💧 One-tap sessions
Volume, site and how it went — prefilled from your vet's plan. A home-screen widget logs it without opening the app.
🔄 Site rotation
Four zones on a simple cat outline. The app remembers which side you used and suggests the next one.
🧴 Bag countdown
Know how many sessions are left in the bag before it runs out on a Sunday night.
📈 Bloodwork trends
Creatinine and SDMA charted over time on IRIS reference bands — context for the conversation with your vet.
📝 Daily check-ins
Weight, appetite, vomiting, drinking and litter, plus the medications your vet prescribed.
📄 Vet report
One tap turns weeks of notes into a tidy PDF: fluids given, weight trend, symptoms and labs.
Private by design
Everything stays on your iPhone. No account, no cloud, no analytics — it works in Airplane Mode. Export your data as a CSV whenever you like.
Pricing
Logging fluids, check-ins and medications is free and unlimited for one cat. SubQ Fluids Premium adds the vet report, bloodwork trends, full history, multiple cats, medication reminders and the home-screen widget — $5.99 a month or $34.99 a year with a 7-day free trial.
