iPhone
Log a reading without looking at the screen. Say “Hey Siri, log blood sugar in B-Check” and you're done. Built for VoiceOver from the first line, not bolted on.
A logbook for blood sugar and blood pressure that you speak to, and that speaks back.
It does not assume you can see the screen and tap precisely.
It was built for people losing their sight to diabetes, for people whose screens
have gone dim, and for anyone holding a meter with no spare hand.
■ Speak your reading
Tap the microphone and say “one twenty”. It goes straight in.
For blood pressure, “one twenty over eighty” works in one breath.
It finishes on its own when you stop talking, then reads back what it saved.
■ You don't have to open the app
Ask Siri directly.
· “Hey Siri, log blood sugar in B-Check”
· “Hey Siri, last blood sugar in B-Check”
· “Hey Siri, find a past reading in B-Check”
· “Hey Siri, today's blood sugar in B-Check”
No hunting for the app, no scrolling a list.
■ If you use VoiceOver
Each entry reads as one sentence — value, time and context together.
Edit and delete sit in the rotor actions, so you never hunt for a small button.
When VoiceOver is on the app stays quiet instead of talking over it, and shows no ads.
■ If the screen is hard to read
Pick a text size on the first screen and watch it change as you choose.
Increase contrast to drop the faint grey text and put clear outlines back.
If your iPhone is already set larger, that setting wins.
■ A table for your doctor
One export gives you a clean table of dates and numbers.
Send it ahead of your appointment and it's on screen when you walk in.
■ Also included
· Pulse alongside blood pressure (switch it on in Settings)
· Two-way Apple Health sync (optional)
· Reads values your CGM put into Health
· Trend charts from one week to everything you've logged
· Reminders for morning, bedtime, and after meals
· Korean and English
■ Everything stays on your iPhone
No server. No account, no sign-in.
Nothing is ever sent anywhere.
■ Please note
This app is a logbook.
It does not interpret your readings or offer medical advice.
The ranges it shows are commonly cited reference points; your own targets may differ.
Always discuss your readings with your care team.
