Make everyday care easier with TailNotes. Keep a diary for your pets, save notes and documents, track weight, and organize care reminders.

Both caregivers can update the shared diary and feeding plan. Feeding marks help you check whether a meal has already been recorded. Create pet cards and missing-pet posters to share the information you choose. TailNotes Plus includes multiple pets of your own, inviting a caregiver and exporting pet cards. Your first pet’s diary, weight, reminders, feeding plan and natural-food calculator remain free. Accepting an invitation is free. Saved pets and existing shared access remain available after your subscription ends. Plus offers weekly, monthly and yearly auto-renewable subscriptions. Prices are shown in the app for your region.

Verdict
The clearest difference is ads: Pet Journal at none against Crittr's shown. Crittr's advantage is update cadence (weekly vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
