## What is Bolo?

Bolo is the type 1 diabetes diary you'll want to open every day. Glucose, meals, insulin, medications and appointments in one clear, cheerful place, on your iPhone and Apple Watch.

LIVE GLUCOSE
• Readings from your Dexcom account every 5 minutes (Dexcom Share, like the Follow app), from Apple Health or entered by hand.
• Low, high and no-data alarms, even with the app closed if you turn on always-on alerts.
• Widgets, a Live Activity on the Lock Screen and Apple Watch complications.
• The Ribbon: the chart that stays straight while you're in range and shows at a glance when you go up or down, with meals and boluses in place.

MEAL DIARY
• Carbs and sugars in a few taps: barcode, label reading and dishes you build, like flatbreads, pizza and sandwiches.
• Type "flatbread with sausage and peppers" and Bolo builds the dish with the grams.
• Hypo sugars logged with one tap.

EATING OUT AND FAST FOOD
• McDonald's Italy products and meals with the values the chain publishes: pick burger, size, side and drink and Bolo adds up the carbs.
• Pub, steakhouse, Tex-Mex and Chinese restaurant dishes: wings, nachos, onion rings, burritos, spring rolls and many more.

INSULIN AND MEDICATIONS
• Boluses and basal logged in a moment, with a basal reminder.
• Informational warnings about medicines that may raise or lower your glucose, with sources. They invite you to keep an eye on your readings and talk to your diabetes team.

CHARTS AND REPORTS
• Time in range, average, variability and estimated HbA1c from today to 90 days.
• Daily and weekly summaries and a PDF to bring to your appointment.

MEDICAL RECORD AND SENSOR
• Visits, reports read from a photo, HbA1c over the years, documents.
• Sensor days left, wear sites and reminders before it expires.

RECIPES AND SHOPPING
• Over 300 recipes with carbs per serving, a week plan and a shopping list you can send to the Manca! app.

YOUR DATA STAYS YOURS
• Your diary stays on your iPhone. No account, no ads, no data sold.
• Encrypted backup with a password only you know.

IMPORTANT
Bolo is not a medical device. It logs, shows and warns, but it does not calculate or suggest insulin doses and does not tell you how to correct your glucose. It does not replace your sensor's alarms or your doctor's advice. Dexcom is a trademark of Dexcom, Inc.; Bolo is not affiliated with or endorsed by Dexcom.

## Version history (last 5 releases)

### 1.0.4 — 2026-10-16

What's new in 1.0.4
• Fix for pizza by the slice: with ¼, ½ or ¾ of a pizza, each ingredient under “On the plate” now shows the grams and carbs of your share, matching the total. It used to show the whole pizza's; the total was already right.

### 1.0.3 — 2026-10-14

What's new in 1.0.3
• Pizza by the slice: when you build a pizza you can pick ¼, ½, ¾ or a whole one, and the carbs follow the slice. A pizza al taglio slice now has its own toppings, not those of a whole pizza.
• Bolo also understands fractions when you type the dish: “1/4 pizza with porcini and arugula”, “half a piadina”, “three quarters of a pizza”.
• Fix: before, a quarter of a pizza could come out with the carbs of half a pizza. If you saved a pizza among your foods, open it again and pick the right slice.

### 1.0.2 — 2026-10-13

What's new in 1.0.2
• iPhone Duo: when it's open, Bolo uses the whole screen. Tabs move to a side bar and every page splits in two along the fold: Today shows your glucose on the left and the ribbon always visible on the right; Diary shows your day and its chart; Charts shows the numbers and the graphs; Recipes shows the cookbook and the open recipe; You shows the list and the chosen page. Closed, it's the Bolo you know.
• Fix: a product with no nutrition values (for example from Open Food Facts) could make the app close every time it opened. Now it opens, and all your data stays where it was.

### 1.0.1 — 2026-10-12

New in 1.0.1
• Bolo in the car with CarPlay: your glucose on the Dashboard (with the Live Activity on), alarms at the bottom of the car screen and the new "Big glucose" widget.
• Siri: "Hey Siri, glucose in Bolo" and it tells you out loud, without touching your phone.
• On the bolus sheet, at the top: current glucose with its arrow, the previous reading and the change over 15 minutes.
• Bolus before eating: set the meal time up to 1 hour ahead and Bolo reminds you to eat.
• Charts: the "In range" card day by day, coloured by how much time you spent in range.
• Apple Watch: your glucose big in the Smart Stack.

### 1.0 — 2026-10-11
