License and Disclaimer.


This Software Product, in all its thematic variants

(including Startup Product Manager, Photovoltaic System, All-in-One PV Anlagenbewertung, SocialMedia driven App developer, Internet of Things developer, Business Process Manager, Predicted Desire, Perfect Desire, and the 21st century worldwide Growth of Forest Simulation)

as well as The Reverse Experience (T.R.X.) – as available on

– http://www.dynamic-applications.com and/or http://www.dynamic-applications.org –

have been created, designed and programmed, and are owned by
Martin Bernhardt, Founder of Dynamic Applications.

This Software Product is declared and provided to you as Freeware (thematic variants and T.R.X., as available via above websites, including dynamic-apps.eu) or Shareware (Perfect Desire, Windows 10 Store Apps) under the following terms and conditions.

Terms and Conditions.


You may copy and run the product on one of your own personal computers,
You may use the product for your own purpose, on your own risk,

provided that the software product as such remains unchanged, and its Info dialogue, the copyright information and this license are included.

This is not an open source software, as we are afraid that lots of cracked versions, and all kinds of minor-quality derivates, adware and spyware, could be resulting from this.

You may not modify the program’s executable or dlls, neither modify or re-package the setup installer, without written permission from the author.

Dynamic Applications are much about providing free or micro-payment, interactive, and powerful Business Model Calculators for every single person in the world. Being the Founder, i’m guaranteeing their functionality with my own name.

We’re not saying that everything is perfect, but they are as good as we are able to do them, and you are encouraged to send in any bug reports or desirements you may have. We’ll look at them and fix what’s possible as soon as possible. Impossible things tend to take a little longer at the moment. It’s a work in progress.

The Technical concept is published in The Desire Language Specification on our website. Feel free to develop your very own approach of a System Dynamics – based projection software. There’s a lot of details to solve, we did that, and that’s probably why some people are crowdfunding us with 99 cent for multiple person years of work.

They wanted to give something back after using it for a year, or even before.

About 1 per mille of downloaders have already done so, and we are grateful for that. We think you’ll feel much better if you go the same way. So be rewarded.

Take pride in your work, not in the money in your pocket. Same chances for everyone. Be part of an international network of people competing for the best App in the world.


Usage Conditions.


Due to the nature of System Dynamics being a Top-Down Approach for analysis and understanding of complex system behaviour, all parameters and formulas we use for prototype models perform as sample configuration, only. We say everything is implemented as specified. Any requirement of adjustments to default formula or input parameters of our software will require an individual contract. Should you have expert knowledge and claim that any specific formula or parameter are irritating or defect, should be adjusted to be more precise, or be corrected, this is welcome.

We are grateful for any comment, and do our work as good as possible. As part of our principles though, please know that we don‘t consider Input and Target Value, or Formula System feedback or desirements as a description of formal defect of our software. Instead, there is a user competition for new and existing ideas, features, and platform improvements. Formally spoken, all of our products are simply game models, in being our very own reference implementations. We do not claim they fulfil any specific reason or meaning.

We’ll accept as desciption of defect any relevant issues or defects in our differential equation solver engine, the core of our solution. It allows us to publish more models, frequently. As you can imagine, any additional model brings a little effort in maintaining with it, so that’s why there’s the Dynamic Idea competition. Focus on the best ideas that you, the SocialMedia crowd following, prefer us to do. We’re going to fix any defects in the differential equation solver engine asap, as well as fix reproducible crashes or defects in other parts of our software, should there ever be any.

Don’t fuzz with us about the 2-digit rounding precision though, we just do it this way. It’s not relevant to look at simulations on future expectations in microscopic detail.

As with every winner in this world, there have to be a few losers as well.

It is forbidden to use our software for any military purpose, as well as in nuclear power plants, in companies operating these, and in other circumstances that directly endanger the life of people. You agree to use anything we publish or send to you on your own risk, except where otherwise stated in written offering. We do our work as good as possible, but there’s always the chance of a mistake.

Freeware Conditions.


As long as the price is free, you may deploy any of our Software Products, excluding Perfect Desire, on any media or channel of your choice, considered the conditions of this license are fulfilled. Our Software Products and their Setup or Appx package must be unchanged for this.

Specifically, no adware, no spyware, and no data gathering software may be packaged with our software which remains on the customer’s computer after installation.

In offering Business Model Calculations, we guarantee the privacy of your very own idea for this world. May you offer our products in a Zip, or other common archive format? – yes.

Shareware Conditions.


From March 2017, through the Dynamic Applications Web Store, we offer a market place for selling your customized dynamic application. You set the price, we offer your product to the world.

we take 25%. You get 75%.

Please apply by mail if you’re interested, so we have a rough idea of participants and can schedule 2nd-level support. At the moment, we recommend you start with a freeware license to gain an interested user base in the beginning. As soon as you desire, we simply add a PayPal button in front of your download which points to your personal bank account at the moment. So you have to share the revenue with PayPal, who are gonna take about 25% from you. We win from your promotion of the Dynamic Applications Web Store. We could also say you can keep 100% of any net profit, as long as you care for your own bank account fees resulting from sales, and sell your product through the Dynamic Applications Web Store, as an introductory condition throughout 2017.

We think is a really fair share, considering we are programming Perfect Desire, the core, and got all the work here. So you can take all our work for free, define a small adaption, there you go.

In the long run, we’re targeting a true App Store concept.

So from 10 Euro sales price, your share will be 7.50 Euro, our share will be 2.50 Euro.

From your 75%, we recommend you pay your tax, for some people who call themselves gouvernment. Everything else is going to be your net profit. You help us expanding, we give 3/4 back to you. For 25%, we’ll support you for free, as long as personally and technically possible. Also, you enable us to drive the software forward.

In case you require specific customizations, our 2017 customer waiting list is your place to go.

Reseller Conditions.


You are allowed to sell any of our products, even on higher prices than we charge ourselves, throughout 2017, as stated below. Basically everyone can join and start reselling our Software Products, as long as you agree to share 25% of your total revenue with us.

Idea: it’s your business. We respect that.
We take 25%. You get 75%. We support you for free.

So in case you’re reselling our products through your own Website or Store, you’re obligated to send 25% of your total revenue (resulting from end customer sales pricing) to us. Apart from that, you‘re free to publish, and it’s very easy, so just go ahead. If you’re goint to drive lots of business to your website, we’re gonna find you. You are allowed to earn an amount of 100 Euro this way before sharing anything. As soon as revenue reaches 100 Euro, you agree to send the first 25 Euro to us.

The minimum price for reselling our Software is 0.95 Euro per single product license.
If you want to go below that, you have to publish our public beta for free.

The maximum allowed price for reselling our Software is 20 Euro for any product, bundle, or media where any or multiple of our products are part of.

Dynamic Applications is all about enabling people, so if you want, take our products and start your own business, today. We’re most probably going to raise standard prices in 2017. This is a full-time effort, and i can not feed my family from 1 per mille voluntarily crowdfunding users. It was getting desparate.

For this reason, we’ve removed the reseller license for Perfect Desire, our all inclusive solution. From 25 April 2017, Perfect Desire is the one product exclusive to Dynamic Applications. You are not allowed to publish Perfect Desire as Freeware, Shareware, DonationWare, or under any other reseller condition.

Formally spoken, you are not allowed to publish Perfect Desire, itself.

You may only re-sell your own, acquired and customized version.

Expanding, worldwide.


At Dynamic Applications, we work to empower people. We are Sharing Economy. Follow us to gain.

You are welcome to set Website links to any of our Websites without any further request as long as you agree to do it on your own behalf, and on your on risk. In being a freeware author, we simply don’t have the possiblity to back you up with a lawyer. You can always ask us for help in case of problems, we just can’t guarantee to solve anything for you.

Feel free to see http://www.dynamic-applications.com (or below) for contact information and send in a request for your specific purpose – it may be granted with no further issues, so it’s always worth to give it a try. Please don’t try to earn money from us by activating a bunch of lawyers, we don’t have much. We are Sharing 100% of a lifetime‘s work and knowledge, that’s all.

The author is always thankful for a little comment that you have reviewed our software, or linked back to us. In case you mention us on Twitter, expect retweets to about 25.000+ Followers free of charge – as a little thank you for your efforts – as long as we see you provide something useful for the SocialMedia crowd in your Tweet (e.g. nice pictures, blog entries, Entrepreneur Tipps and Tricks, quotations about life and reason).

We think that this way, from 2018, we’ll have found the perfect team of 1-st level supporters and resellers, in worldwide collaboration. That’s why we’re doing it this way. The other reason is that we’re always interested in solving complex problems, so we do it first and then we incorporate our best thoughts down as part of our free business planners, ToolTips, or Website documentation.

Privacy Protection.


Perfect Desire, all its derivates, and The Reverse Experience are being designed as traditional, standalone Windows 7 / 8 / 10 clients on purpose. No Spyware, No Adware, No paid 3rd party banners, No data gathering, No Server behind. Test this anytime by switching off your WiFi or LAN connections to the International Network („Internet“). Dynamic Applications are going to work.

The only things that refuse to work are online documentation, user competitions on Twitter, and update weblink, naturally. We simply startup those links on your Operating System’s default Web Browser, that’s all. So don’t blame us, you’ve plugged it out, yourself.

It’s your business. We respect that. And we want a professional, reliable solution for the professional business user, so we make all our solutions offline-capable by concept. Your Internet Connection is gone? – no problem at all. Your company keeps productive. So if you’re much about that BigData history research concept, or similar kind of giveaway nonsense, or if you require to send in as many data as possible, please find some other company to help you on.

At Dynamic Applications, we support transparent machine calculations for the public, and privacy for the people. This way, we prove that all the machines and products we calculate got a realistic business case, to everyone. In case you’re using our Windows 10 Store Apps, you’ll get automatic, unlimited upgrades for all of our products, including Perfect Desire. As we operate no Webserver of our own, we don’t know much about how they do it. We think for every app that’s in the store and every user, they just track the latest downloaded version, and show a small (1) to you for every update we publish. You hit one button if you want to get it, and there you go. We recommend you ask Microsoft in case you have a problem with how they do it. We intend to have the better concept.

We keep our software small for the perfect user experience, even with a bad internet connection in a poor country. We think poor people are important as well.
