Kayzen vs. OneSignal

I think One Signal is very well suited for mobile app owners who want to be in touch with their user base more easily by sending push notifications and in-app messages. I'm not sure how well that works for SMS messaging as I haven't yet tried it. I wouldn't necessarily recommend it if your in-apps are very rare.

• Is still in development: we know OneSignal is still in development and sometimes it takes longer to create or fulfill certain features.
• Payment: payment menu is not at the glance, [and] is just difficult sometimes to find -it is a minor issue.
• Send to certain custom segments through specific OneSignal IDs; you can do it though API doing a GET call with tools like Postman. If this can be done from OneSignal it would be great.

I give an 8 in this question mainly for 2 reasons: the products even if they look like complete and are highly customizable and usable, they are still missing some logical features. For example, send messages to a list of users - now days you can do it with postman and get calls. A second example is App messaging that is still in development and has many opportunities.

Their customer support has been top-notch. They are able to assist you in getting through any problems that you may have and respond in a very timely manner. I've dealt with them on 4-5 instances over the years and my issues were always resolved within a matter of a few business days.

In my opinion, OneSignal documentation / API is more friendly [than] Firebase. Maybe because Firebase is already "too big," but OneSignal is focused on one solution that giving our notification through to our customer. In that case, OneSignal is chosen by our company. Several years after that, Firebase announced it supported [the] iOs platform too but our company already using OneSignal to our notification provider.
