First Fork is a glucose logger built for gestational diabetes — the two-hour window after every meal, the reading, and the grid your clinic wants to see. Try First Fork free for 7 days. After that, the app requires a Monthly subscription or a one-time Lifetime purchase. Every feature described below is part of that plan. Log a reading in seconds. Photograph your meter and First Fork reads the number for you, or type it in by hand. See your countdown without opening the app. A Live Activity on your Lock Screen and Dynamic Island shows exactly how long is left in your two-hour post-meal window — something no other gestational diabetes app offers. Add the Apple Watch complication to check it from your wrist. Walk into every appointment with the exact grid your clinic hands out — generated from your real readings, ready to print or share as a PDF. No ads. No account. No cloud. Everything you log stays on your device — nothing is ever uploaded, shared, or sold. First Fork is a logging tool, not medical advice. Always follow your care team's guidance for testing, targets, and treatment. Terms of use: https://firstfork.app/terms

First Fork's advantage is update cadence (every 5 days vs monthly). On price, rating, ads and device support there is nothing between them.
