Get it!

This app is amazing! I’m so grateful to be able to use this to stay connected to my sailor. Letters get sent next day if you send between Monday-Thursday. You do have to pay but it’s worth it!!! You also get weekly updates so you know what your service member is going to be doing this week!

Amazing app and service.

This app and service are top notch. Knowing my letters are getting to the base helps. The costumer service is amazing.
