What a bargain—this free app doesn’t just give you one genetic tool, it gives you an entire array! The app is divided into two sections: tools and reference. Under the “tools” heading one will find an oligo Tm calculator, tools to calculate concentration for oligo resuspension and dilution, typical reaction and cycler conditions for PCR/qPCR, and a molarity calculator, among a few other tools. The other half of the app, the “reference” section, contains some nifty resources like the chemical structures of the nucleotide bases, a table of oligo modifications, a fluorescent dye and quenching table, and a table of amino acids, as well as a couple other resources. The app is nicely organized, with the homescreen clearly displaying the two main sections of the app and all of their corresponding features.
