NEB Tools vs Promega Protocols
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NEB Tools
This app provides essential tools for molecular biology experiments, including enzyme selection, buffer condition calculation, and PCR primer temperature determination. It also offers DNA/RNA mass conversion, ligation calculations, and dilution computations. Access technical support directly through the app.
- Enzyme Finder for restriction enzymes
- Double Digest Finder for buffer conditions
- Tm Calculator for PCR primer annealing temperature
- NEBioCalculator for DNA/RNA mass, ligation, dilution
- Quick access to technical support

NEBtools brings New England Biolabs’ most popular web tools to your iPhone and iPad, allowing you to plan your experiments from anywhere. Use Enzyme Finder to select a restriction enzyme by category, recognition sequence, overhang or name to find information on that enzyme. Determine buffer and reaction conditions for experiments requiring two restriction enzymes using the Double Digest Finder. When using either of these tools, look for Time-Saver and HF enzymes for the ultimate in convenience. Use Tm Calculator to calculate optimum annealing temperature for PCR primers when using NEB polymerases and buffers. Use NEBioCalculator to convert DNA or RNA mass to moles, calculate insert ligation amounts, convert OD to concentration, and calculate basic dilution and molarity. NEB Tools for iOS also enables quick and easy access to NEB Technical Support by phone, email, or web when you need it.
Promega Protocols

The Promega Protocols app allows you to select and run protocols for a range of Promega kits. You can add notes and use timers during the protocol run, edit Promega Protocols to create your own custom protocols, or enter your own protocols and save them locally on your iOS device. Features include: • Save records of protocol runs • Add notes to protocol steps • Create customized versions of Promega protocols • Enter your own protocols • Export (e-mail) a pdf file summarizing the details of completed protocols

Verdict
The clearest difference is iOS requirement: Promega Protocols at 9.0 against NEB Tools's 15.6. On price, update cadence, ads and in-app purchases there is nothing between them.
