The DL app is much more useful at Disneyland than the TP Lines app. This is very different than at WDW. I go several times a year, and only use the Lines app for chat. The DL app is great. It has accurate wait times and fastpass return times. There are very few Liners who put in actual wait times at DL, most of the regulars on chat no longer do as we use a combo of maxpass/fastpass and single rider lines for most rides, also the wifi there is terrible and many do not want to use their data plans for submitting wait times. This causes the app to not work well for expected waits in the last few years. We were just discussing this on chat recently, if you want more up to date discussion, join us on the chat feature of the TP app. There are many more liners there than here on the forum.
