A simple, private tracker for blood sugar and meals during gestational diabetes. No account, nothing uploaded. Free to use, with an optional one-time upgrade for a doctor-ready PDF.
What's inside
Built for the day-to-day of gestational diabetes: quick to log, calm to look at, and completely yours.
No account, no login, no server. Nothing is uploaded, shared, or sold — ever. Your readings are yours alone.
Turn your log into a clean, formatted report to bring to your OB or midwife — no more crumpled notebook.
Pro is a single one-time purchase — about $14. No subscription, no monthly charge, nothing to cancel later.
Tag each reading the way your care team asks — fasting, before a meal, 1-hour after, 2-hour after, bedtime. Tap and go.
Jot down what you ate and add a quick note, so patterns are easy to spot when you look back.
Gentle color feedback and daily stats. Set your own target numbers to match what your provider gave you. (Pro)
A gestational diabetes diagnosis often arrives with a meter, a schedule to prick your finger four times a day, and instructions to write it all down. It's a lot — especially when you're already tired and a little anxious. So we made Sugar Log quiet, private, and simple: open it, tap in your number, and get on with your day.
Pricing
The core app is free forever. Pro is a single purchase — never a subscription.
Questions
Completely. Sugar Log stores everything directly on your phone and nowhere else. There's no account and no server, so nothing is uploaded, shared, or sold. One honest note: because your data lives on your device, we can't recover it if you delete the app — the free backup/CSV export is a good way to keep a copy.
No. There's no sign-up, no login, and no email required. Open the app and start logging.
Yes — iPhone and Android. Sugar Log runs in your phone's browser, and you can add it to your home screen so it opens just like a regular app. No App Store download needed.
Never. The core app is free forever. If you want the doctor-ready PDF and a few extras, Pro is a single one-time purchase — no recurring charges.
No. Sugar Log is a tracking tool to help you record and organize your readings. It isn't medical advice or a medical device, and it doesn't diagnose or treat anything. Any target numbers are the ones you enter from your own care team. Always follow the guidance of your OB or midwife.
