Research-only laboratory toolkit
Lab Tools Pro
A precise bench companion for routine research math, protocol timing, reference lookup, and notebook capture across iPhone, iPad, Mac, and Apple Watch.
- 139 research calculators built on high-precision arithmetic
- 140+ guided protocols with step timers and bench presets
- Lab notebook, references, and PubMed search in one place
Built by Dr. Shankar Dutt of DuttLabs, a working scientist who wanted bench math that is fast, exact, and stays on the device.
Lab Tools Pro is for research and education only. It is not for diagnosis, treatment, patient care, patient dosing, or regulated scientific decision making. Verify critical calculations independently before use.

A short, silent tour of calculators, protocols, references, and timers moving together the way they do during routine lab work.
Tool coverage
Purpose-built for research and teaching labs
The public tool catalog is framed for research and education. Clinical decision support, diagnosis, treatment, and patient dosing workflows are intentionally excluded.
Molecular biology
DNA and RNA quantification, copy number, oligo resuspension, PCR master mix, and ligation planning.
Protein workflows
A280, Bradford and BCA planning, standard curves, molecular weight, SDS-PAGE, pI, and antibody dilution.
Analytical chemistry
Beer-Lambert, HPLC resolution, GC indexing, mass spectrometry, absorbance conversion, and column volume.
Nanopore analysis
Pore resistance, blockade analysis, translocation time, capture rate, field strength, and noise estimates.
Statistics and curves
Descriptive statistics, sample size, LOD and LOQ, curve fitting, and standard curve workflows.
Everywhere in the lab
The same toolkit adapts to the device in use

Questions
Honest answers before you commit
A few common questions about access, devices, privacy, and what Lab Tools Pro is and is not for.
Is there a free version?
There is no permanent free tier. Lab Tools Pro is a paid app with a hard paywall, but you can try a free, fully functional calculator preview inside the app before you pay. The monthly and yearly subscriptions also each include a 7-day free trial, so you can use the full app at no cost for the first week and cancel any time before it ends.
Which devices does it run on?
Lab Tools Pro runs on iPhone, iPad, Mac, and Apple Watch. A single purchase covers all of them when you are signed in with the same Apple ID.
Does my data sync, and is it private?
The app is local-first. Calculations, notebook entries, custom protocols, and timers are processed on your device. Optional iCloud sync, which you can turn on or off, keeps supported data current across your devices through your private Apple account. There are no advertising or tracking SDKs.
How do refunds and cancellations work?
Purchases and subscriptions are handled by Apple. You can cancel a subscription any time from your Apple ID settings, and you can request a refund through Apple at reportaproblem.apple.com. Lifetime access can be restored on any device with the same Apple ID.
Can I use it offline?
Yes. Calculators, bundled references, protocols, notebook entries, and timers work without a connection. PubMed search, optional ELN export, and iCloud sync need internet access.
Can I use it for clinical or diagnostic work?
No. Lab Tools Pro is for research and education only. It is not for diagnosis, treatment, patient care, patient dosing, or regulated decision making. Always verify critical calculations independently.
Privacy
Local-first by default
Calculator values, notebook entries, custom protocols, timers, and inventory data are processed on device. Optional services activate only when you use them.
- No advertising SDKs. The app does not include third-party tracking or ad identifiers.
- Optional iCloud sync. Sync uses your Apple account when iCloud is available and enabled.
- User-initiated PubMed search. Queries go to NCBI only when you perform a search.
- User-controlled ELN export. Exports go only to the provider you configure.
