Mooflet is the independent companion app for VanMoof e-bike riders. Connect over Bluetooth, control your bike, track every ride, and get the switches and readouts you actually want. Mooflet works with every recent VanMoof: • Electrified S2 / X2 (2018–2019) • S3 / X3 (2020–2021) • S5 / A5 (2022–2023) • S6 (2024+) FULL BIKE CONTROL • Unlock and lock from your phone • Adjust motor power level from your device • Change lights, bell, and speed region on the fly • Live battery, odometer, and signal strength readouts • Adaptive Speed Mode (ASM) that adjusts your top speed to your riding pace CUSTOM SOUNDS & CALIBRATION (S3) • Upload your own audio as your bell, or use the built-in Air Horn • Wheel calibration for riders who swap the Smart Cartridge between frames RIDE TRACKING BUILT FOR CYCLISTS • GPS speed, distance, and route recorded automatically • Full-screen speedometer with battery and lifetime distance • Save every ride as a cycling workout in Apple Health, with route • On-screen confirmation when your ride is saved FREE, WITH AN OPTIONAL AD-FREE UPGRADE Mooflet is free, supported by occasional ads. If you owned a paid version before it became free, you keep the ad-free experience forever — no action needed. You can upgrade to ad-free anytime from Settings with a one-time purchase. FEWER ADS, YOUR CHOICE You can turn off the pop-up ads by opting in to share anonymous ride data (road quality, battery, and odometer). It's collected on your device, entirely optional, and you can stop anytime. In a hurry instead? Watch a single ad in Settings and the pop-ups pause for 24 hours. SUPPORT MOOFLET Mooflet is built by one rider. If it makes your rides better, you can leave a small tip in Settings. Tips never unlock features. They simply keep the project rolling. PRIVACY Mooflet stores your bike credentials on your device, never on our servers. Ride routes are written to Apple Health with your permission. Anonymous ride data for the optional "fewer ads" program is collected only with your consent and kept on your device. See the full Privacy Policy for details.

Verdict
The clearest difference is in-app purchases: RSA Lab at none against Mooflet's 1. RSA Lab also leads on ads (none vs shown). Mooflet's advantage is update cadence (every 4 weeks vs every 42 months). On price, device support and iOS requirement there is nothing between them.
