Simple, Useful Android Apps by DIYTech Labs

Featured Apps

Two apps carry most of what we do. Draw Signature is the studio's longest-running app: a simple way to create a signature once and reuse it on any document. Dociq is our newest: a document scanner designed so your pages never leave your phone. Around them sits a small shelf of everyday utilities — a calculator, a status saver and more — each built to do one job without getting in your way.

Draw Signature

Create your handwritten signature by drawing on screen or typing in stylish fonts, then save it as a transparent PNG for documents and forms.

From Tutorials to Apps

DIYTech Labs did not start as an app studio. It started in 2017 as DIY Tech Pro, a small tutorials project where founder Rahib Ali published the electronics experiments he was working on: making a laptop keyboard glow with a one-dollar USB light, wiring a headphone splitter by hand, testing the 18650 battery cells rescued from dead laptop packs. The write-ups were practical and step-by-step, and people read them — a couple are still linked from other websites today.

The readers changed the direction. Under the tutorials, people kept asking for the same thing in app form: the signature tool from a video, a calculator that did not fight them. So the projects became apps. The signature app grew into Draw Signature, and the habit of explaining things clearly became the studio's support style and the tutorials still maintained on this site.

Today the studio works the other way round: apps first, tutorials when they help. Dociq, our document scanner, follows the same rule the tutorials did — solve one real problem, respect the person using it, and keep everything on their own device. If you arrived here from an old tutorial, welcome back; the apps page is where that project lives now.

What is next is more of the same, deliberately. Dociq is preparing for its Google Play launch, Draw Signature continues to be maintained and improved, and the older tutorials on this site are being kept accurate rather than abandoned. We would rather have a short list of apps that people keep installed than a long list they try once — so new releases arrive when they are ready to be useful, not on a schedule.
