Frequently Asked Questions

Everything you need to know before getting started

Is there a free version?

Lab Tools Pro offers a 7-day free trial with full access to every feature โ€” all 100+ calculators, 150+ protocols, lab notebook, reference databases, and Apple Watch app. No credit card required to start. After the trial, choose the plan that works for you: monthly ($2.99), yearly ($19.99), or lifetime ($39.99).

What platforms does it run on?

Lab Tools Pro runs natively on iPhone, iPad, Mac, and Apple Watch. One subscription covers all your devices. Everything syncs automatically via iCloud โ€” start a calculation on your phone, pick it up on your Mac.

Does it work offline?

Yes, 100%. All calculators, protocols, and reference databases work completely offline. Perfect for lab benches without WiFi, field work, or cleanroom environments. The only features that need internet are PubMed search and iCloud sync.

Can I cancel anytime?

Absolutely. You can cancel your subscription at any time through your Apple ID settings. If you cancel during the free trial, you won't be charged at all. No questions asked, no hoops to jump through.

Are the formulas accurate?

Every calculation engine uses peer-reviewed formulas with high-precision decimal arithmetic (not floating-point). The app was built by a research scientist (Dr. Shankar Dutt, ANU) and every formula has been verified against published scientific literature.

How does it compare to free online calculators?

Online calculators require internet, cover only one calculation at a time, don't save your history, and have no quality guarantee. Lab Tools Pro gives you 100+ verified calculators offline, saves every result, syncs across devices, and includes protocols, reference data, and a lab notebook โ€” all in one app.
