Hermann Ebbinghaus worked this out in the 1880s. Within twenty-four hours of learning something new, the average person retains less than a third of it. Within a week, less than a quarter. And yet most frontline training programmes are still designed as though a single induction event is enough.
Frontline employees forget the majority of training within a week because training is delivered as a single event with no reinforcement. The fix is spaced repetition: short, well-timed follow-up at two days, five days and twelve days after initial learning.
MobieTrain's approach delivers three short modules over ten days for new product launches, resulting in confident, customer-ready knowledge by the time the product reaches the floor.
In an office environment, forgetting a training session is inconvenient. In a restaurant on a busy Friday night, it is the difference between a good experience and a one-star review.
A team member who cannot recall the allergen information on a new dish is not just underperforming. They are a liability.
Without reinforcement, the average person retains less than 25 per cent of training content within one week of initial learning. In the high-cognitive-load environment of a busy restaurant or retail floor, decay is faster still.
The answer is not more training. It is better-timed training. Spaced repetition, returning to material at increasing intervals before the memory fully fades, has decades of research behind it.
Microlearning platforms apply this principle at scale: a short check on Tuesday, a scenario question on Friday, a refresher the following week.
The material sticks because the brain keeps encountering it just as it would otherwise let it go.
A cosmetics brand launches a new collection. Rather than a single product knowledge session before the launch date, their MobieTrain programme delivers three short modules over ten days: the product story on day one, the key selling points on day four, a customer scenario on day eight.
By the time the collection hits the floor, the team does not just know the products. They can talk about them.
MobieTrain clients shifting from event-based to spaced microlearning report measurably higher retention scores and, more importantly, visible floor behaviour change within sixty days. Managers stop repeating the same product briefings, and team members answer customer questions confidently.

The forgetting curve, identified by psychologist Hermann Ebbinghaus, shows that humans forget approximately 50 per cent of new information within 24 hours and up to 80 per cent within a week without reinforcement. For retail and hospitality teams who need product knowledge readily available during customer interactions, this makes single-session training largely ineffective regardless of its quality.
Spaced repetition delivers short reinforcement of previously learned content at increasing intervals, typically at two, five and twelve days after initial learning. MobieTrain clients using spaced repetition report measurably higher retention and, more importantly, visible behaviour change on the floor compared to locations using the same content without the reinforcement schedule.
MobieTrain data across QSR and retail clients shows that three to four short touchpoints over a ten-day period produces reliable retention of product knowledge and operational procedures. Each touchpoint should be under five minutes. The initial module delivers the content; the follow-up checks activate recall and close the forgetting gap before it fully opens.
