Our free plan is free forever. We have no 30 day trial. If you'd like to "test" OptimalSort - sign up on the free plan, then upgrade when you are ready.

When you upgrade, we add any remaining time you have on a plan to your new plan. So if you upgrade after your 10th day from a 30 day to a 90 day, you will be subscribed for 100 days.

We recognise that for you, it's not easy getting budget for this type of thing.

So, email us and we will give you a hefty discount.

Note:
You must be able to prove you're from a legitimate university or not-for-profit, and that you're using it for the purpose of that organisation. Please reward our generosity by being honest.
