Before you download
All eight Apple apps are free to download. Sidewall Maven and Bucket Maven include read-only examples; Fabric Belt Splice and Motor Maven let you explore included examples. Paid access unlocks the editing, calculations or exports described on each product page. Splice Maven QA provides all QC features for free, with an optional purchase to remove dashboard advertising.
Check the platform label on each app card, then review Apple’s compatibility section for the required OS version. Belt Installation Maven supports iPhone, iPad, Mac and Apple Vision Pro; Fabric Belt Splice supports iPhone, iPad and Mac; Motor Maven supports Mac and Apple Vision Pro. Other apps have their own supported platforms.
Fabric Belt Splice plans step and finger splice geometry and prepares drawings and build instructions. Splice Maven QA records the inspections, process readings, photos and signatures from the job. They serve different stages of the work.

Courses developed and taught by Dr. Andrew I. Hustrulid — onsite for companies, and through Colorado School of Mines, SME and EduMine.
Colorado School of Mines ProEd · In person
October 14–16, 2026 · Golden, Colorado
Three days with Dr. Andrew I. Hustrulid covering conveyor engineering, component selection, installation, maintenance and troubleshooting—from the field and the factory, as well as the calculations.
Every attendee receives CEMA's Belt Conveyors for Bulk Materials, 7th Edition.
SME MINEXCHANGE 2027 · In person · Save the date
February 27–28, 2027 · Denver, Colorado
Two days of practical insight into designing, maintaining and troubleshooting reliable bulk material handling systems in the real world, at the Colorado Convention Center as part of the 2027 SME Annual Conference & Expo.
Featured instructors include Carrie Hartford (Jenike & Johanson), Todd Hollingsworth (NEPEAN Conveyors) and Andrew Hustrulid (Maven Software).
Presented by the Bulk Material Handling Committee of SME.
The first course devoted to the conveyor pulley: shaft, shell, end disk and locking assembly from first principles to the shop floor, taught to your engineering team on your own pulleys. For pulley manufacturers, companies entering pulley manufacturing, and the end users who depend on them.
An introduction to conveyor belt systems in mining, aggregate, and bulk-material handling: how conveyors are constructed and designed, how each component works, and the safety practices that keep them running reliably.
Builds on Conveyor Systems 101, covering inspection routines, belt tracking and troubleshooting, preventive and predictive maintenance, and the real cost of carryback, spillage, and downtime.
Independent engineering support for conveyor systems, from concept design through failure investigation and expert testimony.
Independent engineering review
Already have X-ray images or scan video of your belt or splice? Get a professional, independent review with Andrew Hustrulid, PhD, PE.
Understand cord layout, splice geometry and calculated load sharing. See the example written report and narrated video in English, Spanish and Brazilian Portuguese.
Tracking Maven · Belt tracking review
Send us a video of 2½ complete belt revolutions at the tail or take-up. Tracking Maven will generate a tracking profile of your belt.
Watch the splice section pass in our example video, with the belt and rollers identified and the tracking profile following the belt’s movement.
