Ratings and reviews

I've been asking Sideline for years to include a search feature for call, transcribed vm, and sms history. I use Sideline for business and want to recall names, phone numbers, and messages of past clients and experiences. They say they want input but rarely add new features, and none of the ones I suggest. I might start looking for another app that does what I need.

I used to like this app. Was good for me to have a personal number along w my business number, w out a huge price point. But it has gone extremely downhill the last 6 months. There are service outages at least every 2 days. Pics rarely send, even on wifi. No calls come through. It just automatically says "missed call" when it didn't even ring. It's just really gone downhill. 😞 really disappointed.

The app works good. My one issue is the contact list. The app REQUIRES your contact list in order to work properly. However Sideline, think about this: people want a second number to give out to folks who are Not friends, Not family, and usually business associates or one-time calls. So why would I want my personal Friend/Family contact list on the app?? It doesn't make sense. Adding your contacts should be optional, or have a completely separate contact list within the app.
