View the TrueAchievements app achievement list
Unlocking an achievement in the app before trying to view the achievement list will make things much easier as it will show up on your profile instead of simply on the app. No fear, you will unlock "The First Rule of TrueAchievements..." the first time you launch the app.
After you have earned the first achievement, head to your laptop, computer, or browser capable device and request an update to refresh the tracker for your account. Now reload the TrueAchievements app and you will see the app right on the front of your games recently played and unlocked an achievement in. Click on the game and the achievement will unlock as you view the list.
