What is the 28-day cliff?

Boutique fitness studios lose roughly 50% of new members within 28 days. The pattern is consistent: a new member books 4–6 classes in their first 2 weeks, then attendance drops, then they cancel. Drift Radar surfaces the silent third week — when bookings drop but they haven't formally churned — and fires personalized re-engagement outreach. Catching them at day 18 saves a member that day 35 won't.

Does Retention IQ work with Mindbody and Mariana Tek?

Yes. Retention IQ sits alongside Mindbody, Mariana Tek, Glofox, Pike13, WellnessLiving, ClubReady, ABC Fitness, Zen Planner, and most fitness studio platforms. It reads attendance and membership data; nothing changes about how members book classes.

How does Retention IQ handle class-package buyers?

Class-package buyers (10-class packs, 20-class packs) drift differently than auto-pay members. The engine flags package buyers with 4+ classes remaining who haven't booked in 14+ days. Outreach references the specific package balance — 'you have 6 classes left in your pack' converts way better than 'we miss you.'

What about empty classes in off-peak hours?

Saturday 9am classes are full. Tuesday 11am is often three people. The engine identifies under-attended class slots and fires outreach to dormant members whose historical class-time preference aligns with the open slot. Off-peak utilization improves without crowding peak classes.

🧘 Built for fitness studios

Your new members aren't gone.
They're just 21 days into the 28-day cliff.

Member retention software built for fitness studios.

Fitness studio retention software tracks each member's attendance rhythm, catches the 28-day new-member cliff before it cancels, surfaces class-package buyers with classes left who haven't booked, and drafts targeted re-engagement outreach in your studio's voice. Retention IQ does it with three things nobody else has: Book Value (your studio priced as an asset), Drift Radar (per-member drift detection), and Voice Training. Works with Mindbody, Mariana Tek, Glofox, Pike13, WellnessLiving.

A new member who books 4 classes in week one, 2 in week two, then 0 in week three is on the 28-day cliff. By day 35 they're emailing you to cancel. By day 18, a personal re-engagement note saves them. The cliff is a window, not a wall — but only if you watch it.

We tell you which member is on the cliff this week, draft the message, and let you send it from your own number. That's it.

The attendance clock

Every member has a rhythm. When it breaks, we know.

Drift Radar learns each member's personal attendance norm — 4x/week, twice weekly, Saturdays-only — and surfaces the silent week when the pattern breaks.

Class-pack buyer

14-day silence

4+ classes left and not booking. "You have 6 classes left" beats "we miss you."

Pre-lapse cadence for memberships. Reactivation sequence for the ones who slipped.

Two leaks every studio has

One problem you can see. One you can't.

Leak 01 · The member side

Half your new members churn in 28 days.

They were on fire week one — 4 classes, glowing 5-star review. Week two: 2 classes. Week three: silence. By day 35 they're an email asking to cancel. The intervention window is day 14 to day 21 — early enough to feel like care, late enough to be a real check-in. We watch for it.

new-member churn by day 28

Leak 02 · The package side

A third of class packs go unfinished.

A 20-class pack with 8 classes remaining is $200+ of paid, deferred revenue that's earning you nothing but goodwill loss. Package buyers go quiet because nobody reminded them they had classes banked. We surface them by name, with their actual balance, ready to book.

"Hi David — wanted to check in. You have 8 classes remaining from the pack you bought in March, and they're still yours whenever life lines up again. No rush, just didn't want them to slip your mind. Mike has openings most Tuesday and Thursday evenings."

Every message is drafted from the member's actual history, in the instructor's voice. You approve, tweak, and send from your own system. We never message on your behalf — your members see you, not a third party.

Trained on what you actually run

Speaks your class format, not "business in general."

It knows yoga members drift slower than HIIT members. It knows CrossFit drop-off looks different than barre. It knows class-pack buyers and auto-pay members need totally different outreach. You don't have to teach it.

Membership-type tracking

Auto-pay members

Monthly unlimited, annual, family plans. Drift detection on weekly attendance norm — fires before the cancel email.
Class packs

10-pack, 20-pack, unlimited drop-ins. Balance-aware outreach: 'you have 6 classes left' is the highest-converting message in fitness.
New-member onboarding

First 28 days separately instrumented. Day 7, day 14, day 21 touchpoints catch the cliff before it fires.
Drop-ins & intro offers

Free-week trial drop-offs, $99-intro-pack buyers. Conversion-to-membership sequence built for the high-intent first 60 days.
Multi-format & multi-location

Yoga + barre + strength members tracked across format. Multi-location members tracked across studios.

Operator intelligence

Per-instructor scorecards

Lead instructors, sub-instructors, owner-operators — each with role-fair benchmarks for attendance, member retention, and rebook.
Off-peak class fills

Tuesday 11am chronically half-empty? The engine identifies dormant members whose class-time preference aligns and fires outreach.
Cross-format suggestions

Strength members ready for a mobility class. Cardio members ready for recovery. The engine knows which format pairings convert.
Membership tier modeling

Test what restructuring your unlimited or adding a hybrid tier would do to MRR before you announce.
Discount guardrails

If a member is on their attendance norm, no offer — they're coming. If they've been silent 30 days from a 4x/week rhythm, a small reactivation may help. You set the rules.

Works with your studio platform
