Fern Hollow

Fern Hollow is a pet journal designed for people who care about keeping their animals healthy and well-fed. The app gives you a quiet, structured space to log daily meals, portion sizes, and body weight over time for every pet you have.

You can add multiple pets and maintain separate records for each one. Feeding logs include meal times and portion details, so you can spot patterns and stay consistent with routines. Weight history is recorded with dates and displayed as a trend, helping you notice gradual changes that might otherwise go unnoticed.

Everything runs locally on your device. No account needed, no sync, no server. Your data stays with you.

The interface comes in four themes — two light and two dark — so you can pick the look that feels comfortable. You can also set your preferred time format (12-hour or 24-hour) and choose which day your week starts on.

Fern Hollow is built for anyone managing the daily care of one or more pets who wants something simple, reliable, and private.
