Great App - Except for intrusive adds

This is a great application. However, I find it almost unworkable because Google throws so many adds at you they either, distract your work, take over the screen, shut down the app dumping your work, or try and sell you an add blocker.

There needs to be an add free version of this for a reasonable cost.

Nice but should be more immersive.

What i mean by immersive i mean like when you drop the bomb theres a model of that bomb. Then the app would be better for me.

best app ever

i now get to defend my country’s friend and bomb north korea
thx

Interesting, but some errors

Overall, this is a very interesting app. It is unique and really allows users to see the devastation that nuclear weapons could produce.
However, I still noticed some errors, specifically with the β€œestimated causalities” section. When using a nuke on Hawaii, I consistently got around 3.9 million causalities as an estimate. The current population of Hawaii is only about 1.5 million. I’m not sure if the app is trying to take into account tourists, but I don’t believe there is almost 4 million people on there main island of Hawaii at one time. That was just something I noticed though.
Overall, unique and interesting app.

Error issue

When i first got this, i liked it. Now it seems to have a major issue. I think this app was created in russia. When calculating the number of casualties for Moscow, all I get is an Data unknown error message, yet when i do the same on Washington dc i get the results on casualties. A bit one sided.

FAQ

What does BlastSim do?

BlastSim is a free application that calculates the area affected by a nuclear explosion. It uses researched formulae to predict the range of thermal radiation, the radius of radioactive fallout, and the potential number of casualties. This can be useful for understanding the impact of nuclear events and for evacuation planning.

What are the key features of BlastSim?

Key features include the ability to calculate the affected area, predict thermal radiation range and fallout radius, and estimate casualties. It also includes a list of historical nuclear weapons and allows users to input custom weapon yields in kilotons.

Is BlastSim free to use?

Yes, BlastSim is a free application. There are no costs associated with downloading or using its features. The app does not have in-app purchases or advertisements.

What kind of nuclear weapons can I simulate?

The app includes a list of popular nuclear weapons from history, such as Little Boy, Fat Man, and Tsar Bomba. Additionally, you have the option to input a custom yield for any weapon in kilotons to simulate its effects.

How can BlastSim be used for evacuation planning?

By simulating the potential radius of thermal radiation and radioactive fallout, users can gain an understanding of the immediate and lingering dangers from a nuclear explosion. This information can inform decisions about safe zones and evacuation routes, contributing to more effective disaster preparedness.
