<h1>Ros <span class="dash"></span>plata</h1>
<p>Rosplata is an opensource self hosted collaborative finance manager. Create budgets, share them with friends and easily split the bills.</p>
<p><strong>This is an app from the future.</strong></p>
<p>Most likely you won't be able to run it now.</p>
<p>Imagine a situation: you and your friends go to a bar (possibly abroad with no internet available). You order something, have fun. In the end you get the check and no one remembers what did they order and who spent how much. This is exactly the problem Rosplata is here to solve.</p>
