# TNDM > TNDM (pronounced "tandem") is the commitment system for recurring routines. We pair you with the right person on schedule, level, location, and real life — then keep the routine going when life pushes back. TNDM is built for high-commitment routines: running, walking, tennis, pickleball, cycling, and lifting. It's not a fitness app, not a dating app, and not another social feed. ## Pages - [Home](/): Find your fit, keep showing up.
