DragonSphere
Read full descriptionHide full description
DragonSphere makes caring for and managing reptiles and invertebrates simple and reliable. Designed specifically for keepers and breeders, the app lets you organize all essential animal data in one place — from names, photos, morph, and feeding schedules to birthdays, sex, feeder types, and species. Document feedings, sheds, and weight and size measurements, complemented by reminders for feedings and cleanings so nothing gets forgotten. Manage your terrariums and assign animals and cleanup crew. Animals can be exported and imported with all their data via AirDrop to other devices (Premium). Your data is stored locally on your device and optionally synced securely to your private cloud — no registration required. The free version supports up to seven reptiles and invertebrates with all core features. Available in 38 languages. Built by an experienced breeder, DragonSphere gives you maximum control and privacy: your data belongs to you. With DragonSphere Premium you unlock advanced features that make keeping and breeding reptiles and invertebrates significantly more efficient — with an unlimited number of animals and tools that keep you on top of your collection at all times. Log feedings quickly by scanning a QR code or via multi-select for entire groups. Manage your terrariums along with their assigned animals and cleanup crew. Cost tracking splits a terrarium's operating costs across the animals in it and shows what each animal costs to keep. For breeders, Breeding Management plans pairings and manages clutches, events, and hatchlings in dedicated projects. For inspections by the authorities, create breeding records as a PDF — for your entire collection or just your breeding animals. Structured Genetics records each animal's morphs by inheritance type and gene locus, and the Gene Calculator shows the expected offspring of a pairing with probabilities — right in a clutch or as a quick calculator from the home screen. Get species data sets straight from the mf-cornsnakes.at catalog, map them to your species and export your own species as a .dsspecies file. Finally, saving and sharing handle the rest: import data from CSV or Time2Feed, share individual animals as .dsanimal files via AirDrop, or create a complete backup including all photos as a .dsbackup file. DragonSphere Premium offers professional tools for structured animal management with full control and privacy over your data. -------------------- What's New -------------------- Version 1.6.1 · Breeding records · Operating costs per animal · More improvements Version 1.6 · Reminders switchable one by one · Health check · Genetics from the Catalog · Merge and export species · Feeder details · Frozen feeders · Handover card as image · Price on the animal Version 1.5 · SoloPlan sync master switch · Feeder stock counting · Genetics dataset import · Birth date precision · Improved imports & backups · Many fixes Version 1.4 · Breeding Management · Structured Genetics · Gene Calculator · iPad layout · Backup with photos · Bulk export Version 1.3 · Enclosures · Invertebrates · Multi-select & bulk actions · Redesigned animal details · SoloPlan integration Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is iOS requirement: TerrOS at 15.0 against DragonSphere's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.
