About RJ Dev Studio

Independent, product-first, and focused.

RJ Dev Studio is an independent app studio based in India. We build focused mobile products that support meaningful routines without unnecessary noise.

Starting with Jaap Counter

Jaap Counter is our first public app: an Android digital mala for Tap, Auto, and Volume counting, Mantra Focus, personal goals, meditation, and long-term practice journeys.

We care about clear product decisions, respectful devotional details, and plain explanations of how features and data work. The app has no ads, supports free local backup, and offers optional private Google Drive snapshots for people who want them.
