Did you know that over 90% of consumers tend to avoid companies with negative reviews? Today’s customers are indeed more demanding of businesses than ever. Review apps like Yelp or TripAdvisor greatly influence their decisions to interact with this or that organization.
According to Globe Newswire, 95% of consumers read Internet reviews before buying a product. Other stats suggest that 79% of customers trust online reviews as much as recommendations from their friends or relatives.
In such circumstances, building a review application is a particularly relevant idea. This article will comprehensively look at creating such apps with all the necessary features, tech stack, design tips, and cost breakdown.
Softermii has an extensive portfolio of developing review apps, and the company will share practical advice from its own experience. Moreover, we create such software for various industries, and our products DogVacay and MedRealtime are proof of this.
Now, let’s get straight to the point.
Review App vs. Review Website: What to Create First?
Perhaps you are a startup that plans to build a review app. Or a website? Let’s find out where it’s best to allocate your company’s time and resources.
First, modern users increasingly choose a smartphone over a desktop or laptop. And now, more than 83% of the world’s population has smartphones. It is not surprising since such a device helps to perform many tasks on the go.
Second, people have spent about 90% of their mobile time using various apps in 2021. Even if you opt for creating a website, more than half of its traffic will still come from mobile devices. More precisely, it is almost 59%, according to the latest Statista data.
As for review apps or websites, 80% of consumers use mobile phones to read reviews about this or that business.
If you still have doubts about what to start from, a mobile app or a website, here are some more arguments to support application development:
- Mobile apps can offer a more personalized experience for users, which is especially critical for review applications.
- Apps can run faster than websites.
- You have more freedom in your mobile application’s design.
Features for Your Review App like Yelp
To create a review app, we advise you to be inspired by successful examples available on the market. There you can get ideas for the functionality of your product.
So let’s see what fundamental features are needed to create an app like Yelp.
1. Reviews and Ratings
Of course, a review app cannot exist without a corresponding feature of reviews and ratings. You can implement such functionality by allowing users to leave text messages, photos, and video reviews and rate the products or services.
2. Sign-In, Sign-Up, and Social Login
It’s also a good idea to allow your users to join your review platform. For this, you need to integrate sign-in and sign-up features and take care of social login. The latter functionality allows users to log into your app via social media accounts.
3. User Accounts
Since you have added the possibility of registration and authorization in your application, you cannot do without user accounts. Let users be able to make bookmarks, view their reviews, and have access to the newsfeed, friends, etc., in their profile.
4. Business Pages
Business pages are similar to user accounts but with a professional direction. These are profiles of companies on which users will read and leave reviews and provide ratings. Also, give businesses the option to add a short description of their company, photos, and videos, indicate business hours, and other relevant information.
5. Analytics and Activity Tracking
This feature applies to professional accounts of your review app. Thanks to this functionality, businesses can check the activity on their page and conduct analytics. As a result, companies will be able to improve interaction with customers.
6. Location-Based Search and Filters
It would be nice to allow users to find reviews of places nearby. The filter function, in turn, will enable them to choose locations according to the desired category, such as restaurants, hair salons, shopping spots, auto repair services, etc.
The check-in function is an opportunity for users to confirm that they have visited a particular place. This feature will also display the places a person has visited other users.
The notification feature is integral to almost any mobile app. Thanks to it, you can inform users about any updates on the platform.
9. Photo and Video Uploading
This feature is helpful in a review app development. It’s necessary to post detailed reviews illustrated with photos or videos. It is also required for setting a personal profile avatar or adding content to a business page.
Additional Features for a Review Application
Now you roughly understand how to make an app like Yelp if we talk about basic features. However, this is just the beginning of your journey. You can improve your app with extra functions and engage your audience.
The newsfeed is an additional feature with which you can enrich your platform. It will make your application closer to social networks, where users can view a chronological list of updates and previous actions.
2. Reputation System
The reputation system is a feature that will show businesses’ overall success and credibility. Thanks to this functionality, users can more easily choose to favor one or another company.
3. Admin Panel
The admin panel is a feature you must integrate with the content management system or CMS. This function allows you to edit content and manage users and services.
Features for a Review App Depending on the Niche
In addition to the basic and additional features you need, consider your niche when making a web app like Yelp. Depending on the industry in which your platform will operate, you may require to integrate other specific functionality.
Therefore, before starting review app development, determine your niche and conduct thorough research. Here are some industry-specific features:
1. Booking Management
Such a feature is integral for review apps in the travel industry. It can be from booking tickets for various transport types to reserving tables in a restaurant or securing a hotel room. For example, such functionality is available on TripAdvisor and Expedia.
2. Property Management
The property management feature is also available in travel apps or hospitality software. It can also be part of real estate application development. For example, the Booking.com platform has this function on board.
3. Appointment Scheduling
This feature is especially relevant in the healthcare field. For example, it can be an application to search for doctors by reviews and ratings with the ability to schedule an appointment with a specialist. We implemented such functionality in our MedRealtime product.
How to Create an Effective Moderation System in a Review App
The moderation system is, without exaggeration, the most critical feature for the success of your review app. This functionality uses AI and keyword filters to validate user-generated content against your platform’s requirements. Of course, such a system works most effectively with live moderators.
Automated content moderation will help you fight fake reviews, spam, unacceptable content, or simply content that does not comply with the rules of your application. Such a system can review text, photos, and videos.
There are three types of content moderation that you can leverage during review app development:
- Pre-moderation. It’s a review of content before publication.
- Post-moderation. It’s a review of content after publication.
- Reactive moderation. It’s when users themselves act as content moderators, sending complaints, etc.
The moderation system is a great way to let users post real-time reviews and increase trust in your service.
You have two ways to build your moderation system: by creating keyword filters or by applying machine learning tools.
As for keyword filters, here’s what you need to do:
- Build filters for regularized expressions, i.e., common inappropriate phrases or words.
- Create a moderation interface.
Machine learning technology is a bit more complicated, but you can use it as follows:
- Determine what content you need to moderate.
- Create test sets with correct labels.
- Train ML models.
- Deploy ML models.
- Create a moderation interface.
Tech Stack: Architecture for an App like Yelp
To create an app like Yelp, you need a so-called LAMP stack. This acronym stands for Linux, Apache, MySQL, and PHP. Together, these are tools that allow you to create high-performance web apps.
In addition to the LAMP stack, the Yelp app uses ElasticSearch for search, HAProxy for platform load balancing, and Facebook Scribe for logging. This software uses MySQL as a database.
Here’s each element of Yelp’s tech stack:
- Programming language: Python
- Hosting: Amazon EC2
- Operating system: Ubuntu
- Load balancing: HAProxy
- Search: Elastic Search
- Version control: Git
- Logging: Scribe
- API framework: Swagger
- Web framework: Pyramid
These are just the suggested technologies, thanks to which you will be able to create an app for customer reviews like Yelp. Yet, you can also apply alternatives. For example, in addition to Python, we can use Node JS. That is, the tech stack will differ according to the requirements of each product.
Some UI/UX Design Tips for a Review App
You are already a few steps closer to review app development with the selected features and tech stack. Another thing you should pay close attention to is UI/UX design. Designing an app like Yelp requires minding the following tips:
Remember that the navigation of your application should be intuitive. To do this, you must clearly label all buttons and menu categories. It is also crucial to consider that app navigation should be easily accessible and never hidden.
Remove all the clutter from your user interface. Make sure your app’s UI is minimalistic and simple. An application with reviews already involves a lot of information; if it is loaded with other not-so-relevant elements, your users will be perplexed.
OS Design Guidelines
It is essential to consider an operating system for which you are creating an application design: iOS or Android. Depending on the platform, you will need to follow the design guidelines for each system.
Chances are that you’re building an app that users with different demographics and abilities will review. That is why taking care of your product’s accessibility is critical. It should be suitable for older people, people with impairments or disabilities, etc.
