LocalToolbox : Offline Tools

193 offline tools: ruler, level, timers, converters, text and dev utilities, image tools, finance, ledger, engineering and office helpers, plus six privacy tools.

Local Toolbox is a privacy-first, fully offline utility app that now includes 193 practical tools for daily life, work, local records, study, image tasks, and professional use.

It brings measurement tools, timers, date and unit converters, text utilities, developer tools, finance and record tools, field and workplace helpers, image tools, and fun utilities into one app. Many small tools that would normally require separate downloads are already here and ready to use.

Everything runs locally on your device. No login, no internet required, no cloud sync, no content upload, and no ads, subscriptions, or in-app purchases getting in the way. It is built for people who want practical tools without privacy trade-offs.

V2.2 adds six privacy tools: a local authenticator (TOTP), text redaction, photo metadata viewing and one-tap stripping, screenshot redaction, link tracking cleanup, and a privacy checkup checklist. All of them run on device, so authenticator secrets, the text you redact, and the photos you process never leave it.
