PerfectCSR puts a customer service team in your pocket. Train your own AI agent on your website, documents, videos, even a voice note and it answers customers in your brand's voice, around the clock, across your website, WhatsApp, Messenger, and more. It doesn't just wait for questions: with proactive chats, it sees who's on your site in real time and opens the conversation before a visitor bounces. When a conversation needs a human, the handoff is seamless, one tap transfers the live chat to your team with the full thread, the customer's details, and the page they came from already attached, so no one starts over. It captures every lead's name, email, and number, books real appointments into Google Calendar or Calendly, and turns unresolved questions into support tickets automatically. Manage everything on the go: monitor live chats, review conversation logs, track your resolution rate on a clear dashboard, set team access levels, and refine your agent's responses in minutes. PerfectCSR connects to the tools you already use Shopify, Salesforce, Zendesk, HubSpot and keeps your data encrypted end to end, never sold, and never used to train AI for any other business. Start free, go live in under 10 minutes, and turn every conversation into a reason for customers to come back.

Bugs and requests

nRF Connect for Mobile

Reported bugs

4 issues
  • Can't read data from Bluetooth device
  • Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
  • Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
  • Cant go past the initial announcement. The app is unresponsive to the taps.
