Der LineUp Randomizer stammt direkt aus der Praxis – entwickelt von einem polizeilichen Diensthundeführer und Ausbilder, der täglich mit Spürhunden arbeitet. Sie richtet sich an alle, die realitätsnah und methodisch sauber trainieren möchten: • Diensthundeführer in Polizei, Zoll und Sicherheitsdiensten • Trainer von Rauschgift-, Sprengstoff- und anderen Spürhundesparten • Ausbildungszentren, Hundeschulen und Trainingsstätten • ambitionierte Hundetrainer, die ihre Arbeit objektiv und professionell gestalten wollen Warum Zufall im Training entscheidend ist Wiederholte Zielpositionen oder unbewusste Hinweise führen zu „Bias“ – der Hund lernt Muster statt Geruch.

Design & Benutzererlebnis • Modernes Tactical-Blue-Design – klar, praxisnah, kontraststark • Große, übersichtliche Bedienelemente – auch mit Handschuhen bedienbar • Haptisches Feedback bei jeder Generierung Datenschutz Keine Anmeldung, keine Werbung, keine Datensammlung. Die App funktioniert komplett offline – ideal für Behörden und Trainingszentren. LineUp Randomizer – Trainiere fair. Trainiere ehrlich. Trainiere randomisiert.
Puppy Tracker

Puppy Tracker makes it easier to care for a litter from birth until the puppies leave for their new homes — or to follow the growth of one puppy over time. Choose the tracker that fits you: manage an entire litter with quick weighing rounds, or use the dedicated single-puppy view for weight history, feeding notes and an estimate of how big your puppy will get. For litters, record every puppy's weight in one round and see the 24-hour and 48-hour changes at a glance. Clear labels show who is on track, who is growing slowly and who is losing weight, so you know right away who needs extra attention. For one puppy, record weights at flexible intervals, compare them with typical growth for their size and see their expected adult weight. Weigh in grams and kilograms, or in ounces and pounds — whatever you're used to. Built for breeders, new litters and puppy owners, Puppy Tracker stays calm and simple even when you need to enter many weights at once. Features: • Track a litter or one puppy • Create and manage multiple trackers • Add puppies with collar colors, names, birth weights, dates of birth and other details • Record weighing rounds for the whole litter • See 24-hour and 48-hour changes, and who needs attention • Follow each puppy's weight history and growth chart • Compare the whole litter in one chart • Expected adult weight and typical growth for single puppies • Care: puppy feeding rounds, mother feeding times and a health log for deworming, vaccinations and vet visits • Keep a feeding log with times and notes for one puppy • Add litter and puppy notes • Import weight logs from Excel, Numbers or Google Sheets — or paste the cells straight in • Export weight logs for sharing or backup • Grams and kilograms, or ounces and pounds • Modern or classic design, in light or dark mode • Use the app in English, German, Spanish or French Already tracking litter weights in a spreadsheet? Import it — or copy the cells and paste them in — and continue in Puppy Tracker. Premium is available as a one-time purchase and unlocks unlimited weighing rounds, litters, single-puppy trackers and puppies. The adult weight estimate is based on typical growth curves and is not veterinary advice.

Verdict
