Horrible and unusable on Android. It will not respond. Installed and uninstalled 3 times. Locked up my phone, slows down the phone, and crashes the phone. Merlin and iNaturalist work perfectly on my Samsung Galaxy A 54 5G. It's not my phone, it's this app. Seems to work OK on a colleague's iPhone, but nobody with an Android likes it. I have to carry a notebook into the field. I'm on a team checking 66 nest boxes weekly. This needs to be fixed.

Sorry to hear you are having trouble. Please try the new version 3.4.8 in the Play Store.
You may also need to clear the app's data (https://www.samsung.com/sg/support/mobile-devices/how-to-clear-the-app-cache-and-data-on-your-galaxy-phone/). You will need to login afterwards.
If this doesn't help please contact us here - NestWatch@cornell.edu

UPDATE: Have used this app for the last 5 yrs. Started this season, and app suddenly does not work AT ALL! Freezes up immediately upon opening, sometimes crashes. Re-installing does not help. Very disappointed. ā¹ļø OLDER: I love the NestWatch program, and the new design of the app is much more intuitive. It also seems to run more smoothly on my phone. Samsung S24 FE running Android 14.
