Summary
Your pregnancy wellness journal.
Log your readings and meals, review your trends, and share your journal with anyone you like. All your data stays on your device — no account, no cloud, no compromise.
I created this app to help my wife during her pregnancy with our daughter. Her clinic wanted her to track her readings and meals to maintain good health — for her and the baby. It was a manual process, and I thought: surely there has to be a better way. This app replaces the paper and pencil that can be hard to read, easy to lose, and just too cumbersome to keep up with.
Log fasting, post-meal, and bedtime readings. Instant colour-coded feedback against your personal targets. Add notes to any entry — context, reminders, or anything else worth remembering.
Record everything you eat with quantity and food name fields. Point the camera at your plate to document your meals. Optional free Gemini-powered AI camera can identify food items automatically — requires a free Google AI Studio account.
Current-day strip view, custom date range stats, averages, and time-in-range percentages — all accessible right on your summary screen.
Generate a formatted PDF of your journal for any date range. Print, save to Files, or email it to anyone with one tap.
Daily reminders for every check-in. Meal-triggered reminders fire automatically 1–2 hours after you log a meal — and cancel themselves when you log your next reading.
All data stored locally on your device. No account required. No cloud. WiFi Transfer moves data device-to-device without any server involved.
