Comments on Sandboxx for Android

★★★★★ Paulina 10 Cibrian · Apr 24, 2026

Want to thank Kris and Sandbox so much for the amazing idea of having this app for us parents and family, this way we have the opportunity to communicate with our sons and daughters faster and secure. Also, I enjoy the way Kris describes with such details each phase of their CBT our soldiers to be been, and every week event, so interesting. That way I can cheer up and pray for my son in advance, I feel close to him being able to write almost every day. To me Sandbox feels like family Thank you

A very great way to send a letter fast to my son, so he can get the support and inspiration he needs through recruit training.

AVOID. SIT did not receive one, paid extra for, return letter supply out of 10 letters! $5-7 per letter, and I didn't get what was paid for! SCAMMING MILITARY FAMILIES!!! **edit** They called, basically said its impossible and acted as if we were lying, or she was too stupid to open mail. I haven't asked for a thing! She's been there weeks unable to respond to me which was a service they were paid for. Now she's on her way home, and they want to send her the prepaid return stuff for her to use

★☆☆☆☆ Christina Galindo · May 6, 2026

After 2 letters I'm not able to send the remaining 3. The screen I'm writing the letter on doesn't scroll down as yiu write so at a certain point you have no idea if you have any typo because the screen is stuck at the first paragraph of your letter. Also, now the send has issues saying my recruiter can't be found. Would never recommend this waste of money. Just use the good ol' snail mail...they will love your personal stationary and notecards so much more.
