design; (2) partition or classification; (3) help users make decisions; (4) improve interactive and innovative design; (5) make people feel refreshed and novel; (6) immerse yourself in emotion in design and grasp users' psychology. (Talk about how to carry out product design and emotional product design)

A master once said, "The real minimalist design is: the work must be continuously simplified, changed again and again until the design is finally formed."

in p>214, the design style of APP tended to be flat and carded. Cards and flattening will be the trend of mobile app design! It is believed that card design does have both advantages of "imitation" and "minimalism"!

fourth point: APP interface design process

(1). When designing the APP interface, learn to seek inspiration from excellent APP interface design works. The former masters of art did a lot of design with a small amount of resources.

(2) It's helpful to have a rest after work. Everything about flat and simple design is related to the differences in details. Therefore, it is better to take a short break and then go back to work with a new vision than to meditate for a long time (p>(3). It is also helpful to compare various formats side by side. Even if it takes 2 minutes to move a line down by 5 pixels and save it separately, you can quickly distinguish between good and bad by comparing the two layouts.

(4). Because the relative proportion of physical display is very important, it is necessary to test on different target devices as early as possible.

(5) Keep asking yourself "Do you really need it?" . When supporting the project, find some clever ways, for example, adding some interesting elements and styles will make it easy and attractive,

but we must always pay attention to eliminating unnecessary elements and constantly streamlining. It's always hard to get rid of what you've worked so hard for, but the revision process must be picky.

fifth point: APP interface design test and preview correction

after the design is completed, we can import the design into the mobile phone for testing or correction. Previously released online testing tool: the method of quickly previewing the rendering of APP interface design on the mobile terminal. Finally, a good APP interface design work must be continuously upgraded and iterated. Generally, the appui/ue prototype is completed with axure, and then it is handed over to the design and front-end to complete high fidelity. I really don't know what software it is.
