RingCentral’s desktop and mobile applications are seamless and full-featured. Coupled with the call flip feature, users transfer ongoing calls between linked devices with one click, offering mobility.
RingCentral’s app is straightforward, intuitive, and carries full platform functionality on its applications. However, for those who want simple calling features, it might take some getting used to. If this is the case, Google Voice is a simple application with straightforward controls enhanced by its Google Workspace integrations. Google Voice is available only to active Google Workspace users, and plan options include a free personal plan or paid subscription packages.
- Built-in customizability: Organize your display tabs and personalize your RingCentral app interface in the most helpful way. For example, your team members can select up to five tabs with calendars, tasks, videos, or other functions. This makes the app experience very convenient for each user.
- Call flip: Seamlessly transfer between softphone, mobile phone, and desk phone devices during ongoing calls. The call is placed on hold during the flip until the transfer is complete. This is particularly useful when you wish to continue a call on a different phone number or will be mobile mid-conversation.
- Extended voicemail options: There are multiple ways to check your voicemail using the RingCentral app. Users can listen to audio recordings, use voicemail-to-text (which allows you to read through your inbox), or read using voicemail-to-email (which compiles everything into your inbox).

Users easily place calls by tapping the dialer, locating a contact and placing the call, or clicking on the call or video icon and selecting contacts. Nextiva’s app allows you to transfer calls, add contacts, and screen share during meetings—all from your mobile device.
However, Nextiva users will find it has limited third-party integrations compared to other providers like RingCentral, which integrates with over 300 applications. Unfortunately, some important integrations are locked behind more expensive tiers. RingCentral is the mobile VoIP app with the most integrations and a robust API (application programming interface).

Make and receive calls and text messages anywhere and anytime with Grasshopper’s apps for desktop and mobile. Grasshopper offers 24/7 support access via phone, email, social media, and chat.
Unfortunately, Grasshopper allows international calling but lacks international numbers, which Phone.com’s offers.

When you cannot answer an incoming call, Grasshopper automatically sends an SMS message advising that you are unavailable, effectively informing your customer they’ve reached the correct number and you’ll get back to them.

How We Evaluated the Best VoIP Apps
To come up with this list, we reviewed several VoIP phone service providers with desktop and mobile softphone apps. From there, we narrowed the list of providers to the top seven based on pricing, simplicity of use, general and advanced features, and value for money.
The specific criteria we used to determine which of the best VoIP apps are strongest for small businesses include:
- Pricing: Budget is a significant consideration for small businesses when looking at service providers. Each provider offers different packages and pricing discounts. We analyzed the various plans, inclusion at each level, and whether free trials and VoIP mobile apps are available.
- Platform: VoIP apps vary significantly based on where you’re using them. For example, a softphone used on a laptop might have a completely different interface when used on an Android smartphone. For this reason, we evaluated each VoIP app based on the platform where it has its best performance.
- General features: Comparing service providers based on features enables us to measure whether the features offered at each level offer the best value for money. The best VoIP app for businesses provides mobile functionality and clear call quality. We also reviewed providers based on communication channels like business messaging and phone calls.
- Advanced features: The best mobile VoIP app for businesses are aligned with the features offered by web and desktop browsers. We only included VoIP calling apps that provide mobile and desktop apps with niche features, such as call reports and auto-attendants. We scored platforms’ unified communication (UC) features and international calling solutions.
- Expert score: We took time to explore and test the applications to determine how they compare. We based our expert score on personal use of the systems while considering user ratings. Each software provider is rated according to its standout features, popularity, and overall ease of use.
VoIP apps are great for small businesses because of their lower cost, increased accessibility, and clearer voice quality. VoIP apps are easy to use, simple to set up, and have advanced communication features that modernize a small business’ phone system. Based on our criteria, the best overall VoIP app is RingCentral. Besides its higher cost, it comes with comprehensive business calling features and a robust application.
