  • Great app

    By Flwr53
    I’ve been using this letterboxing app for at least 4 years and have never had any problems. It’s so convenient when traveling to pull up a quick search for nearby boxes. I also like the save feature so you can download the clues for later viewing in an area where you know there won’t be cell service. I like being able to log the find from the field.
  • Great App and much needed update - thank you!

    This is the best app for letterboxers! Thank you so much for the recent update and the iPhone X support.
  • Useful, but some features would be nice

    By Cammyt5
    I have two problems so far: 1) As far as I know, you can't read other people's logs. This is a big annoyance for me. 2) I wish there was an option to move pins around on my own personal map. For example, if the box location is only as specific as a town, but I know it's in a certain park, I could move the pin to the park on the map so that in the future I know where that box is. Otherwise, the app works great, we've already quite a few boxes. :P The compass feature was very useful.
  • Disappointed

    Got the app and have tried unsuccessfully to find three different boxes with my children. Very disappointed.
  • Very Helpful

    This app has been invaluable in my searching on the go. Would highly recommend to anyone hoping to find letterboxes wherever they are.
  • Love this app!!

    By Love these two!!
    The more I use it, the more useful features I discover, and the more I LOVE IT! So easy, so versatile! I really like the way it facilitates access to both AQ and LbNA clues, the mapping feature and in-app directions to box are wonderful!! logging finds could not be easier! Thanks for an awesome app! Recommended it to several friends who then dumped other, less agile apps.
  • Great App!

    I just took an 1800 mile road trip and was able to use the "Nearby" function without fail. Keep up the good work, this is an EXCELLENT app.
  • Great!

    By KtSpaghetti
    So far so good! I love that it combines Atlas Quest and lbNA since they each have different boxes posted. I haven't used the app letterboxing yet, just browsed through it, so I can't give it 5 stars but it looks promising!
  • Great App

    I wanted a Letterboxing app so I wouldn't have to go to the website, log in, search, and pick. There are two apps available. The other one had great reviews, but a lot of comments on features that would be great to have. This app, although I had to pay more for it, has all the features the other app is missing. I love that you can choose between AtlasQuest and LbNA. The interactive map feature is exactly what I wanted. Best of all, it is fast. I just downloaded this app and haven't even had a chance to use it yet. I hope it is as awesome in use as it is in initial reviewing. I will update my review once I have a chance to actually use it.
  • Excellent for saving - a few quirks

    By ChuckNoTheOtherChuck
    I love the “Saved” letterbox feature - I use it to categorize into parks or neighborhoods and it saves me from having to search again. However the search has some problems. I tried to search for a box with a numeric name and it changed the search from name to box number so I had to go to the website on my Safari browser and get the box number and put that in in order to save that box on this app. Also the search results only give you 50 boxes and some boxes that I remembered seeing online are not found. This app could be vastly improved just by adding more criteria to the search feature.
