This app hasn’t received enough ratings or reviews to display an overview.
Track anything you want — and keep your data safe.
• Custom Trackers — add your own things to track (nail length, wheel distance, mood, medication… anything you measure), log them in a tap, and chart them over time. This one came straight from your survey.
• Backup & Restore — save everything to a single file you keep, and bring it all back on a new phone or after a reinstall. Free, because your hamster's history should never sit behind a paywall.
• Cold-snap & torpor warnings — now free. When a cold night could put your hamster at risk, you'll see a warning right on your home screen, wherever you are. (Premium adds the automatic night-before alert.)
• Reminder Check-Up — a one-tap way to confirm your reminders are actually set and will fire.
• More reliable iCloud sync behind the scenes.
Thank you for shaping HammyNest — keep the ideas coming in the survey.
