DCircuit Lab is a tool to simulate combinatorial and sequential digital circuits. Circuits can be simulated in two ways: 1) one single step: all the outputs values are evaluated at the same time 2) step by step: outputs and gates are evaluated one step a time If circuit contains clock inputs, its simulation is dynamic. This means that outputs change accordingly to the clocks. During this dynamic simulation, user can change inputs values to study the circuit behavior which is also provided via a timing chart. Circuits are built using basic components, gates and flip-flops: * inputs (three state: 1, 0, X - undefined) * outputs * wires * NOT, AND, NAND, OR, NOR, XOR gates with any number of inputs * Flip-flop RS, JK, T, D (Positive or Negative Edge Triggered and with Set and Reset Inputs) * Multiplexers with any number of inputs * Demultiplexers with any number of outputs * Fully configurable Clocks * Custom Components defined by their truth table * BCD to 7 Segments Display Decoder * 7 Segments Display Some video tutorials are available directly from the application to learn how to use it.

This software is provided "as is" without warranties or conditions of any kind, either expressed or implied. Features: * 2 Modes: Local (stores .tex documents on your device) and Cloud (synchronizes your projects with Verbosus) * Offline compilation (Local Mode, enable in Settings) * Use PdfLaTeX, XeLaTeX or LuaLaTeX to generate a PDF * Use BibTeX or Biber for bibliographies * Automatic Dropbox synchronization (Local Mode) * Automatic Box synchronization (Local Mode) * Git integration (Local Mode) * iCloud integration (Local Mode) * Zotero integration (Local Mode) * Mendeley integration (Local Mode) * AI assistant (available in supported regions) * Custom keyboard shortcuts * Inverse search (jump from PDF to .tex file) * Syntax highlighting * Line numbers * Autosave * Hotkeys (see below) * File upload incl. subfolders (Local Mode) * Web-Interface (Cloud Mode) * Two factor authentication (Cloud Mode, in combination with Copiosus) * No ads Additional features in VerbTeX Pro: * Code completion (commands) * Unlimited number of projects (Local Mode) * Unlimited number of documents per project (Local Mode) * Unlimited number of file uploads per project (Local Mode) * Unlimited number of projects (Cloud Mode) * Unlimited number of documents per project (Cloud Mode) * Support development of free iOS apps If you experience any performance issues when loading a project or while using the editor please try * to disable syntax highlighting and line numbers by choosing Settings -> Syntax Highlighting * to split up your project into multiple .tex files by using the include{...} command of LaTeX Import or export existing projects (Local Mode): * Git integration lets you create a new or clone an existing repository. * Automatic Dropbox or Box synchronization (Settings -> Link to Dropbox or Box). Synchronization is done once a minute. Use any .ttf/.otf font (Local Mode): If you want to use a custom font or a font that is not installed you can import it via Git integration, via Dropbox, via Box or manually via Finder. In your project you can use the font like this: \documentclass{article} \usepackage{fontspec} \setmainfont{fontname.otf} \begin{document} \section{Main Heading} Это тест \end{document} You can write chinese in PdfTeX using the CJKutf8 package as shown in the following example: \documentclass{article} \usepackage{CJKutf8} \begin{document} \begin{CJK}{UTF8}{gbsn} 这是一个测试 \end{CJK} \end{document} You can write chinese in XeTeX using the xeCJK package as shown in the following example: \documentclass{article} \usepackage{xeCJK} \begin{document} 这是一个测试 \end{document} Hotkeys in editor (can be changed in editor - settings - keyboard shortcuts): ctrl+,: Settings ctrl+s: Save ctrl+g: Generate result ctrl+f: Search ctrl+p: Preview ctrl+n: New document ctrl+d: Delete document ctrl+.: Next document

Verdict

The call

The clearest difference is review sentiment: VerbTeX Pro LaTeX Editor at 69% against DCircuit Lab's 11%. VerbTeX Pro LaTeX Editor also leads on rating (4.1 vs 3.0) and update cadence (fortnightly vs every 10 months). DCircuit Lab's advantage is price ($3.99 vs $8.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
