Consequently, every successful business needs a modern application or web site, which will provide customers with a better experience. This thesis provides an implementation of such a solution for bouldering gyms. Using a QR-code scanner integrated into iPhones, it allows everyone to track their results easily, compare them with others, and find new climbing friends. Owners of the gyms cansee in-depth statistics as well as the problems currently occurring about their properties and have all the necessary data stored in a database. It is all accompanied by an intuitive UI, and UX arranged to satisfy even the pickiest users. iv Keywords iOS, Swift, iPhone, QR-Code, boulder, climbingg, app, UI, UX v Contents 1 Introduction 1 1.1 Thesis goal ..........................1 1.2 Structure of the thesis .....................1 2 Bouldering 3 2.1 Hangar Climbing playground by Adam Ondra .......3 3 Used software, libraries, and design patterns 5 3.1 iOS ..............................5 3.1.1 Apple ID . .6 3.2 Swift ..............................7 3.2.1 CocoaPods . .8 3.2.2 SnapKit . .9 3.2.3 PromiseKit . 10 3.2.4 R.swift . 11 3.3 XCode ............................. 11 3.4 Firebase Realtime Database .................. 12 3.5 Model View Controller pattern ................ 13 4 Development process 15 4.1 Coming up with the idea ................... 15 4.1.1 Similar Apps . 15 4.2 Functional and non-functional requirements ......... 16 4.3 Prototyping .......................... 17 4.4 UI and UX design ...................... 19 4.5 Back-end ............................ 20 4.5.1 Security rules . 22 4.6 Implementation ........................ 25 4.6.1 Building UI . 26 4.6.2 Firebase integration . 29 4.6.3 Applying MVC pattern . 30 4.6.4 QR Code scanning . 30 4.6.5 Communication between climbers . 30 4.7 Transformation of the data .................. 31 4.8 Testing ............................. 32 4.9 Impact of COVID-19 ..................... 32 vii 5 Conclusion 35 Bibliography 37 viii List of Figures 3.1 The lifecycle of an iOS app [3] 6 3.2 The lifecycle of a view controller in an iOS enviroment [4] 7 3.3 Rating of XCode on AppStore [8] 12 3.4 Model View Controller pattern [10] 14 4.1 The rating of Vertical-Life: Outdoor and Indoor Climbing [11] 16 4.2 Difference between a wireframe login page (left) andthe final look (right) 18 4.3 Icon representing boulders throughout the application with grade and color showed 19 4.4 Icon for indicating the evocation of QR-code scanner (left) and table cell for representing boulder (right) 19 4.5 Final screen showing a menu (left) and the selected item fetching the info from the website (right) 20 4.6 Model of a SQL database used for this app 21 4.7 Screen showing current rankings of the climbers always for certain category.

They are used all the time, and in developed countries, about 75% of all people own smartphones [1]. People say that they are utilized too much, but it is clear that they help to save lives in areas such as healthcare and are making our lives easier in many ways, for example, tracking progress in individual sports. Mobile phones bring new opportunities for the development of applications. 1.1 Thesis goal The main goal of the thesis is to develop an iOS application for wide adaptation in bouldering gyms. During the development, the solution was consulted with the end-users to suit all their needs. The main functionality includes a QR Code scanner, an overview of the gym for both gym owners and climbers in the gym, provided with intuitive user interface(UI) and user experience(UX) design. 1.2 Structure of the thesis The text is structured into Introduction, after that an explanation of bouldering, and a short presentation of the gym who will be using it, its current solution, and the main advantages of using this product. The third chapter explains all the technologies and libraries used. In the fourth chapter, the whole development process is introduced from the initial idea through communication with the client and graphic design to the implementation process. After that, the process of trans- forming the data from Google spreadsheet to database is explained, and the impact of world pandemic COVID-19. In the last chapter, the conclusion is included with the description of the current state of the application. 1 2 Bouldering Bouldering is a type of climbing performed on small rock formations or indoor artificial walls not higher than 4-5 meters. Climbers donot need to use ropes or any other equipment besides climbing shoes and a chalk bag. If they fall, they land on a mattress. Lately, a lot of indoor bouldering walls are being built, and this sport is becoming more and more popular. The fact that contributed a lot to the bouldering’s popularity is, it will be part of the summer Olympics games for the first time. One route on a wall is called a boulder or a boulder problem. The boulder problems range from very easy to extreme, which only a few people in the world can climb. A specific grading system was developed, and although there are different types in Europe, the most widely used is called “Font grading“, where the most straightforward problem is grade 3. With increasing difficulty, the numbers increase. Starting from 5, each grade has its subgrade marked with capital letters A, B, C. An additional + sign may be added to show it is a little more complicated but not hard enough for the higher grade. The scale goes from 3, 4, 5A, 5B, 5C, 6A to 8C+, which is currently the hardest grade climbed. Routesetters build indoor boulders; each one has a specific color, type of holds, and a particular style. The styles include overhangs, slabs, or jumping from one hold to another, called dyno. 2.1 Hangar Climbing playground by Adam Ondra Hangar Climbing playground by Adam Ondra is the biggest and most modern bouldering wall in the Czech Republic, located in Brno, which will use this application in order to improve their customer service. Every month they put up 30 new boulders and competition is held through-out, it is called a Hangar-challenge. The gym has a hard time keeping track of the results as they keep them in Google spreadsheets. Users find it confusing as well, and anyone of the users can delete all the data. Information about all the boulders is on paper, and the papers can get lost or destroyed easily. Climbers now have minimal options of keeping track of which boulders they climbed and how many attempts it took them. Also, they cannot see if 3 2. Bouldering there are new boulders or their favorite ones have been put down. All these problems will be fixed once the gym opens after the COVID-19 lockdown and starts using the application. 4 3 Used software, libraries, and design patterns This chapter is dedicated to introducing all the technologies that have been used. Software from Apple Inc. and third-party libraries are included. It provides a brief description with simple examples. 3.1 iOS iOS (formerly iPhone OS) is a mobile operating system created and developed exclusively by Apple Inc. for its hardware. It is the operating system that presently powers all of the company’s mobile devices, including the iPhone and iPod Touch; it also powered the iPad before the introduction of iPadOS in 2019. It is the second most popular mobile operating system globally after Android [2]. It was introduced in 2007 for iPhones and in 2010 for iPads. Because the iOS phones are more expensive than Android phones, it is more prevalent in more developed countries, mainly in the USA. Its interface is based upon direct interaction with the user using touch gestures, many of them being multi-touch.

Climbing has injected new life into the island’s economy and mitigated the effects of the Greek economic crisis. A significant social shift is occurring as locals embrace climbing tourism, though there is still not a great degree of integration between climbers and locals. While climbers have relatively low environmental impact, environmental practices throughout Kalymnos need to be improved to preserve the island.

Adam Ondra y Chris Sharma, Alex Megos, Jimmy Webb y Hazel Findlay también han sido reconocidos. Desnivel.com - Jueves, 26 de Diciembre de 2013 - Actualizado a las 07:50h. La revista estadounidense Climbing ha hecho públicos los prestigiosos premios Golden Pitons (Pitones de Oro) que otorga cada año a las actividades más destacadas de la escalada mundial según diferentes puntos de vista. Kilian Jornet se ha hecho acreedor de uno de dichos galardones, en la categoría de velocidad, por sus impresionantes ascensiones exprés a montañas tan emblemáticas como el Mont Blanc o el Matterhorn, cuyo récords ostenta. La página web de la revista americana publica una introducción a la noticia acerca del premio a Kilian diciendo: "Los escaladores se han preguntado desde hace tiempo qué podría pasar si atletas de calibre olímpico de otros deportes trajeran su fuerza y resistencia al mundo vertical. Ahora, tenemos una idea bastante buena: el runner catalán Kilian Jornet Burgada está liquidando sistemáticamente los récords de velocidad en los picos más famosos del mundo". A continuación, Climbing pasa a resumir algunas de sus victorias en competiciones en carreras a pie y en esquí de montaña, para señalar que "Jornet ha escalado desde que era un niño, y en los dos últimos años, ha centrado su capacidad aeróbica casi sobrehumana en retos más técnicos".

  • Adam Ondra Climbs the World's First 9C (5.15D)
    Adam Ondra Climbs the World’s First 9c (5.15d) Prague/Norway - Sep 4, 2017 – Yesterday, Adam Ondra, one of the best rock climbers in the world, made a little piece of climbing history. He finished his project in the Hanshelleren Cave, Flatanger, Norway and established the world’s first 9c route, currently the hardest and only route of this grade in the world. After succeeding at Dawn Wall last year when he repeated the route in a very fast time, the Czech climber Adam Ondra once again set new limits of rock climbing when he successfully sent his project of 9c route in the spectacular Hanshelleren Cave in Norway. Adam has not yet named the route though he has used the working title Project Hard on many occasions in the past. He bolted the route in 2013 and focused on it last year and also this year’s entire season. He made seven trips to Norway and in total spent months there. Also he trained specifically for the project since the beginning of this year and worked closely with a physiotherapist Klaus Isele who helped him to prepare for the very specific moves. All that came together in 20 minutes of super intense climbing at the end of which stands the hardest route in the world and a new scope of what can be achieved in rock climbing. Adam Ondra about sending 9c (5.15d): „In the morning it felt like every other day on the Project. It was hot, but the air was crystal clear and dry. But I felt very little pressure and lot of psyche.

Szombathely, Hungary The influence of strength abilities on sports performance in climbing JAN DOŠLA 1 , JAN MEŠKO Faculty of Sports Studies, Masaryk University, Brno, Czech Republic ABSTRACT The article discusses the influence of strength abilities on performance in climbing. Strength abilities were measured using two motor tests, test of dynamometry and pull-up hang test. We also measured selected anthropometric parameters (height, weight, body fat percentage and somatotype components - endomorphic, mesomorphic, ectomorphic). During the research a total of 46 persons have been measured; these were divided into three groups – performance climbers, recreational climbers and non-climbers. Only men have been included in the test. Statistically significant differences were found in parameters “pull-up hang” and “body fat percentage”. No statistically significant differences between other parameters have been found. Average somatotype of the performance climbers was 2.03-4.87-2.98 which corresponds to the ectomorphic mesomorphy.

    10 MELLOBLOCCO ®10 10 years of Melloblocco ABOUT MELLOBLOCCO ® “Melloblocco ®, international boulder meeting”, is the largest outdoor bouldering meeting in the world. The idea was born in 2003 and in 2004 its first edition was organized by the Lombardy Mountain Guides, , President Ettore Togni and promoters Nicolò Berzi e Michele Comi, then by the Valmasino Municipality, Major Ezio Palleni, and recently by the Valmasino Tourist Association, President Giacomo Sertori. The meeting takes place on the many boulders scattered in Val di Mello and Val Masino (in the province of Sondrio, in Northern Italy), in a beautiful natural scene, only 140 km north of Milan. Every year new areas are added, where the participants feel the unique emotions of bouldering with the best world specialists, trying together to solve boulder problems of all difficulties. In order to motivate the strongest male and female athletes, a bunch of new problems are selected every year – based on their beauty and high or extreme difficulty, each associated to a money prize which is shared by the few who send the problem. All participants who have enrolled in the Melloblocco ® may try to send the money-winning boulders and all of them may win pieces of technical gear or clothing offered by the sponsoring companies during the event closing ceremony. During Melloblocco ® concerts, exhibitions parties and video shows are a great opportunity for climbers to share their passion and chill-out. The media, too, take their opportunity to take pictures, share views and to interview the strongest boulder specialist in the world. SOME FIGURES ON MELLOBLOCCO ® Melloblocco ® takes place every year during the first week-end of May.

    An Analysis and Critique of the Scoring Method Used for Sport Climbing at the 2020 Tokyo Olympics Michela J. Stinson∗ Department of Recreation and Leisure Studies University of Waterloo Waterloo, Ontario, N2L 3G1, Canada [email protected] Douglas R. Stinson† David R. Cheriton School of Computer Science University of Waterloo Waterloo, Ontario, N2L 3G1, Canada [email protected] August 31, 2021 Abstract Sport climbing was a new Olympic event introduced at the Tokyo 2020 Olympics. It was composed of three disciplines, and the final rankings were determined by computing the product of each climber's rankings in the three disciplines, with the lowest score winning. In this paper, we compare this product-based scoring method with the more usual sum-based method. As well, we propose and analyze a new method based on taking the sum of the square roots of each climber's rankings. 1 Introduction: Sport Climbing and the 2020 Olympics While outdoor rock climbing has a diverse and lengthy global history, competitive sport climbing1 is relatively new, with the earliest records of competitions being held on artificial walls in the 1980s [9].
