Tasks, rules, rewards, punishments, check-ins and private journals for Dominant/submissive relationships, in one encrypted couples app.

A D/s relationship app gives Dominants and submissives a single, private place to run their dynamic, rules, tasks, proofs, rewards and consequences, instead of juggling chat threads and notes. UNION makes authority and accountability feel effortless.
Codify your dynamic with a living rulebook. Set standing protocols, position rules and rituals that both partners can reference anytime.

Assign tasks with deadlines and require photo or note proof of completion. Accountability without nagging.

Reinforce obedience with rewards and follow through on consequences, all tracked and tied to real behavior.

Regular mood, energy and consent check-ins keep the dynamic healthy and make sure structure never outruns wellbeing.

Private and shared journals let submissives report and Dominants reflect, building a written record of your growth together.

Tasks, proofs, check-ins and encrypted chat keep authority and connection intact even when you're apart.

Whether you lead, follow or move between both, UNION adapts to your dynamic.
Assign tasks and rules, review proofs, grant rewards and manage consequences from a single dashboard, so you can lead intentionally, not administratively.
Always know what's expected, submit proof, request permissions and journal your progress in a space that makes serving clear and rewarding.
Flip roles per scene or period while keeping one shared history, so your dynamic stays fluid without losing structure.
