Colony Manager
Read full descriptionHide full description
Colony Manager is a private tool for running a laboratory-animal colony: mice, rats, and zebrafish, in one place, on your iPhone, iPad, and Apple Watch. It is built for researchers and animal-facility staff who would rather spend their time on the science than on spreadsheets, and it keeps your records with you, not on anyone else's server. WHAT YOU CAN TRACK - Animals and housing: cages and tanks, with a visual rack and system view. Zebrafish are handled as counted group stocks, with the option to pull out individuals when you need them. - Breeding: pairs, litters, clutches, weaning, and pedigrees. - Genetics: genotypes and zygosity. - Procedures and project licences, so you can see what is allowed and what has been done. - Welfare scoring, with humane-endpoint prompts. - Alerts and reminders, gathered on a Today board so nothing is missed. TOOLS - Dosing and breeding calculators, with a clear veterinary disclaimer: they are aids based on published defaults, never a substitute for your own judgement and your veterinarian. - Reference tables for species data and EU Annex VIII severity categories, with sources. - CSV and PDF exports, and reports that assist with EU and German record-keeping (Directive 2010/63, TierSchVersV, ALURES). The app assists with compliance; it does not certify it. PRIVATE BY DESIGN - No account, no adverts, no tracking, no third-party services. - Your data stays on your device and syncs only through your own private iCloud. The developer never sees it. - Works offline. Camera is used only to scan barcodes and attach photos. ALSO INCLUDED - An Apple Watch companion and Home Screen widgets for at-a-glance status and reminders. Colony Manager is completely free, with no subscriptions and no in-app purchases. Important: Colony Manager helps you keep your own records and reports. It is not veterinary, legal, or regulatory advice, and it does not certify compliance. Dosing values, welfare scores, and reference content are aids; verify them against current authoritative sources and your veterinarian, and always follow the law and your institution's requirements where you work.

Verdict
The clearest difference is ads: Colony Manager at none against TreeChart's shown. TreeChart's advantage is iOS requirement (11.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
