Spaced repetition,
applied to actual work.
The technique is not new and not controversial. What is rare is a platform that schedules every concept for every learner rather than shipping the same refresher to everyone.
What is the spaced repetition method?
Spaced repetition means reviewing information at increasing intervals, timed so that each review lands just before you would have forgotten it. Recalling something at that moment strengthens the memory far more than reading it again straight away.
The effect has been studied since Ebbinghaus mapped the forgetting curve in the 1880s, and it is one of the most consistently replicated findings in learning research. It is why medical students and language learners have used flashcards for a century.
Repetition, not rote
The word repetition does the method a disservice. Asking someone an identical question over and over teaches them the shape of that question — which option sat third, which phrasing looked right — and remarkably little about the thing underneath it.
So a concept comes back as a variation instead. The same returns policy might arrive as a multiple choice, then as a missing word, then as a customer standing there with no receipt and an item bought eleven months ago. Different angles on one idea, which is what builds understanding rather than a memorised answer.
Does it actually work at work?
The technique is well evidenced; the difficulty has always been fitting it into a working day. That is a delivery problem rather than a science problem, and it is the one we set out to solve in 2014.
Two to three minutes a day on a phone is short enough to survive a shop floor, a galley or a plant. Vertex cut training time by 87% while retention rose 60% — the format is not a compromise on rigour, it is what makes the rigour possible.
Why the scheduling has to be personal
A fixed refresher calendar treats a concept everyone finds easy and a concept everyone struggles with identically. That wastes time on the first and never fixes the second.
Here every individual concept has its own decay curve for every individual learner. Someone solid on returns policy but shaky on warranty terms gets more warranty questions and fewer returns questions, without anyone having to configure that.
Spaced repetition in the Wranx platform
The science is the easy part. These are the decisions that make it work on a shift.
Quick and engaging
Two to three minutes a day, on a phone, in a gap that already exists. Nobody is taken off the floor to learn.
Long-term retention
Spaced repetition brings each concept back as it is about to fade, so knowledge is still there months later rather than days.
Confidence, measured
Certainty-based marking separates someone who knows it from someone who guessed right — the difference that matters on the job.
Competitive elements
Streaks, progress and standings keep people coming back, and can be switched off entirely where a league table would do harm.
Any device, any time
Runs on whatever people already carry, around shifts and time zones, with progress synced across all of it.
Proof, not completions
Reporting on what each person actually knows, concept by concept, rather than who clicked through the module.
It is the engine, not a feature
The same scheduling drives the daily drills, the mastery ladder and Voice Coach. When a learner rehearses out loud, it practises what they keep getting wrong in writing — because both run on one model of what that person knows.
Wranx success stories
See how managers, like you, are using Wranx to make training land.
With traditional e-learning you can get saturated with information and knowledge – and that becomes useless. Wranx does the complete opposite and allows learners to digest information easily and at their own pace.
This platform has had a direct impact on our customers, as a higher level of training has ensured they have an enjoyable experience in store. The uplift in sales is clear, as customers said they were influenced by our store colleague’s advanced product knowledge!
I have heard nothing but positive feedback from our employees about using Wranx. It’s a much more doable format for them and almost makes a game out of learning. It’s more bite-sized and doable on a repeat basis.

Frequently asked questions
Two to three minutes. That is a deliberate constraint rather than a marketing number — every design decision defends it, because training that needs an hour is training that gets deferred.
No. The concept returns on schedule, but usually as a different question — a different format, a different angle, a different situation. Recognising a question you have seen before is not the same as knowing the material, and only one of those survives contact with a customer.
A refresher schedule is fixed and applies to everyone equally. Spaced repetition is calculated per learner, per concept, and changes every time someone answers.
It comes back sooner and more often until it is secure, then gradually spaces out again. Nothing is scored negatively — mastery rises through demonstrated understanding and fades through time.
