Vakaa and Glucose Buddy both help people record blood sugar readings, but they are built around different assumptions.
Glucose Buddy is a broad diabetes tracker. Its US App Store listing describes blood sugar, medication, A1C, weight, carb intake, meals, insulin, activity tracking, Apple Health integration, Dexcom integration, reports, and Premium features.
Vakaa is narrower by design. It is a manual blood sugar logbook for iPhone: fast entry, visible units, meal timing, paired before-and-after readings, recent trends, and doctor-ready exports.

Quick answer
Choose Glucose Buddy if you want one app for glucose, carbs, meals, medication, insulin, activity, Apple Health, Dexcom integration, and broad diabetes tracking.
Choose Vakaa if you want a quieter manual logbook with no account requirement for core logging, local-first storage, no ad-tracking business model, and fewer required decisions during each save.

Where Glucose Buddy wins
Glucose Buddy wins if you want breadth. Its listing describes a food database, medication tracking, insulin tracking, weight, activity, Apple Health, Dexcom integration, A1C trends, advanced graphs, custom reports, custom tags, and Premium features.
That breadth can be useful for people who want to connect meals, carbs, insulin, and glucose in one place. It can also help users who already have a Glucose Buddy habit and need historical continuity.
The review footprint is also much larger. A large, long-running app has more public feedback and a longer product history than a newer focused logbook.
Where Vakaa wins
Vakaa wins when the problem is simpler: “I need to write down my blood sugar reading quickly and review the pattern later.”
The app is designed around the minimum useful entry: glucose value, timestamp, visible unit, and one meal-timing tag. Extra details are optional. That matters for people who are not counting carbs in the app, not logging insulin, and not trying to run a full diabetes dashboard.
Vakaa also keeps data local-first. It does not require an account for the core logbook, and the product promise is explicit: no ads and no third-party data sharing with the developer. Full JSON backup remains free because raw user data should not be trapped behind a paywall.
Which is better for manual fingerstick logging?
For manual fingerstick logging, the answer depends on how much context you actually need.
If your clinician asked for glucose plus carb notes, medication, insulin, weight, and activity, a broad tracker like Glucose Buddy may fit that workflow. If your clinician asked for a readable blood sugar log with fasting and post-meal context, Vakaa is likely closer to the workflow.
The point is not to collect the most fields. The point is to keep a record you can maintain. A manual log only becomes useful if you can keep using it after the first week.
That tradeoff is especially important for caregivers and older adults. A broad tracker can be useful when one person manages many details, but it can also make the repeat entry flow harder for someone who only needs to record a meter value and timing label.
Pregnancy and prediabetes use cases
Pregnancy logging often centers on fasting plus post-meal checks. Prediabetes logging often happens in short sprints to compare fasting and after-meal patterns. Both use cases can be damaged by a heavy entry flow.
Vakaa is intentionally shaped around those lighter routines. The gestational diabetes log guide explains the pregnancy version. The conversion chart for mmol/L to mg/dL helps if your meter, clinician paperwork, or online references use different units.
Bottom line
Glucose Buddy is a stronger fit if you want a large diabetes tracker with carbs, medication, activity, integrations, and broader reporting. Vakaa is a stronger fit if you want manual glucose logging to stay fast, private, and focused.
