HOW ACCESS WORKS
Full access needs a subscription or a one-time purchase. Yearly starts with a 7-day free trial for eligible new subscribers; Monthly has no trial. Lifetime is a single purchase that never renews. Every plan unlocks the whole app. Try the Molarity calculator free first; the app shows prices before you buy.

CALCULATORS
Solutions and dilutions, pH and buffers, nucleic acids (primer Tm, copy number, qPCR ΔΔCt), proteins, cell biology, nanopore analysis, centrifugation, enzymes, statistics, spectroscopy and chromatography, research pharmacology, environmental chemistry, microbiology, materials science, thermodynamics, bioinformatics and food science. "Use in…" sends a result to the next calculator.

MASTER MIX, PLATES AND CURVES
Build PCR, qPCR, RT, digest, ligation and assembly mixes with overage and water to volume, from presets or your own templates. Lay out 6- to 384-well plates with standards, samples, doses and controls in replicate, send the reaction count to the mix, and export a PDF plate map or CSV. Fit linear, quadratic or 4PL standard curves for BCA, Bradford, ELISA and qPCR, reporting results only inside the calibrated range.

PROTOCOLS
Scale reagents to your sample count, follow steps in full-screen Bench Mode with timers that keep running when the screen locks, and log each run to the notebook. Write your own, or edit a copy of a built-in one.

NOTEBOOK AND INVENTORY
Record experiments with templates, tags, linked calculations and protocols, photos and scans, then export PDF or CSV. Track reagents with lots, locations and expiry dates, scan barcodes and labels, and print labels whose QR code opens the item.

RECIPES AND REAGENTS
Scale 50+ media, buffers and stocks to any volume or strength, make them from stock solutions, swap hydrate and salt forms, and log each batch.

TIMERS, WATCH AND WIDGETS
Run several timers at once, or chains that run steps in order and repeat in cycles. On iPhone, timers show on the Lock Screen and in the Dynamic Island. On Apple Watch: synced timers, quick molarity, dilution and unit math, a counter, a stopwatch, six protocol checklists and your inventory list. Add widgets for timers, recent calculations, experiments and inventory alerts. Ask Siri to open any calculator or start a timer.

YOUR DATA
Your records stay on your device. Only calculation history syncs, between your iPhone and iPad through your private iCloud account. Settings > Export Data saves history, favorites, settings, custom protocols, inventory, mix templates, recipes, reagents and plate layouts to a file you can import; notebook entries export as PDF or CSV. No account, no ads, no tracking.

RESEARCH USE ONLY
For research and education. Not a medical device; not for diagnosis, treatment or clinical decisions. Verify critical results independently.

SUBSCRIPTION DETAILS
Lab Tools Pro Monthly and Yearly renew automatically unless cancelled at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase, or when the Yearly free trial ends. Manage or cancel in your App Store account settings.
