LabCompanion puts the whole bench in your pocket. The calculators, protocol timers, and reference cards every wet-lab scientist reaches for, in one fast, offline-first app. No subscription. Unlock Premium once.

Lab calculators that just work
Dilution (C₁V₁=C₂V₂), molarity, serial dilution, primer Tm, centrifuge RCF↔RPM, cell counting, buffer pH, % solution, resuspension, and DNA/RNA concentration — all unit-aware, with copy-ready results and European-comma support.

Protocol timers that don't need babysitting
Build multi-step protocols and run them with automatic step progression. Background notifications fire at every step — even while your phone is locked — and a Live Activity keeps the countdown on your Lock Screen and Dynamic Island, so you don't have to keep the screen awake.

Reference cards, offline
Codon and amino-acid tables, restriction enzymes, antibiotic working concentrations, DNA/protein ladders, buffer recipes, unit conversions, and lab safety symbols — always available, no signal needed.

Lab Notebook (Premium)
Capture observations and photos at the bench, organise with tags, search instantly, and export any note to PDF. Everything syncs privately across your devices with iCloud.

Free to use. Premium is a one-time unlock — no card needed to try it, and there's nothing to cancel.
