The Core Manual Log Is Available Free
You can enter readings from your glucose meter or CGM with the large numeric keypad in mg/dL or mmol/L. Manual entries are not limited by the daily camera allowance. Add fasting, before-meal, after-meal, or bedtime context, plus notes and custom tags when they help explain a value.
Saved readings remain available in your on-device history. The free plan includes 7-day and 30-day chart views, so you can review a recent pattern rather than relying on individual numbers alone.
Useful Extras Have Clear Free Limits
The free plan includes one camera scan per day, while manual entry remains unlimited. It also includes one import from Apple Health and one PDF or CSV export each month for a date range of up to 30 days.
The free version may display interstitial advertising. Non-personalised ads are the default; personalised ads require App Tracking Transparency permission. Raw glucose values, medication records, note text, and Apple Health samples are not used for ad targeting.
What Premium Adds
Premium removes advertising and adds unlimited camera scans, longer chart history, unlimited PDF and CSV exports and date ranges, continuous Apple Health import and write sync, JSON backup and restore, and medication tracking. Current pricing and any trial eligibility are shown in the app before purchase.
You do not need Premium to start a manual log. The simplest way to decide is to use the free workflow first and upgrade only if the additional automation, history, exports, or backup fit your needs.
Gludiary is free to download but is a freemium app, not an entirely unrestricted free service. Limits and Premium availability can be reviewed in the app before purchase.
