rollApp lets you run desktop apps, work with files, get things done — right from the browser on any device.

Online tools for learning chemistry

We have diverse collection of the applications available on our online platform, including any apps for educations. Today we want to tell you about applications that can help you in studying chemistry.

Simple and effective gElemental is a periodic table viewer that provides detailed information on the chemical elements. It offers a broad, up-to-date data set, thematic coloring and a sortable list view.

Another app is Cain: it allows to perform simulations of chemical reactions and can spawn multiple simulation processes. The reactions may have mass-action kinetic laws or arbitrary propensity functions. Once you have run a simulation to generate trajectories (possible realizations of the system) you can visualize the results by plotting the species populations or reactions counts.

Kalzium is an all-around chemistry application. Kalzium includes a Periodic Table of Elements, chemical reference, chemical equation solver, and 3D molecule viewer. With the help of rollApp you can launch it from any device online!

Design Electronics Online

There are many great apps available online on rollApp and today we would like to tell you about gEDA. gEDA project is developing a toolkit of Electronic Design Automation tools for electrical circuit design, schematic capture, simulation, prototyping, and production. The tools involved in the suite enable professional-quality design of schemes of low- to mid-level complexity. Using the gEDA tools, you can create PCB of up to 8 layers with an unlimited number of components and nets.

Another great tool for the creation of professional schematics is KiCad. It comes with a rich set of libraries with 3D models and allows to design printed circuit board up to 32 copper layers.

gEDA and KiCad on rollApp make it possible to work on your schemes on any device – even tablet or smartphone. It works great on Chromebooks, which makes it a great tool for students, who study electronics.

Explore the sky online with Stellarium on rollApp

For thousands of years people have been looking up at the stars at night. The invention of the telescope was a major step in the study of our universe. Today, technology has leaped forward and we can look at the stars, learn the constellations and galaxies with a computer. Stellarium on rollApp allows to explore the skies on any device – tablet, Chromebook, or smartphone online.

Stellarium is a planetarium for your device. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.

This application is a great lense to learn about the Universe with default catalogue of over 600,000 stars, asterisms and illustrations of the constellations, realistic Milky Way, very realistic atmosphere, sunrise and sunset, planets and their satellites and much more!

Krita – great painting application – needs our help

Krita is a powerful digital painting program used by artists all over the world. And latest and greatest version of Krita (2.9.4) is now available on rollApp.

Launch Krita online

Krita has a lot of interesting functions like multiple brushing and blending modes, advanced symmetry and masking tools, and allows to create true digital masterpieces. Check out examples of great work done in Krita in the artwork gallery.

Here is what Dmytro Bidnyak, Senior Designer at rollApp, says about Krita: “I’m really impressed with Krita 2.9. This is very interesting solution for digital painting and sketching. It has stunning performance and a magnificent collection of brushes. I think, Krita’s digital pencil is one of the best I ever saw.” Take a look at Dmytro’s work on his site.

Krita developers have set an ambitious goal to make their software faster than Photoshop when working with big canvases with big brushes. Krita Foundation currently runs Kickstarter campaign to support further development. Let’s help make great software even better!

Stay tuned for further updates!
