On 5/1 I received a call from a client and went to text the client some information. When I tried to send the message I now get a subscription expired notice and I cannot communicate with my client who is waiting for a response. Now phone number is provided for customer support. Crazy bad for business. I don’t recommend using this app! ### 1/5 — No Customer Support & Longtime Subscription Not Working *2025-04-27, version 2.5.4* I had been utilizing the SwitchUp app for years and all of a sudden it stopped working. I kept getting messages that “my subscription failed to send to backend” and another message that stated my “subscription couldn’t be found”. When I tried contacting customer support, I received a single message many weeks after having reported the issue. I contacted Apple Support, who of course, advised me to contact SwitchUp app support. The app support is terrible and non-existent. I lost years of contacts/messages/calls. They had no problem deducting the monthly app fee and never missed a beat ensuring receipt of their money but yet the customer service was no where to be found. ### 1/5 — Disappointed *2025-04-17, version 2.5.4* Their app is not working like it should, emailed multiple times. Could not and still can not access the app on iOS . Not sure if it is an apple issue or SwitchUp app issue. But this needs your be fixed. I’m losing money paying for the subscription. ### 1/5 — This App is a joke they don’t value their customers *2025-04-15, version 2.5.4* I purchased an annual subscription and all I could get it’s an error as occurred…and I’m loosing a tons of customers just because of this. ### 1/5 — Don’t subscribe *2025-04-10, version 2.5.4* I have a subscription which I pay annually. My subscription is valid through August 2025. However I keep getting notifications that my subscription has expired, that SwitchUp is having technical difficulties…I have submitted 7 emails to the customer service department and technical support desk and now 5 weeks later no one has returned my call or responded to my request. I cannot currently send or receive texts or calls on the SwitchUp number. I have no idea how much business I have lost in the past 5 weeks. SwitchUp doesn’t have a posted number to call when their service isn’t working. So SwitchUp if you’re reading this, please contact me. ### 1/5 — Malfunctioning *2025-04-10, version 2.5.4* It often malfunction and there is no way to contact any kind of customer support ### 1/5 — Subscription error👎🏽 *2025-04-03, version 2.5.4* My incalls are always missed call and now it’s unable to verify my subscription and you charged me isn’t that disgusting?? I uninstalled it and tried to install again now am not able to login says my subscription couldn’t be verified ### 1/5 — Subscription *2025-04-02, version 2.5.4* Why there’s always a problem with subscription service. It fails many times after being updated ### 1/5 — App crashed a week ago *2025-03-31, version 2.5.4* Switchup crashed a week ago. I reached out to Support over a week ago every day for the past week to let them know that I have no access to the second phone number which is the primary number for my tax preparation business. It is the end of March at the peak of my business. I have prepaid for this app and yet I have absolutely no contact from SwitchUp to this point. Absolutely worst customer service. I have emailed them. I have left messages over and over and yet I have not got one response. ### 2/5 — Unstable and often useless *2025-03-29, version 2.5.4* I tried to love this app for my business, since I wanted something with both templates and auto responses. It often doesn’t get messages for a long time and is now unable to verify my subscription even after being charged twice. I haven’t been able to get my messages for days which is terrible for business. I’ll use the tried and true from now on, awful experience and way too expensive. ### 1/5 — Do Not Use Them *2025-03-27, version 2.5.4* I started using SwitchUp for a business I started 3 years ago and it’s been one problem after another. They keep making you up your service to get the same benefits you got when you signed up and if you do not upgrade you lose everything but a call in. I have not been able to get access to my account in over 4 days, not receiving my calls, texts, or vm’s which has cost me a large amount of money. Getting a hold of customer support is nonexistent, I’ve emailed and send message for day and multiple times with zero reply. I am contacting Better Business Bureau, Apple, and my business lawyer. If I can prevent one person from this horrible company this review was worth it. ### 2/5 — Having issues *2025-03-26, version 2.5.4* Disappointed is an understatement. Been trying to use it all morning. Downloaded the app, paid the $7.99 for the month, when I went further into the app it froze. Restarted the app a couple of times, every time I tried to use it Errors would pop up, closed it, restarted and the same issue all around their features, from setting the office time, automatic replies, and even calls. Haven't been able to make not even 1 call. I've submitted (2) reports already so lets see if they fix whatever it is before the day is done. Otherwise, I'll have to cancel and find another option. ### 1/5 — You are poor 😡 *2025-03-25, version 2.5.4* I paid for a subscription but they wouldn't allow me to access the app. “Our server could not send your subscription to our backend” ### 1/5 — 50% useless *2025-03-20, version 2.5.4* All incoming calls fail, regardless of settings. Only able to do outgoing. ### 1/5 — Texting problem *2025-03-13, version 2.5.4* This app used to work great and suddenly customers can’t receive any of my texts I erased the app and redownloaded it multiple times nothing seams to work and I can’t get anyone to help me resolve this issue will have to look for a new service provider, it’s a shame use to love this app ### 1/5 — Customer service 👎 *2025-03-06, version 2.5.4* Their customer service is awful. There’s only one way to get ahold of them and that’s by reporting a problem through the app which they hardly ever respond to. They were so good for the first couple years I had them but for the last year it’s been nothing but problems. Currently, my incoming calls are showing a missed call notification but my phone never rings. I am missing a ton of business calls and losing customers. Extremely disappointed in this app. Wouldn’t recommend. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can’t Port Numbers Out *2026-06-03, version 2.5.5* Customer Service will not reply, no instructions on saving your number or porting it out before they go out business. I’m pretty sure this is against some telecom regulation or breaking some law. It’s funny, because I looked through the developer’s app and saw I had purchased another pro paid app. I guess I will uninstall that one too, now. ### 1/5 — Wtf *2025-12-02, version 2.5.5* Awful can’t make out word calls ever ### 1/5 — stolen money *2025-08-31, version 2.5.5* App not work ### 1/5 — Stole my money! *2025-08-21, version 2.5.5* I was an early adopter of this app and even met with developers in the early days to provide user feedback. A couple of months ago I got a notification that the app would be discontinued and no longer supported as of June 2026. Fine, my annual subscription had just renewed and would expire in May 2026. Then, a couple of weeks ago the app stopped working saying ‘my subscription status could not be verified’ and telling me to pay again to regain access. Ummm NO. I contacted customer support and still haven’t heard back. ### 1/5 — App Doesnt work *2025-07-06, version 2.5.5* do not buy this app. it doesnt work since the first day i paid for the subscription, no customer service and no refund…. ### 1/5 — This app went out of business *2025-07-01, version 2.5.5* Had a subscription, app said they were shutting down in 2026, my subscription was paid automatically monthly until July 7 2025, was unable to use app in May 2025. No tech support at all. ### 1/5 — Awful *2025-06-25, version 2.5.5* Paid for a year only to find out that the app is being pulled from Apple. Want a refund cannot get in touch with anyone. ### 1/5 — Great app but needs a few more bells *2025-06-04, version 2.5.5* I just found out I can not keep this number after January 2026. ### 1/5 — Going out of business *2025-06-03, version 2.5.5* The app when launches now states they are going out of business. Buggy, slow app. Glad to see them go ### 1/5 — Why not working since for days *2025-05-28, version 2.5.5* I have been having issue with my switchup, it doesn’t working at my location what maybe happen ## Most praised reviews (10 highest-rated) ### 5/5 — I need monthly subscription *2026-02-14, version 2.5.5* Kiara. ### 5/5 — Sad to see the app go *2025-06-06, version 2.5.5* Definitely served its purposed. Great job guys 🙏🏾 ### 5/5 — Calling system *2025-03-29, version 2.5.4* My incalls are always missed calls and I can’t call out with your number that’s not wise. ### 5/5 — Amazing *2025-03-20, version 2.5.4* High level of functionality and comes with a free trail. So you don’t think this is a paid review I hate minorities. ### 5/5 — Unreceived messages *2025-02-08, version 2.5.4* I cannot receive messages ### 5/5 — Good work *2025-01-30, version 2.5.4* It is really working perfectly ### 5/5 — H *2025-01-21, version 2.5.4* The app have been malfunctioning for a week now and it stopped working for over 50hrs without any reason. That’s not a good idea from your company ### 5/5 — Dandymax *2025-01-13, version 2.5.4* Working perfectly 👍 ### 5/5 — cancellation plan *2024-11-14, version 2.5.4* how do i cancel my plan ### 5/5 — Love the bu *2024-09-12, version 2.5.2* You --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
