What's New in Beiwe2

2.5.7

July 2, 2026

This update squishes a few bugs: - The app no longer doesn't not crash when processing double negatives in complex survey logic. Other uncertain logic is now definitely very, very, Very certain, and must take a weekly test to prove it stays that way. - While the old cancel survey and end task animations were a bit longwinded... the bubbly iOS 26 one was so positively glacial that its slow-motion momentum could cancel the whole app. It has been let go. - Sensor data could theoretically drift slightly on the ocean of time.

Used with a study and worked great. Old login issues seem to have been solved

Terrible app

I’ve been involved in a study but I haven’t been able to log in for months. With a previous update, the app suddenly told me I had the wrong password when I absolutely know it was correct. I copied and pasted it from a password keeper and the app still said it was wrong. Now when I try to log in, the app just shuts down and kicks me out. What is going on with this? I can’t participate in the study anymore.

Too Many Issues with Log In

After a recent update, my password would no longer work. Like others, I was certain I was entering the correct password. Now, the app quits when I try to enter any password. I am disappointed because the study that I was participating in is very important, but this app has too many bugs to make use feasible.

Can’t contact study staff

I’m supposed to contact study staff to reset my forgotten password, but there’s no contact info provided and nothing in my email that includes the word “Beiwe” or “Beiwe2.”
