HazeApps is a set of lightweight educational and everyday utility apps developed by Hashan Rajapaksha. Its website lists apps such as BooleanTT, SolveXY, and StApp, with 500K+ total downloads and a 4.2+ user rating. Its core focus is not generative AI, but rather a collection of algorithmic tools for Boolean algebra, digital logic, equation solving, and student management.
BooleanTT covers step-by-step Boolean expression simplification, the Quine-McCluskey method, 2/3/4-variable Karnaugh maps, truth tables, SOP/POS, number-system calculations, logic operations, logic circuit simulation, and generating circuits from expressions. SolveXY supports step-by-step solving and graphing for linear and quadratic equations. StApp is aimed at students’ daily routines, offering tracking for attendance, assignments, timetables, GPA, and more. The available materials do not disclose any AI models, LLMs, or training data, so it should not be treated as an AI generation tool.
Pricing information is incomplete. The page states that the apps include Google AdMob ads and use Google Play and Pay Here for payments. The privacy policy also mentions subscription data, but does not list plan prices, free allowances, or trial periods. On privacy, login is handled through Firebase Authentication, and basic profile data such as name, email address, and public profile photo URL may be collected. Advertising, analytics, crash reporting, and payments are handled through Google/Facebook SDKs, AdMob, Crashlytics, Google Play, Pay Here, and similar services. HazeApps says it does not store payment details, but it may view account profiles and subscription data through Firebase management software for customer support.
The main advantage is its strong focus on educational scenarios, especially for learning Boolean algebra and digital logic. Step-by-step explanations, interactive tutorials, a smart keyboard, history records, and localization help lower the learning barrier. The drawbacks are that AI capabilities are absent or undisclosed, pricing transparency is limited, API/integration capabilities are not explained, support appears to be limited to email and chat entry points, and the terms state that the apps are provided “as is” with no guarantee that they are error-free.
It is suitable for students taking electronics, computer science, or discrete mathematics courses, as well as users who need to solve equations quickly or manage study-related tasks. Access from China cannot be determined from the available materials. Because it depends on services such as Google Play, Firebase, AdMob, and Google login, users in mainland China may face network or payment instability. Alternatives to consider include Wolfram Alpha, Symbolab, GeoGebra, Microsoft Math Solver, or a dedicated Karnaugh Map Solver.
