What's RZLTS?

RZLTS makes it easy & free to add push notification ability, management & reporting to your apps. Record in-app user actions and later target those actions with specific messages that go right to a dedicated in-app inbox. Assign quality scores to certain actions and gain better insight into the true quality of your users.

The Only Unlimited Free Service

RZLTS is currently the only unlimited push messaging management service available free of charge. Most of the other services offer free plans which are restricted and become more expensive as you grow. We're able to offer free service by showing the Sponsored Apps section located at the bottom of each inbox message. Use the revenue calculator to get an estimate on your potential earnings.
