User Reviews

String is praised for organizing text workflows with CRM-like features and a second business line, boosting productivity and engagement. However, many users report persistent bugs, weak support, onboarding barriers, notification gaps, and platform limitations that undermine reliability. The product offers strong value when it works, but consistency and onboarding quality are common pain points.

Pros

Robust text management with tagging, templates, lists, bulk messaging, and automation that feel like a CRM for your texts.
Boosts productivity and efficiency by automating workflows and reducing manual follow-ups.
Provides a separate business line / second number at a reasonable price, helping keep work and personal life separate.
Texting works well across mobile and desktop, enabling fast client communication.
Strong potential to improve customer engagement and sales through organized outreach.

Cons

Recurring bugs and instability in the app and web interface (loading issues, misloaded threads, voicemail problems).
Customer support is often slow or inaccessible, leaving users without timely help.
Onboarding and sign-up are frustrating (invite codes, login after reinstall, limited number picker).
Missed-call and message notifications are unreliable (no lock screen/badge alerts; missed calls may not show).
Feature gaps and platform limits (no iPad app, limited CRM integrations, and other missing functionality).

I wish I did my research before switching my business line to string. The calls would drop within 3-10seconds and then I would not be able to call back. Then my line cut out completely and sent people straight to voicemail. I lost so much business. Their customer support is non-existent. You cannot get anyone on the phone and have to wait days for email replies that are generic. I finally got my line changed to Ring Central and they are amazing! Highly recommend.

I’ve used String now for 4 years, Nov 2020 to be exact, and when I tell you this app does not get better - even that’s a case understatement. I was worried, but later had high hopes when they were bought out by Number Barn, yet they seem to have forgotten about the app too. I’ve also been in contact with their support team to try and resolve issues. They’re fixed for a few weeks, but then the issues come right back. • Most times the website loads to a white screen, I’m lucky to even get in • App loads message threads out or order • tapping into a thread does not load any part of the conversation • sending a message in the thread works, but you wouldn’t know because, well, the thread doesn’t load • Tapping a thread with a contact you thought you were going to loads an entirely different number/contact at the top, still with no content At this point, I’m only using it for notifications that messages came in so I can then go spam reload / clear cache on my computer until the page loads so I can respond to clients.
