Most industry-leading voice-over-internet-protocol (VoIP) platforms come with mobile and desktop apps, but these apps aren’t all created equal. Businesses that plan to use mobile VoIP apps extensively will want to make sure they choose a service with robust, user-friendly mobile apps that work for both iOS and Android devices. We analyzed the best apps on the market and evaluated them based on price, features, and ease of use.
We then narrowed the list down to our favorite six before picking an overall winner, which are:
- RingCentral: Best overall for businesses wanting a robust, reliable, all-in-one VoIP app. Plans start at $19.99 per user, per month.

How We Evaluated Small Business VoIP Apps
Most VoIP business phone services have mobile apps, but sometimes they can have clunky, difficult-to-use interfaces that make them impractical. Other times, mobile apps are limited to premium tiers, requiring businesses to pay extra to get mobile device access. The best VoIP apps are easy to use and provide users with advanced telephony features—plus, they’re affordable for small businesses.
While all the services on our list have more-than-capable mobile apps, RingCentral has a slight edge thanks to its feature-rich platform and unified communications functionality. RingCentral’s mobile app is robust and easy to use for employees and end-users alike, making it our top pick for small business VoIP apps.
To help you avoid the letdowns, we found the best-of-the-best VoIP apps by looking at a few important criteria. Click through the tabs in the box below to see our full evaluation criteria for business VoIP apps.
20% of Overall Score
The best VoIP apps should have budget-friendly plans for small businesses. Pricing should scale depending on the number of users you have on the plan. Entry-level plans should provide enough functionality for users to effectively use the platform, and mobile apps shouldn’t be gated behind expensive premium plans.
25% of Overall Score
In order to be a viable system for most small business users, VoIP apps need to be available on today’s most popular mobile platforms: iOS and Android. We also looked for basic core functionality such as voicemail, automated attendants, and a desktop app for office use. Since these are things any decent VoIP system should have, we gave this less weight than other facets.
30% of Overall Score
Small businesses need simple, easy-to-use mobile apps—but not too simple. The best VoIP apps pack their software with advanced features to give users complete control over their phone calls, from start to finish. It’s in this category that we start to see the good solutions separated from the truly great ones.
25% of Overall Score
Not every comparison is apples to apples, and sometimes we just have to go with our gut instinct. Our expert score is given based on the apps’ look and feel, platform popularity, user reviews, and our personal experiences using the services.
