Great app

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.

Makes letterboxing easy!

This app is fantastic and makes it so easy checking for boxes nearby and making a list of boxes you want to find so you can access them offline too.

Could use an update..

The app works better than trying to navigate 2 separate websites.. However not all the letter boxes are showing up in my radius. The app only pulls up half the Cloud Atlas letterboxes in my town when the website shows them all. Kinda disappointing when you have to pay for this app. I have to use the website just to see the ones I might miss.

Developer Response ,

Thank you for purchasing the app and for your review. Unfortunately, Atlas Quest limits the number of boxes that apps like Clue Tracker can retrieve with one search. If Clue Tracker tells you that Atlas Quest returned its maximum, then you will need to search again using a smaller search radius. Also, make sure you log in within the app. Learn more here:
