The receipt

Don’t trust us. Check.

Put your phone in airplane mode and keep tracking. Everything still works — because your health data was never going anywhere. No servers to subpoena, no SDK quietly phoning home.

Flo’s onboarding includes a consent screen to share your app activity with AppsFlyer, Firebase and TikTok. PinkyBloom has no such screen — there’s nothing to opt out of, because there’s nothing to share.

Voice logging

Don’t tap. Just talk.

When you’re in pain, the last thing you want is to tap through five screens of drop-down menus. Press the mic and say how you feel — Pinky does the rest, on your phone.

Many symptoms at once

One sentence, parsed into every symptom and mood it contains.

It hears nuance

“A little tired” and “exhausted” are not the same thing, and Pinky knows it.

Your voice stays put

100% on-device. No upload, no transcript in someone’s cloud.

Try it out

Press the mic. Say it once.

Imagine saying: “I have terrible cramps today and I barely slept.”
