About Techy.

What Techy is

Techy is an independent project by Adrián García Caballero. It brings together practical guides, free tools and small apps for organizing work: shift schedules, working time, handovers, appointments and the everyday processes of small teams and businesses.

Every guide solves one concrete task and includes a worked example you can check. The tools run in your browser and need no account.

How it is funded

Techy is funded by its apps and, on guide pages, by advertising that is labelled as such. Ads never appear on product, support or privacy pages, and no advertiser decides what we publish. Our editorial policy, privacy policy and cookie policy are currently available in Spanish: editorial policy, privacy, cookies.
