hermit crabs & isopods
Monitor your crabitat and isopod colonies. Track enclosure conditions, log care activities, watch colony growth, and set smart reminders.
Everything you need to care for your colonies
Enclosure manager
Set up multiple enclosures with photos and target conditions. Track each crabitat or isopod bin separately with dedicated temperature and humidity targets.

Watch your isopod colonies grow over time. Track population counts, gravid females, recent babies, and see growth trends from your starting count to today.
Smart reminders
Set schedules for feeding, misting, deep cleaning, shell rotation, and water changes. Never miss a care task with customizable reminders for each enclosure.
Complete care log
Log every care activity — feedings, misting, water changes, observations, and more. See your complete care history at a glance with timestamps and notes.

Frequently asked questions
Is CrabPod free?
+
Yes, CrabPod is completely free to download and use. All features — enclosure management, environment tracking, colony growth, reminders, and insights — are included at no cost.
Can I track multiple enclosures?
+
Absolutely. Add as many enclosures as you have — each with its own temperature and humidity targets, pet list, care log, and environment readings. Switch between them easily from the main screen.
Does it work for tarantulas and scorpions?
+
For tarantulas, scorpions, mantids, and other individually-kept invertebrates, check out InvertMate — our companion app built specifically for tracking individual pets with molt logging, weight tracking, and species library.
How does colony growth tracking work?
+
Log your starting colony count when you set up an enclosure. Then update the population periodically — CrabPod calculates growth rate, tracks gravid females, recent babies, and shows your colony’s growth trajectory over time.
Is there an Android version?
+
CrabPod is currently available on iOS (iPhone and iPad). An Android version is being considered based on demand.
Is my data stored securely?
+
All your data is stored locally on your device. Your enclosure information, readings, and care logs never leave your phone unless you choose to export or back them up yourself.
