Introduction: More broadly, mobile is the main device used to connect in the internet; Last year, 70% of the Brazil population accessed the internet. In addition, there are 120M of active users/ month in the WhatsApp (instantaneous message application). In this digital connected context, there is an opportunity to zoom into their real lives by mobile approach, and at the same time mitigate the positivism Brazilian behavior when evaluating products. Objective: Explores the challenges and benefits on quantitative mobile research; evaluate the cost, timing and results impacts on this more real life scenario thought mobile recall. Methods: Quantitative monadic study with 136 consumers per protocol; home use test of combing cream to be evaluated by consumers with same profile balanced; It was compared two approaches, one with protocol 100% face to face (F2F). For the other, the approach was F2F only during recruitment/product placement, while the recall evaluation was mobile survey; for the methods comparison, it was conducted the statistical test 2-tail, t-test at 95% level of confidence. Results: Among the 200 consumers recruited, only 15% of the consumers spontaneously answered the platform on time. With follow up, it was possible to achieve more 30%. However, just after offering a tickets movie, we complete the 136 interviews. To summarize, it was necessary a 17% extra investment on the initial budget and 5 extra days. On the other hand, the formula tested on mobile recall presented inferior evaluation on Satisfaction and Application/Usage qualities. The average of characters on open ends is inferior on mobile, but the content mentioned was different from F2F which reflects the complete absence of bias in a scenario with no interviewer stimulus. Conclusion: Brazilian consumers need more stimulation to answer an autofill survey, being necessary more effort in time and budget to work this methodology. However, in the mobile scenario, they tend to be more rigorous on satisfaction and application evaluation, being a good way to soften Brazilians tendency to positivity behavior which is always reflected on product/service evaluations.
