What It Is

Ketologger is an iOS app for logging ketone and blood glucose readings. It has a very specific focus: helping users enter ketone/glucose measurements, add notes, view history, and visualize trends with charts. The available content does not mention any generative AI, predictive models, or intelligent recommendation features, so it is more accurately described as a health data logging and visualization app rather than an AI application.

Core Capabilities

The product centers on data entry and calculation. Users can enter blood glucose in their preferred unit, and the interface automatically handles unit conversion. Ketone and glucose readings can be viewed separately or together. When combined, Ketologger matches the closest readings by date and time and calculates G:K / GKI. When G:K is less than or equal to 1, it is highlighted in green, making key states easier to identify quickly. Charts are displayed consistently in mmol/L, with mg/dL glucose data automatically converted when needed.

Data Import, Backup, and Privacy

Ketologger supports importing specific CSV files generated by the Keto-Mojo app, as well as its own database snapshot files in .kl format. For export, it supports CSV and Reading Snapshot. Through the iOS share sheet, users can transfer files between devices via email, messaging apps, SMS, or cloud services such as Google Drive. It also automatically creates a database snapshot when leaving the app and can restore readings from backups. Note that the CSV format requirements are fairly strict: Separated CSV cannot be re-imported, and unknown formats may fail. If an import fails, users can choose to anonymously upload a sample to help with troubleshooting. The available content does not provide a full privacy policy, encryption details, or medical compliance information.

Pricing and Chinese-Language Support

The captured content does not mention pricing, subscriptions, free trials, or payment methods. It also does not state whether the app offers a Chinese interface, Chinese documentation, or Chinese customer support. No public API is mentioned; integrations appear to be limited mainly to file-level import/export and the iOS sharing mechanism.

Pros, Cons, and Who It’s For

Its strengths are a focused feature set, simple data entry, automatic GKI/G:K calculation, chart visualization, and local backup/migration support. Its limitations include an explicitly iOS-only positioning, limited format compatibility, no stated AI capabilities, and insufficient disclosure around pricing and privacy. It is best suited for ketogenic diet users who already use Keto-Mojo or manually track ketone and blood glucose readings. For users in China, the available content does not clarify website or App Store availability, nor the accessibility of cloud services such as Google Drive in mainland China. If Google Drive is required, sync and sharing may be restricted; email, iCloud, or local file transfer may be more practical alternatives.
