Most tools pick a side. KeeperOS fits both, and grows between them.
One gecko and a notes app became five animals and three schedules, and you can't remember if you fed Noodle on Tuesday. Generic pet apps don't get reptiles; spreadsheets fall apart as you grow.
Every animal, enclosure, and care task in one place, built around real reptile husbandry. Water, feed, weigh, clean, mist, UV: due and overdue at a glance on a visual map of your actual room.
Clutch dates on a whiteboard, feeding on a spreadsheet, sales in your DMs. Breeder software is clunky or built by people who've never cut a rack, and hobbyists who scale up have to start over on a new tool.
Racks, clutches, incubation with temp tracking, hatchlings, and sales: the full operation, built by breeders. Feed a hundred hatchlings in a hundred taps. Same app you kept your first gecko in. No restart.
Other apps make you find the animal. KeeperOS puts it where it lives.
Find the animal by ID → open its record → open a form → type → save → back → repeat ×100. Care day becomes data entry.
Your setup is the interface. Tap the enclosure or the tub in front of you. The animal, its schedule, its history, its feeder and scent are already attached to the spot it lives in. Care day stays care day.
Keep
Enclosures, care schedules, feeding, growth. Every animal and every care task on a visual map of your actual room.
Grow
Add a rack when you need one. Same app, more capacity. Track more animals and stay on schedule as you scale.
Breed
Clutches, incubation with temp tracking, hatchlings, and sales. The whole season in one place, when you grow into it.
One snake or a hundred hatchlings: see your room the way it sits, tap to log.
