Track blood sugar, insulin, meals and A1C in one simple diary. See trends, set reminders and export clear reports when you need them. Managing your blood sugar shouldn't feel like a second job. Blood Sugar Tracker gives you a clear, organized log of every glucose reading — so you can spot patterns, share meaningful reports with your doctor, and feel genuinely in control of your health every single day. Whether you're living with Type 1 diabetes, Type 2 diabetes, gestational diabetes, or navigating prediabetes, this app was built around one goal: making glucose tracking effortless and informative. No cluttered interfaces. No confusing menus. Just a fast, focused experience that works the way you actually live. ▸ Log glucose readings in seconds — enter your blood sugar in mg/dL or mmol/L, tag the reading as fasting, before meal, after meal, or bedtime, and add a free-text note if something unusual happened. The entire entry takes under ten seconds. ▸ Beautiful, readable charts — view your glucose trends across the day, week, or month with interactive charts that highlight highs, lows, and time-in-range at a glance. Color coding makes patterns obvious without requiring a statistics degree. ▸ HbA1c estimation — the app calculates an estimated A1C value from your logged readings, giving you an ongoing snapshot of your long-term glucose average between lab visits. ▸ PDF export & doctor sharing — generate a clean, professionally formatted PDF report covering any date range you choose. Email it, AirDrop it, or print it directly before your next appointment. Your doctor gets the full picture in one document. ▸ Insulin & medication tracking — log your insulin doses and medications alongside each glucose entry. See at a glance how your insulin timing relates to your post-meal readings. ▸ Target range customization — set your personal glucose target range in consultation with your care team, and the app will visually flag readings that fall outside your targets. ▸ Fasting glucose tracking — dedicated fasting tags make it easy to isolate and review your morning fasting values, a key metric your doctor will want to discuss. ▸ Statistics & averages — see your 7-day, 14-day, and 30-day averages, standard deviation, and percentage of readings within range — all calculated automatically. ▸ Notes & context — add free-text notes to any entry: illness, stress, exercise, travel, or anything else that might explain an unexpected reading. Picture a typical week: Monday morning you log your fasting glucose the moment you wake up, and the app's reminder made sure you didn't forget. After breakfast you log your carbs and the post-meal reading ninety minutes later. By Thursday you notice on the chart that your after-dinner readings are consistently elevated — something you hadn't caught before. You add a note, adjust your evening routine, and by the following week the trend line has shifted. Before your quarterly appointment, you tap Export, select the last three months, and hand your endocrinologist a PDF that shows every reading, every insulin dose, every carb count, and the estimated A1C — no scrambling through paper logs or screenshots. Your health data belongs to you. Blood Sugar Tracker stores everything on your device. Nothing is uploaded to external servers without your explicit action. When you export a PDF or share via Apple Health, you are in complete control of what goes where. There are no hidden analytics pipelines, no advertising profiles built from your readings, and no third-party access to your health information. Take the guesswork out of glucose management. Download Blood Sugar Tracker today and start building the clear, consistent log that you — and your doctor — have always wanted.

Good hassle-free app

It’s a good app. Minimal, without all the excessive bells and whistles. The one time fee is a lot better than the usual monthly subscription. I would like to add, however, that it would be nice if there was a little indicator for where your glucose was at like the other apps have. Being high would be red, being green would be in range and being blue would be low. Honestly, that’s just something I like to see as a visual person when looking at my glucose readings for the day. It helps me keep in check on what I should be focusing on next. Overall, good app!

Thanks so much for the kind words!A color-coded indicator for glucose ranges has now been added — red for high, green for normal, and blue for low — just like you suggested. It should make daily tracking easier, especially for visual users.If this update improves your experience, feel free to update your review and consider a 5-star rating. Your feedback truly helped shape the app! 🌟

I wanted an app without frills and without monthly fees. This app is that. I just needed a place to register my daily glucose level plus make a note or two if I’m feeling dizzy or have a reaction to certain foods. This app is perfect for that. I didn’t need an app explaining what I should eat drink , or how often I should exercise. I’ve already done my research on all that. I was tired of carrying a notebook with my totals to and from the Doctors office. This is easier, I always have a phone with me anyway. The doctor can look at this and can easily scroll up and down, or look at the graph. Thank you for making a simple app. I do not begrudge the $4.99 charge for opening all the features. Just pay once and no yearly costs! EllaMay

All of my readings are importing over as Before Breakfast. Would be nice to have the ability to change tags could be user-error but I can’t figure out how to change them. I can manually add a reading and choose the tag but the imports are not editable.

Hey! Thanks a ton for using the app and for flagging this.Apple Health doesn’t provide meal/time tags with glucose data, so when I import readings I have to auto-assign a tag (that’s why they come in as “Before Breakfast”). You’re right that imported entries aren’t editable today — but I’m adding manual edit support for imported readings, and you’ll see it in the next update.Really appreciate you taking the time to share this. If you ever need anything, you can always reach me through the in-app Support — I’m happy to help anytime. 🙏

Doesn’t help much to monitor

Simple to use. Don’t give a full picture to see the changes. The graf is too simple and open to interpretation. And you have to pay 4.99 on the second use of this program in order to continue to use it. In my opinion, tracking weight and having the option to track A1C, would benefit this program. I will use it for 1 month to see a better presentation of the graph. But it feels already that something is missing there.

Developer Response
Thanks for your honest feedback — it’s truly appreciated!The graph view has recently been improved for better clarity and insight. A1C tracking and weight logging are also on the roadmap based on user suggestions like yours.Hopefully the updates make a difference during your trial month. If the improvements meet your expectations, an updated 5-star review would mean a lot! 🌟
