Pegverse

Pegverse is the calm, beautiful companion for every aquarist. Keep your water thriving, your residents healthy and your care routine on track — all in one fully offline app built for the fish-keeping hobby. Crystal-clear water quality at a glance. Log pH, temperature, ammonia, nitrite, nitrate, general hardness and carbonate hardness for each tank. Pegverse evaluates every reading against safe ranges specific to your water type — Tropical Freshwater, Coldwater, Planted, Shrimp, Cichlid or Nano Reef — flagging each parameter as OK, Caution or Danger instantly. Automatic trend charts reveal whether values are rising, falling or stable so you can act before small shifts become serious problems. Know your residents. Know your limits. Keep a full census of every fish, plant and invertebrate in each tank. A built-in stocking calculator shows whether you're understocked, well-stocked or overloaded. Browse the offline species catalog — 15 popular species with photos, minimum tank sizes, ideal water parameters and expert care notes — and add them directly to any tank. Never miss a care day. Set recurring schedules for feeding, water changes, filter cleaning, fertilising and water testing. Pegverse surfaces what is overdue, due today and coming up, then tracks your care streak so you stay consistent. Every tank card comes alive with animated bubbles, water shimmer and drifting fish. Photograph tanks and residents with your camera or choose from your library, then generate a shareable tank card saved straight to your photo library. No account needed, no data collected, no ads — everything lives on your device, fully offline.
