App is buggy

Service works great and the web version so far is flawless. The app is very buggy though. I’m on an iPhone 12 Pro Max running iOS 14.3. If someone calls, my phone rings and it shows it’s coming from String, that’s great. But if I don’t answer that call, there is no Lock Screen notification and no badge icon to show that I’ve missed a call. In fact no clue unless I look at recent calls or open the app. Notifications for text messages work just fine. This has caused me to miss many calls from clients. Also voicemails will not play in app but do on web version. Love the product and idea but these bugs need to be worked out ASAP.

Game changer for our business

String has proved to be something of a game changer for our business. We have used other enterprise-based texting apps, and they were filled with errors, hidden fees, cumbersome to use, and functionality that seemed out of place and not useful for most day-to-day interactions with customers. String has been a breath of fresh air. The cost is extremely reasonable, in fact we are paying multiples less than we did previously. In addition we are getting a better service, as measured not just by ease-of-use provide a more important metric of customer engagement. Any business small medium or large that is looking to interact with their customers in a faster, friendlier and more customer focused manner should strongly consider signing up for String. It’s perhaps our most important app for making sales, increasing our sales, improving our customer engagement, and improving our brand image. We give it a very enthusiastic five stars.

A life saver

To my recollection this is my first time ever writing an App Store review, and I believe it’s worth it. I’m not sure how I came across String. As a small business owner I was never truly happy with our phones. Missed calls were a huge problem for us. We started by using Dialpad, a great office phone system but entirely too complex for our needs. We tried using call rules to route calls to different people at different times to avoid missed calls - but we were still failing. I then tried Google Voice, way too simple and lacked any kind of features. At some point after using Google Voice for a few weeks I came across String. I was intrigued, with a client base that is largely Millennials and Gen Z the text prompts upon missing a call spoke to me. What if I could automate some of our most commonly asked questions and get information in our prospective clients hands immediately even when we were out of the office? To top that off, what if our phone system acted like a mini CRM to keep us even more organized? String promised all of that. So I had to try it. I signed up and within 3 days I knew this was our solution. Not only does String work beautifully for our needs, but their team is INSANELY helpful. I had a few requests that weren’t part of their system (a professionally recorded voicemail greeting we had done by a voiceover artist) and porting in our office line of 15+ years. The String team made both of those requests happen with a smile. And they also checked in after. I can’t recommend this enough. If you’re a small business or soloprenuer do yourself a favor and give it a try.
