The app to get if you know someone joining the military
If you have someone going to boot camp or basic training this is a must download. The app allows you to send letters to boot camp straight from your phone. No post office no envelopes no stationary needed. Although I did still write letters I ended up sending more Sandboxx letters as my at the time marine officer candidate requested me to use sandboxx because he was getting mail faster. Not only do you get to send letters but every week they send you what your recruit is doing that week during training along with letter topics and suggestions in case you don’t know what to write about.
Whenever I had an issue with the app the customer support team was extremely helpful and responsive. All my issues were taken care of and I could focus on supporting my loved one with letters. This is a great app to keep our loved ones motivated during the hardest time of their life. I would recommend again and again.

Good but a bit pricy
I really like this app a lot! It’s very convenient when you don’t have the time to write a letter by hand and go through the process of having to put it in an envelope, writing the address, finding stamps then looking for a mailbox. It’s kinda like texting a message from the phone which is what everyone does nowadays. It also sends photos from your phone so you won’t need to print any to send them but only one per letter. It lets you know updates and changes the person you’re writing too is going to be going through at basic training.
I think my only issues is how many notifications it sends of when you send a letter, it keeps giving me three notifications at the same time saying the same thing, “you’re letter has been delivered”. The other thing is that letters are $4 each but they do cut the price a little when you by big bundles but you also get taxed.
For me, I think it’s pretty expensive but I would send daily letters to my husband while he was at basic and he got the letters very quickly. Usually when I got a call, he was pretty much up to date unless I said something that happened yesterday or couple days ago. The letters I sent from Sandboxx got received a few days after I sent it while hand written ones I got from my husband took a week.
All in all, Sandboxx is pretty good, letters are easier to write, less time consuming and they send the letters quickly. Only problem is the price of letters really.
Worse app ever
Sandboxx is awful. I wish there was a numerical rating and I would give it a zero. In theory, the morale booster credits SHOULD be an awesome feature. You would be able to buy a package of credits and then share them with your family and friends. However, the first issue is that you have no control over who uses your credits. Since the app asks you to invite people to the morale booster, that would suggest that the credits that you put in there would ONLY be available to those that you share the link with. Well that is incorrect. Your credits can be used by ANYONE, absolutely ANYONE who logs in and pulls up a letter to send to your recruit. That is irregardless of whether you know the person or not.
Secondly, I've had issues with Sandboxx releasing the entire list of individuals who had EVER sent a letter to my recruit. While they did adjust this policy AFTER I reached out about that, they refuse to inform you of who used your morale booster credits. If you don't want individuals to ask who used their credits, then you need to offer the ability for the individual to assign their credits to specific people.
If you want to use Sandboxx, stay away from the morale booster. It's more headache than it is worth.
