PROFESSIONAL REPORTS & ARCHIVE
Export supported calculations and records as polished PDF, Excel, or CSV files. Customize PDF reports with your company logo, brand color, address, accreditation line, operator and instrument details, signature lines, page numbering, and footer text. Save results in the in-app Archive for later review and reporting.

FREE TO USE, WITH OPTIONAL PRO
Core calculators and everyday utilities remain free to use. A 7-day trial automatically unlocks all PRO calculators, advanced validation and instrument tools, full Archive access, and exports from the first launch — no credit card required. After the trial, continue using the free tools or subscribe to retain full PRO access.

BUILT FOR REAL LAB WORK
• No account or sign-up required
• Calculation data and saved records remain on your device
• Clear in-app explanations for formulas, inputs, assumptions, and technical terms
• Light and dark themes
• Available in English, German, Russian, Chinese, Japanese, French, and Spanish

Whether you are preparing a standard, checking a chromatographic method, reviewing QC data, planning a new instrument installation, or creating a validation report, LabTools keeps essential laboratory work organized and close at hand.

What’s new

• Lab Leveler: level an instrument or bench using the phone's own sensors, with spoken guidance so you can watch the feet instead of the screen
• Instrument troubleshooting: more detail in all seven guides, and a clearer line between what an operator may do and what belongs to qualified service
• Lists that can be scrolled now show an arrow, so options further down are no longer missed
• Minor fixes
