Buffers vs Codable
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Buffers
This tool helps design buffer solutions for pH control in research. It offers a calculator for accurate recipes and a reference for common buffering agents, supporting various parameters like pH, concentration, and temperature.
- 42 common buffering agents
- Accurate recipe generation
- Broad pH, concentration, temperature ranges
- Detailed buffer system information
- Shareable recipes (email, text, copy, print)
- Sophisticated calculation algorithm

Buffers is a tool for designing buffer solutions for pH control. Buffers is useful both as a handy reference of available buffering agents and as an accurate, portable buffer calculator for chemical, biochemical and biological research. With Buffers you can: - Select from 42 commonly used buffering agents - Generate accurate recipes covering broad pH, concentration and temperature ranges - Access detailed information about each available buffer system - E-mail, text, copy or print recipes To use Buffers, just choose a buffering agent and target pH along with the desired solution volume, temperature and buffer concentration. The recipe is calculated with the push of a button. Buffers uses a sophisticated algorithm that is more versatile and potentially more accurate than simple calculations based on the Henderson-Hasselbalch equation. An information page for each buffering agent lists the pKa, appropriate pH range, and temperature dependence, along with molecular weights and CAS numbers for the acid and base forms and other pertinent information. Bring your buffer calculations into the lab where you need them!
Codable
This app offers front-end web development tools optimized for mobile devices. It allows for basic debugging, rendering tests, and CSS editing of any web URL directly from your phone.
- Resizable viewport for device emulation
- View pre-rendered website source
- Inspect and edit CSS
- View and execute console commands
- Structured listing of rendered nodes

Codable is a lightweight web developer toolkit for iPhone and iPad. Use the Safari extension to inspect pages where they already run. Select elements inline, browse the DOM tree, view HTML, inspect styles and node metadata, evaluate JavaScript, capture console output, view source, inspect resources, and review network activity. On supported devices, on-device Apple Intelligence can be used to find elements and perform edits. The main app has three tabs for development and testing: - Resize: a browser surface for testing responsive layouts with custom viewport width, height, scale, presets, and drag handles. - Scratchpad: a JavaScript editor and runner with syntax coloring, code-focused keyboard shortcuts, document support, and optional Apple Intelligence assistance on supported devices. - Extension: a small info page with instructions on how to enable the Safari extension, and a way to view a local demo page with CSS, JavaScript, resources, console logs, and network requests to try out the tools within Safari.

Verdict
The clearest difference is review sentiment: Buffers at 33% against Codable's 0%. Buffers also leads on iOS requirement (14.1 vs 26.4). Codable's advantage is update cadence (monthly vs every 13 months). On price, ads, in-app purchases and monetization model there is nothing between them.
