What's New in Safr

1.5.3

November 6, 2026

We're always listening to your feedback and working to make Safr better and easier to use. Here's what's new: • Sources you can check: health answers in Chat, and the health information throughout the app, now link to trusted health sources. • Clearer tips: your logging tips now match what you logged, and "Log an LH test" takes you straight to logging. • Better test timing: Safr now suggests when to take a home pregnancy test. • Straight to your results: after you subscribe, Safr opens your results right away. • Fewer interruptions: subscribers no longer get offer notifications for a plan they already have. • Clearer Oura syncing: if Oura can't share your data, Safr now tells you why. • Easier setup: the privacy and consent screen fits on every screen size, even with large text. Thank you for helping us make Safr better.

okay so i downloaded this kinda as a joke bc my friend sent it to me but like?? it’s actually SO useful. i’ve been using flo forever and it’s fine but it never really told me the stuff i actually wanted to know, like in normal girl terms. safr literally just tells you if you’re in a safe window or not. no weird clinical wall of text, no “consult your healthcare provider 🙂” popup every two seconds.
the pregnancy test thing is lowkey a lifesaver. i was NOT about to walk into CVS with my mom’s friend working the register. being able to do it through the app was so much less stressful, i almost cried ngl.
onboarding was cute, didn’t take forever, and the ui actually looks like someone under 40 made it. the only thing is i wish premium was a little cheaper bc i’m literally in high school 😭 but other than that no notes.
would recommend to literally every girl i know. sending to the group chat rn.
