Prepare for the German plant-protection knowledge exam and for the German "Giftschein" (poison and hazardous-substances knowledge exam) with explained plant protection questions, Giftschein questions with source references, mistake review and timed practice simulations. Part of the content is usable without a purchase; unlock the rest with one purchase, without a subscription. The learning material and questions are in German. This independent theory trainer supports preparation for application/advice or sale/supply, including agriculture and horticulture. GIFTSCHEIN (NEW IN VERSION 1.7) Besides the plant protection content (526 questions), the app contains the question catalog for the knowledge exam under section 11 of the German Chemicals Prohibition Ordinance (ChemVerbotsV): 593 questions in 15 topics. Part I General (324 questions) includes chemicals law, the Hazardous Substances Ordinance, hazardous-substance basics, hazard control and first aid, and penal and administrative-offense law. Part III Plant protection products (269 questions) includes properties, toxicology, environmental effects and active-substance groups. Questions and answer options appear unchanged in the wording of the Joint Question Catalog of the German States (BLAC, version of January 28, 2026, legal status October 31, 2025), in German only. The Giftschein practice simulation asks 20 questions per part; as an in-app practice threshold, a part counts as passed with at least 11 correct answers. "TODAY" HOME SCREEN Exam readiness for plant protection, a countdown to your exam date (optional) and a daily round of reviews and new questions. Unsure? Tap "Just guessed?" and the question comes back. PLANT PROTECTION LEARNING AREAS - legal basics and obligations - integrated plant protection - products, labeling, authorization and conditions - risks for people, animals and the environment - safety measures, emergency response and first aid - application technology and equipment - documentation and records FEATURES - quiz questions with explanations (plant protection) or source references (Giftschein) - read-aloud for questions and answers, plus explanations in plant protection - timed practice simulations with evaluation - study profiles for application/advice and sale/supply - practice previously downloaded topics offline - progress tracking and review of missed questions - AI study help with in-app reporting for responses IMPORTANT DISCLAIMER The app is independent and is not provided by an authority, chamber, examination body or recognized training provider. It is not an officially recognized course, does not issue a certificate of competence or a Giftschein, and does not replace a course, practical instruction or exam. The Giftschein part is for practice with the published question catalog; it is not an offering of the BLAC. It does not promise matching specific exam questions, an official exam flow or a successful result. Content may contain errors and is not legal advice or a concrete product, mixing, dosage or application recommendation. Current law and the applicable authorization, labeling and conditions remain authoritative. ONE-TIME PURCHASE Legal basics and integrated plant protection are free to practice, including explanations for the questions. One Giftschein topic (basics of chemicals law) is usable as a sample without a purchase. Plant Protection Complete adds five more topic areas: products, risks and hazards, application technology and equipment, emergency response and first aid, and documentation. It also includes the complete Giftschein part with practice simulation, the timed plant protection practice simulation with evaluation and the AI study assistant. You can download premium topics too and practice offline. The Giftschein needs no additional purchase. Unlock once, without a subscription. The store shows the current price before purchase. Previously purchased content can be restored through purchase management.

Verdict

The call

The clearest difference is in-app purchases: Adinkra at none against Plant Protection Study's 1. Plant Protection Study's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, review sentiment and ads there is nothing between them.
