Keyless Entry and Coaching App for a 24/7 Gym Franchise


Let's Connect

Problem

Key fobs, no member app

A 24/7 gym franchise with 58 clubs relied on physical fobs for after-hours entry and offered no digital member experience at all. Lost fobs generated constant front-desk work and replacement fees, off-peak access problems went unresolved until staffed hours, and the franchise had no channel for workouts, schedules or member communication beyond generic email blasts.

Solution

Keyless entry plus coaching

We built iOS and Android apps with secure smartphone entry — Bluetooth LE with a QR fallback — integrated with each club's existing door controllers and tied to membership status in real time, so lapsed accounts lock out automatically. Around access we layered guided workout plans, an exercise video library, visit streaks, and club-specific notices, giving the franchise its first direct member channel.

Measurable Impact

What changed after launch

Smartphone entry adopted by 76% of active members within 4 months of rollout

Fob replacement and access-related front-desk requests reduced by 63% across all 58 clubs

Members following an in-app workout plan visited 1.8x more often than non-users

App rated 4.6 stars on both stores with 41% of members active weekly
