Why this program matters

  • Without mastery of Expo and React Native, 70% of internally developed mobile apps suffer from degraded performance, generating critical bugs and excessive load times.

  • This results in an average loss of 42% of users in under 3 seconds, equivalent to 150 000 € in potential revenue evaporated per project.

  • Companies see their deployment timelines double, with maintenance costs exploding by 30% annually, directly threatening profitability and competitive position.

  • Every month without solid skills exposes your team to recurring project failures and stalls developer promotions.

Our method

How Learni guarantees the quality of your High-Performance Mobile Apps training

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
