Notebook calculator for iPhone, iPad and Mac: Soulver 4 is refined

A new version of the versatile text-based calculator app Soulver has been released, offering enhanced features tailored for users working with numbers on Apple devices. The update, titled Soulver 4, expands the tool’s capabilities beyond basic calculations, integrating advanced functions for finance, travel planning, engineering, and more. Developed by independent software studio Acqualia Software, the app continues its mission of combining note-taking with mathematical problem-solving, providing an alternative to spreadsheet applications like Numbers or Excel. The latest iteration introduces several key improvements aimed at streamlining workflows for professionals and casual users alike. One major addition is the inclusion of a dedicated sheet for defining variables, allowing users to set up reusable parameters such as currency rates, time zones, or unit conversions once and apply them across multiple calculations. This feature simplifies repetitive tasks and ensures consistency in complex projects. Additionally, the app now supports time-point calculations, enabling users to track durations and schedule events with greater precision. This functionality is particularly useful for travel planners or project managers who need to manage timelines effectively. Soulver 4 also enhances its hashtag system, which allows users to tag specific lines of text for later reference or statistical analysis. This makes it easier to organize data and extract insights without switching between apps. For those working in specialized fields, the update includes support for technical units such as volts, amps, and ohms, along with tools for calculating wood processing metrics, vehicle performance indicators, and music-related values like MIDI notes and frequencies. These additions reflect the developers' commitment to catering to niche user groups while maintaining accessibility for general audiences. In terms of usability, Acqualia has made adjustments to improve the interface, ensuring that totals displayed on the right side of the screen no longer overlap with values in the sidebar. This change reduces visual clutter and improves readability, especially when handling large datasets. The company has also addressed several long-standing bugs, demonstrating a focus on refining the user experience rather than merely adding new features. Pricing for Soulver 4 remains consistent with previous versions, offering options for both one-time purchases and subscription-based access through Setapp. The app can be bought outright for €69 for iOS, iPadOS, or macOS users, while upgrades cost €29. Users who prefer a rental model can opt for the Setapp service, though there are no mandatory subscription fees. Importantly, the developers have chosen not to integrate AI-driven features, instead relying on their proprietary engine called SoulverCore to handle computations. This decision underscores the company's emphasis on simplicity and control over automation. As the release gains traction among Apple device users, the app is likely to attract attention from individuals in fields requiring frequent numerical input, such as finance, engineering, and creative industries. With its continued evolution, Soulver aims to solidify its position as a go-to tool for those seeking a more intuitive and flexible approach to managing data on mobile and desktop platforms.
