Quo (formerly OpenPhone) has the best-reviewed mobile app at $15/user/mo. CircleLoop holds strong app store ratings for UK teams. Dialpad holds strong ratings for AI-native teams. wlur is our own product, so weigh that as you read. It's live now with one app for iOS and Android at $15/user/mo, and it has a 7-day free trial.
A phone system is only as good as its app when your team is out of the office. For most small businesses, that's most of the time. Many VoIP providers still treat mobile as an afterthought. Features that work fine on desktop show up late, buggy, or missing entirely on iOS and Android.
This list ranks providers by how their apps actually hold up. We used App Store and Google Play ratings, plus review counts. We also checked what reviewers on G2 say about mobile reliability, not just the desktop product. Prices are as of July 2026.
How we compared
This is desk research. We checked each provider's current App Store and Google Play listings for rating and review volume. We also noted how recently the app was updated, and cross-referenced complaints about mobile in G2 and Capterra reviews.
We didn't install and run every app ourselves across a full working week. Where a rating or review count is cited, it comes from the app store or the provider's own pages. Both are dated July 2026.

The list
Quo (formerly OpenPhone)
Best all-round mobile appThe most consistently well-reviewed app in this category, on both iOS and Android.
Quo (rebranded from OpenPhone in September 2025) was built mobile-first, and it shows. Shared team inboxes, call and text history, and voicemail transcription all work the same on the app as on desktop. That's not true of most competitors here.
Its 4.7 rating from over 3,000 G2 reviews reflects the overall product. But reviewers specifically call out the app as a reason they picked it over older, desktop-first VoIP tools.
- Standout:
- Feature parity between app and desktop, G2 4.7 overall
- Pricing:
- $15/user/mo, billed monthly (as of July 2026, quo.com)
- Makes sense if:
- your team works mostly from phones and wants app and desktop to feel the same.
Honest cons
- ·Newer AI features (Sona) are less mature in the app than the core calling features
- ·Some advanced analytics still need the desktop dashboard
- ·US-centric number coverage limits it for international teams
CircleLoop
UK teams wanting a lightweight, no-contract appA simple, reliable app for UK-based teams that don't want a long-term contract.
CircleLoop keeps its app deliberately simple. It handles calls, texts, voicemail and basic routing, without the AI layer or dialer complexity of some competitors. That simplicity is exactly why UK small businesses reach for it.
Its usage-based entry pricing (£5/user/mo plus usage, or £15 for unlimited) keeps the mobile experience affordable. That's true even for very small UK teams.
- Standout:
- No-contract UK-first pricing with a lightweight app
- Pricing:
- £5/user/mo + usage, or £15/user/mo unlimited (as of July 2026, circleloop.com)
- Makes sense if:
- you're a UK small business that wants simple mobile calling without a contract.
Honest cons
- ·Fewer advanced features than app-and-AI-forward competitors like Dialpad
- ·Smaller review base than Quo, so less data on long-term reliability
- ·Mainly UK-focused; less useful for teams needing US or global numbers
Dialpad
AI transcription and call summaries on mobileThe strongest app for teams that want automatic call notes without extra software.
Dialpad's AI transcription and call summaries run in the mobile app the same way they do on desktop. A call taken from a phone in the car still gets logged with notes automatically. Being Google-backed, its Android integration in particular is tight.
That AI layer is genuinely useful for sales or support teams. But it also means there's more going on in the app. A team that just wants a simple dialer and inbox may find it busier than needed.
- Standout:
- Real-time AI transcription available directly in the app
- Pricing:
- $15/user/mo, billed annually (as of July 2026, dialpad.com)
- Makes sense if:
- automatic call transcripts on mobile matter more to you than a minimal interface.
Honest cons
- ·Interface has more features than a simple team needs, per some G2 reviewers
- ·Monthly billing costs more than the advertised annual rate
- ·AI accuracy on mobile connections can dip on poor signal, per user reports
wlur
One simple app for iOS and Android, live nowour productwlur is our product, so grade this entry accordingly. It's a single mobile app built from the ground up, live today.
wlur is our product, so grade this entry accordingly. It's live now: one app for both iOS and Android. It has business numbers, simple team routing, and extra numbers in minutes. It also logs calls two ways into HubSpot, Salesforce, Pipedrive and Shopify.
It was built mobile-first, not as a desktop product with a mobile app bolted on. Because of that, app and desktop already have close parity, similar to Quo's approach. There's a 7-day free trial, no card required.
- Standout:
- Built as a single mobile-first app rather than a desktop port
- Pricing:
- $15/user/mo (£12.50, €14), July 2026
- Makes sense if:
- you want a mobile-first phone app with CRM sync and don't mind trying a newer name in the category.
Honest cons
- ·wlur is new, so it doesn't have years of app store reviews behind it yet
- ·App store review counts are still small compared to Quo's
- ·Feature depth is narrower than Quo's current app
JustCall
Sales teams dialing from mobileA capable mobile dialer for outbound sales, less suited to simple inbound answering.
JustCall's mobile app carries over its AI call scoring and dialer workflows. That's useful for a sales rep making calls between meetings. It also auto-logs calls and SMS into HubSpot from the app.
The 2-seat minimum and higher starting price make it a heavier commitment than Quo or CircleLoop. That matters if you just want a simple business number on your phone.
- Standout:
- Mobile dialer with AI call scoring and HubSpot auto-logging
- Pricing:
- $29/user/mo, 2-seat minimum (as of July 2026, justcall.io)
- Makes sense if:
- your team makes a high volume of outbound sales calls from mobile.
Honest cons
- ·2-seat minimum rules out solo use
- ·More sales-dialer features than a basic team needs
- ·Priced above lighter, app-first alternatives
Aircall
Teams already invested in Aircall's desktop dialerA capable mirror of the desktop app, but the desktop integrations are the real draw here.
Aircall's mobile app carries over its CRM click-to-call and helpdesk integrations. That matters if your team already lives in Salesforce or Zendesk on desktop. On mobile alone, it doesn't stand out against lighter, app-first competitors.
The 3-seat minimum applies no matter how many people actually use the mobile app. That's a real cost factor for a small or mobile-heavy team.
- Standout:
- Mobile app mirrors Aircall's deep CRM integrations
- Pricing:
- $30/user/mo annual, 3-seat minimum ($90 floor); as of July 2026, aircall.io
- Makes sense if:
- your team already has 3 or more users deep into Aircall's desktop CRM integrations.
Honest cons
- ·3-seat minimum makes it costly for very small teams
- ·AI features cost extra ($9-15/user), even on mobile
- ·Reviewers on G2 note the app feels secondary to the desktop dialer experience
Grasshopper
Basic call forwarding on the goThe app does the minimum well: forwarding, voicemail, basic texting, nothing more.
Grasshopper's app matches its overall approach: simple, flat-priced, no CRM sync, no AI layer. For a solo user who just wants calls forwarded to their phone with a professional greeting, it does the job.
Reviewers who compare it to newer app-first tools like Quo consistently say it feels dated. That's true both in the interface and in how fast new features arrive.
- Standout:
- Simple, no-frills app for basic call forwarding
- Pricing:
- $14-80/mo flat by plan (as of July 2026, grasshopper.com)
- Makes sense if:
- you want the simplest possible flat-priced app and nothing else.
Honest cons
- ·App feels dated next to app-first competitors, per reviewer comparisons
- ·No CRM sync in the app or desktop product
- ·Feature pace has lagged AI-native competitors like Dialpad
App-first pricing at 1, 3 and 8 users
At 1 user: Quo and wlur both cost $15/mo. Aircall's 3-seat minimum still charges $90/mo for a single mobile user. That's six times the cost for app access alone.
At 3 users: Quo, wlur and Dialpad are all $45/mo. JustCall is $87/mo. Aircall sits at its $90 floor.
At 8 users: Quo is $120/mo, wlur is $120/mo, Dialpad is $120/mo, JustCall is $232/mo, and Aircall is $240/mo. Choosing an app-first, no-minimum provider over Aircall saves roughly $1,440 a year at this size.

- 01If your team works mostly from phones, check for feature parity between app and desktop before you sign up. Quo and Dialpad both score well here.
- 02If you're a UK-only team who wants simplicity over AI features, CircleLoop's lightweight app skips the machinery you won't use.
- 03If automatic call notes matter most to you, Dialpad's AI runs the same on mobile as on desktop.
- 04If you're already committed to a CRM's desktop integrations (Salesforce, HubSpot), check that the mobile app mirrors those integrations. Don't just check the calling function.
- 05Read app store reviews from the last 90 days, not just the overall rating. VoIP apps update often, so older reviews can describe a different app.
Frequently asked questions
Which business phone app has the best App Store rating in 2026?
Quo (formerly OpenPhone) is generally seen as the strongest app-and-desktop pairing in this category. It's backed by a 4.7 G2 rating from over 3,000 reviews as of July 2026.
Do these apps work without a desktop computer?
Yes. For most providers on this list, the mobile app carries the core calling, texting and voicemail features. Some advanced analytics and admin settings (particularly on CloudTalk and RingCentral) are desktop-only.
Is Dialpad's AI transcription available on mobile?
Yes. Dialpad's real-time transcription and call summaries run in the mobile app the same as on desktop. That's per Dialpad's own product pages.
What happens to call quality on a bad mobile connection?
All VoIP apps depend on a stable internet or cellular data connection. Call quality and AI transcription accuracy can drop on weak signal, no matter the provider. That's per user reports across these apps.
Does CircleLoop's app work outside the UK?
CircleLoop's numbers and pricing are UK-focused. The app itself works anywhere with an internet connection, but its number coverage and support are built for UK teams.
Is wlur's app available to download?
Yes. wlur is live and available now on iOS and Android, with a 7-day free trial and no card required. Pricing is $15/user/mo (£12.50, €14). It's our product, so weigh that against its shorter track record.
Which app is best for a solo founder?
Quo, CircleLoop and wlur all avoid seat minimums, making them the most cost-effective for a single user. Grasshopper's flat pricing is also solo-friendly, though its app is more basic.
Do Aircall and JustCall's apps require a minimum team size?
Yes. Aircall requires a 3-seat minimum ($90/mo floor) and JustCall requires 2 seats. Both get billed no matter the actual headcount, per each provider's pricing pages.
Can I use one of these apps as my only work phone?
Yes, that's the standard use case for all providers on this list. Most support call forwarding to a personal device as a fallback if the app is unavailable.
How often do these apps get updated?
This varies by provider, and it isn't something we tracked systematically. Check each app's store listing for its last update date before committing. VoIP apps that haven't updated in months are a warning sign.
Last verified: July 2026. Prices from providers' public pricing pages on that date. wlur is our product; its entry above says so.
