+++ Dyslexia Quality Award Winner 2015 +++ This entertaining and educational matching game app helps you practice your German grammar and spelling in a fun way. Whether you need to brush up on parts of speech, conjugation or declination, tenses and types of sentences - no matter what you need, the various grammatical areas can be combined with each other and practiced. With one click, the appropriate themes are chosen, easy as pie, and you can start right away. Matching pairs must be found, either by purely assigning terms to the proper categories (intelligent = Adjektiv | Ich werde spielen = Futur 1) or as a concentration-enhancing matching game. THE GRAMMATIK DUELL HELPS YOU PRACTICE YOUR KNOWLEDGE IN A FUN WAY Both the number of card pairs and the number of players are, of course, variable. Depending on your wishes, the cards can be read aloud, and the length of time in which the cards are revealed is adjustable. The difficulty level of the app increases with the number of card pairs and the chosen area of grammar. It is aimed at all students who are not yet entirely comfortable in their use of grammatical terms or who want to practice for their next grammar lesson in a fun way. You can also work on improving your spelling. STRONG MOTIVATION TO LEARN GRAMMAR On your own in a race against time or against a challenging opponent - who will use the fewest number of moves to find the matching pairs? Who will collect the most stars and end up the winner in this grammatical duel? The beautiful visual presentation of the playing cards, the acoustic sounds of success, the pleasing voice that reads aloud, the game variations, the pedagogically sophisticated content and the strict limitations of only relevant content make this app a truly worthwhile learning aid. The Grammar Challenge makes learning grammar fun! PEDAGOGICAL BENEFITS OF THE APP: • Self-explanatory • Concentrates on the content without distractions • Motivates with a reward system • Practice mode • Boosts concentration skills • Selectable levels of difficulty • Selectable number of card pairs • Selectable read-aloud function • Selectable areas of grammar • “Assignable” game variations • Beautiful, relevant graphics • No in-app purchases • No online connection necessary • Learning psychology tested and approved TECHNICAL AND PEDAGOGICAL KNOW-HOW COME TOGETHER IN THE GRAMMATIK DUELL The idea for this app with regard to its content was created by licensed pedagogue Uta Reimann-Höhn (www.lernfoerderung.de), who has published numerous books as an expert on education and upbringing, and who has been the editor-in-chief of “Lernen und fördern mit Spaß!” (“Learn and Grow with Fun!”) since 2006. The idea was implemented by Jan Essig (www.janessig.com), a designer who has made a name for himself with his high-quality educational apps “Adventure Playground” and “Preschoolers ABC Playground” and has won numerous awards.

A few good minutes a day for your mind. Fifteen small, calm games and one daily Challenge. Play a little, then put the phone down. My son and I made Grandmind for Grandma. We saw her days slipping away into endless scrolling and wanted to give her something better to reach for: short games with big pieces, clear words and nothing to rush. THE CHALLENGE Swipe each piece to the side it matches. Every so often a twist changes what to match. Three misses end the run, and each right answer scores more as the game gets harder. Compare with friends on the Game Center leaderboard. FIFTEEN GAMES IN FIVE AREAS • Memory: Remember, Repeat, Notice • Focus: Search, Filter, Follow • Speed: React, Compare, Scan • Logic: Predict, Plan, Sort • Spatial: Mirror, Rotate, Copy Every game opens with a short moving demo, so you see how to play before you start. Choose a try of 1, 3 or 6 minutes. Games step up after two right answers and ease off after a miss, so they meet you where you are. SEE HOW YOU'RE DOING Stats show your streak, your time played, a calendar of the days you played and a chart of all five areas, with your gains marked against your own earlier tries. EASY FOR EVERY AGE • Big pieces and large, clear text • Relaxed timing gives you twice the time to look • Colour patterns if colours are hard to tell apart • Screen limit: apps you choose, like social media, lock after your daily time until you've played today's five • Gentle reminders, and one missed day a week won't break your streak • Light and dark themes, and four app icons to pick from • Your progress syncs between iPhone and iPad with iCloud • No ads FREE AND PRO Five games are free every day, one from each area, and they change daily. The Challenge, Stats and leaderboards are always free. Grandmind Pro opens all fifteen games, any day. Choose a yearly plan, or buy Lifetime once. Payment is charged to your Apple Account when you confirm. The yearly plan renews automatically unless you turn it off at least 24 hours before the end of the current period. You can manage or cancel it any time in your Apple Account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://grandmind-1eeba.web.app/privacy Grandmind is for fun and daily practice. It isn't a medical test or treatment.
