Frequently Asked Questions
Everything you need to know about Obstetric Tools, how it works, and how we protect your information.
Is the application free?
Yes, downloading and using the basic features of Obstetric Tools are completely free. Additionally, we offer premium features for professionals who require more advanced calculations and tools.
How does the Premium version work?
You can choose between a monthly subscription, an annual subscription, or a one-time payment for lifetime access. Subscriptions include a free, no-obligation trial period so you can test all the features; you can cancel anytime.
What if I had already purchased the app previously?
You don't have to pay again! If you bought the paid version in the app store in the past, the app will automatically recognize you as a 'Founding Member' and grant you lifetime Premium access for free.
Do I need internet to use the app?
No. We know that cellular coverage in delivery rooms and hospitals can be poor. All Obstetric Tools calculators and features work 100% offline so you always have your tools at hand.
What happens to the privacy of my patients' data?
Privacy is absolute. Our app works exclusively as a blind calculator. We do not collect, do not save, and do not transmit any medical or identifying data from your patients. Everything is processed ephemerally on your own phone.
