 All the researched apps are simple to use by applying one of two techniques. Firstly, Liven and Forest guide the user throughout the app and its features using text blocks that pop up during app usage. To ensure this does not hinder the focus order and user's flow, these text blocks are shown between transitions. Secondly, apps can focus on solely one purpose, removing the need for a user journey. Minimalist Phone uses this approach. Instead of having a personalized journey or several goals that the user can achieve, it only shows the current time of day, battery percentage and focus session timer. There are no pages with separate topics, nor are there multiple topics on pages individually. There is only one page. There are presets of design, but these don't change any of the information shown. All the researched apps are simple to use by applying one of two techniques.

-Minimalist Phone's layout is simple, showing only 3 items. Liven and Forest use a completely vertical layout, setting a simple user journey where the user only goes down the screen. This simple layout and the usage of pages for separation of concern enhances the focus order because the user only has 2 ways of navigation, top to bottom and page to page. Because these apps go from top to bottom, it's also accessible for users who use screen readers, for example users with impaired vision. There is no extravagant order of information, meaning the screen reader will always read in the right order. On the topic of accessibility, deaf users have a similar experience because there are no ground-level defining functions using sounds. Liven for example only uses background music that the user can turn on by choice. Sounds do not define the experience, they only enhance it. +Minimalist Phone's layout is simple, showing only three items.

-There are 2 ways these apps ensure their light weight and fast performance without overloading the phone's processor. Firstly, Forest and Minimalist Phone have only a handful of features which are very lightweight. Minimalist Phone only shows 3 items on the screen and has the option to swap between screen savers. Forest only has features regarding focus sessions and personal profile feedback. Forest also uses animations and art that show the user their virtual forest, but it uses a simple art style and minimal animations.+There are two ways these apps ensure their light weight and fast performance without overloading the phone's processor.

 Secondly, Liven has an abundance of features and more animations than Forest. To counter graphical and computational overload, Liven generates information throughout usage of the app. Since Liven focuses on giving the user a personalized journey, most of the data gets generated at the moment, making the application very lightweight out of the box and throughout usage. Secondly, Liven has an abundance of features and more animations than Forest.

 To determine the most efficient method for indoor herb cultivation, it is necessary to first understand how growth environments affect plant development. In the context of Screen2Green, the plant system must act as a responsive bio-indicator of a user’s digital habits while remaining clean and practical for a modern desk environment. To determine the most efficient method for indoor herb cultivation, it is necessary to first understand how growth environments affect plant development.

-Traditionally, plants are grown in soil (geoponics), where organic matter acts as a reservoir for water and nutrients. However, soil is often unsuitable for desk-side IoT devices due to its bulk, the potential for mess, and its tendency to harbor pests like fungus gnats [(Barbosa)]. Crucially, soil’s high moisture retention creates a "buffer" that delays visible wilting. For Screen2Green, this is a major disadvantage because the plant needs to show relatively quick visual feedback when a user exceeds their screen time limit.+Traditionally, plants are grown in soil (geoponics), where organic matter acts as a reservoir for water and nutrients.

 An alternative is hydroponics, specifically Deep Water Culture (DWC). DWC suspends roots directly in an oxygenated, nutrient-rich water solution. While DWC is very efficient and clean, it can be technically demanding to maintain in a small, portable pot. This led to research into a "middle ground" known as semi-hydroponics. An alternative is hydroponics, specifically Deep Water Culture (DWC).

 Although LED technology is often described as the future of plant growth, there are several reasons to delay its implementation in the early stages of a project. First, the initial investment cost is relatively high, as specialized LED systems are significantly more expensive than traditional lighting or simple soil-based setups [(Olle2013)]. Second, the system introduces a level of operational complexity, since optimizing plant growth requires knowledge of Photosynthetic Photon Efficiency and Daily Light Integral [(LyineGroup2026)]. Incorrect settings can negatively affect plant health, leading to issues such as light stress or poor development. Although LED technology is often described as the future of plant growth, there are several reasons to delay its implementation in the early stages of a project.

-In addition, energy efficiency can become a concern if the system is not properly optimized. Using non-specialized or generic LED lighting may increase electricity costs without providing meaningful benefits for plant growth [(LyineGroup2026)]. Also, natural light intensity is typically much higher in southern countries compared to northern European countries [(Signore2020)]. Because Portugal has a higher DLI year-round, it is not necessary with artificial light as a sole source for photosynthesis, which is often required in windowless «plant factories» or warehouses in darker climates [(LyineGroup2026)][(Paradiso2022)]. The project will focus on apartments where it is natural to have access to natural lighting. This highlights how geographic location influences the feasibility and cost-effectiveness of LED-based systems.+In addition, energy efficiency can become a concern if the system is not properly optimized.

 Finally, successful use of LED technology often depends on integrating multiple systems, including lighting, climate control, and nutrient delivery. Starting with a simpler grain-based approach allows the project to develop gradually, requiring fewer resources while avoiding unnecessary technical challenges in the early phase [(LyineGroup2026)]. Finally, successful use of LED technology often depends on integrating multiple systems, including lighting, climate control, and nutrient delivery.
