Honesty is the hottest part of your D/s dynamic.
Whether you lead or follow, Harmony Control is your place to say the quiet things out loud. This relationship tracking app is where boundaries, limits, wants, needs, requirements, and desires belong — because the hottest part of your dynamic is when you both understand these foundations together. Once your thresholds are defined, the health chart shows you visually how your partner is doing over time.
When you're ready, invite your partner into your dynamic and create the contracts and rules you both stand behind. If a rule is broken, assign training and tasks that improve your relationship — structured accountability through a Role Playing Game (RPG) built for real growth: quests, XP, levels, and campaigns you shape over time.

Harmony Hub
Say what matters — together:
Start in two steps
Document the truth together
Boundaries, limits, wants, needs, requirements — named clearly so trust has something solid to stand on.
Turn honesty into daily practice
Tasks, rituals, accountability, rewards, and progress — so what you agreed to actually shows up in your lives.
What you unlock together
Better relationships start with honest boundaries — then structure and follow-through keep you both showing up.
For every kind of dynamic
Power exchange isn't about guessing. It's about naming, negotiating, and revisiting what you want as you grow.
Dominants & tops
Lead with clarity. Invite subs, assign training, track submissive tasks, record mistakes, apply discipline, award points, and build rituals that honor both authority and care.
Submissives & bottoms
Join free and participate fully. View assigned tasks, complete training, earn points, increase levels, voice limits, and serve from choice and clarity—not confusion about what you've agreed to.
Switches & couples
One account, multiple relationships. Dom in one dynamic, sub in another — with separate dashboards, points, levels, rules, thresholds, and history for each relationship.
Built for Doms who track submissives and subs who want structured training, discipline, points, and growth
Harmony Control helps adults make D/s relationships practical: Dom dashboards, Sub dashboards, clear expectations, documented consent, negotiated limits, tracking thresholds, submissive training tasks, discipline records, rewards, points, XP, levels, and routines that keep care visible after the intensity fades.
Dom/sub and master/slave relationship tracker
Record dominant and submissive roles, master/slave agreements, service expectations, rituals, rules, rewards, consequences, and relationship history so both partners understand the dynamic they are choosing.
BDSM agreements, contracts, and rules
Create consent-first BDSM contracts for adults: rules, boundaries, hard limits, soft limits, safe words, aftercare needs, privacy expectations, relationship check-ins, and ongoing accountability.
Tasking, service, and training structure
Support top/bottom dynamics, dominant/submissive roles, switches, and couples with a private command center for service tasks, rituals, training plans, reminders, and negotiated power exchange.
Consent, safety, thresholds, and aftercare
Track trust, safety, respect, tasks, training thresholds, journals, notes, mistakes, discipline, rewards, and aftercare so power exchange stays grounded in communication and care.
Harmony Control is for consenting adults only. It supports healthy relationship dynamics and does not promote coercion, abuse, or non-consensual control.
Track submissive training, mistakes, discipline, rewards, points, and relationship levels
Harmony Control is designed for consenting adult D/s dynamics that need more than a chat thread. It gives the Dom and Sub a private system for accountability, training, progress, and relationship growth.
Submissive training tracker
Assign service tasks, rituals, training plans, daily challenges, reminders, requirements, and focus time so submissive training becomes visible and repeatable.
Mistake and discipline log
Record submissive mistakes, notes, broken rules, discipline actions, punishments, consequences, privilege removals, lockups, presentation sessions, and follow-up tasks.
Points, XP, and levels
Both Dom and Sub collect points, XP, streaks, achievements, and rewards. Use gamified relationship levels to make effort, service, consistency, and growth easier to see.
Level up relationships
Track trust, safety, respect, health scores, custom thermometers, training thresholds, Last Resort thresholds, and relationship trends so partners can level up together.
Harmony Hub — where truth lives
A shared space to log what matters, so trust can grow deeper:
- Boundaries — what must not be crossed
- Limits — hard and soft edges, honestly stated
- Wants & needs — what you crave and require to feel cared for
- Requirements — non-negotiables you both acknowledge
- Desires & fantasies — named with care, held in private
- Household finances — budgets, financial limits, assets, liabilities, goals, allowances, and forecasting
- Shared calendars — appointments, tasks, rituals, family events, D/s sessions, date nights, and reminders
Both partners contribute. Respect can be tracked and rewarded. Budgets, Sub allowances, family calendars, and household goals stay visible. The app holds what you agree to—it doesn't replace conversation.
"Boundaries aren't buzzkills. They're the foundation. When you document limits and desires in one place, intensity becomes safer — and a lot more intoxicating."
Run the relationship, the household, and the dynamic from one private command center
Harmony Control is more than a BDSM relationship app. It helps couples, families, and D/s partners coordinate the practical side of life: shared calendars, family schedules, household budgets, financial limits, Sub allowances, assets, liabilities, financial goals, and forecasting.
Household finance tracking
Track monthly income, budgets, actual spending, financial limits, assets, liabilities, debt payments, and net worth so money agreements are visible and easier to revisit.
Sub allowances and financial control
Doms can assign Sub allowances, define cadence and conditions, and include allowances in the couple's monthly cash-flow forecast for clearer financial accountability.
Financial goals and forecasting
Plan emergency funds, trips, debt payoff, savings targets, and relationship goals with simple six-month forecasts that connect budgets, payments, allowances, and contributions.
Shared family calendar
Create appointments, tasks, rituals, reminders, date nights, family events, check-ins, deadlines, and D/s sessions in one shared calendar built for couples and structured households.
How it works
Three steps: register free, connect your partner, then document truth and train with structure.
Register free
Choose Dom, Sub, or Switch. No credit card required. Create your private D/s relationship tracker and start with consent-first setup.
Connect your dynamic
Invite your partner or accept their invitation. Doms can invite subs, subs can accept dynamic invitations, and each relationship has its own history.
Document & train together
Fill Harmony Hub with boundaries and desires, sign contracts, assign tasks, track progress, and watch trust, safety, and respect grow over time.
Strengthen your bond with submissive training, mistake tracking, discipline, rewards, thresholds, and check-ins
Better D/s relationships are built through repeatable care, visible accountability, and consistent follow-through. Harmony Control helps partners turn dominance and submission agreements into submissive training, service tasks, discipline records, rewards, points, levels, and measurable trust.
Training and tasking
Create submissive training, slave training, service tasks, rituals, reminders, requirements, daily challenges, rewards, and accountability loops that support the relationship you both negotiated.
Mistakes and discipline
Record mistakes, talkback, discipline, punishments, privilege removal, lockup sessions, presentation, rewards, consequences, and notes so accountability has context.
Threshold tracking
Use trust, safety, respect, relationship thresholds, custom thermometers, and Last Resort thresholds to spot patterns early and keep the dynamic emotionally sustainable.
Leveling up relationships
Make relationships better with points, XP, streaks, achievements, rewards, Dom levels, Sub levels, leaderboards, shared accountability, trust, service, and care.
Finance control and household planning
Bring budgets, financial limits, Sub allowances, family finance tracking, assets, liabilities, and financial goals into the same private system as your relationship agreements.
Calendars for couples and families
Use a shared calendar for appointments, family tasks, rituals, D/s sessions, reminders, date nights, check-ins, and deadlines so daily structure supports the relationship.
