All participants used the same smartphone, which can also be a limiting factor, since not all phones have the same size or the same performance; therefore, the findings should be interpreted with caution. The lack of technical training on how to hold the smartphone or the inexperience of the subjects can be another limiting factor.</p></span></span><span id="sec0060" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0150">Conclusion</span><p id="par0205" class="elsevierStylePara elsevierViewall">In light of the results of this sham study on the sample studied, smartphone-mounted app-guided CPR techniques did not improve the results of compressions during resuscitation. The only variable that improved using the apps was the percentage of compressions performed at a correct rhythm. The average compression depth seems the most limiting factor to be able to make quality compressions regardless of the type of test or app used. More studies are needed to learn more on the use of mobile apps as feedback providing tools when performing CPR maneuvers.</p></span><span id="sec0065" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0155">Funding</span><p id="par0210" class="elsevierStylePara elsevierViewall">The authors declared that they did not receive any funding to conduct this study.</p></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0160">Author contribution</span><p id="par0215" class="elsevierStylePara elsevierViewall">Felipe Fernández-Méndez: study design and idea, data mining, analysis and interpretation of data; paper draft, and critical review.</p><p id="par0220" class="elsevierStylePara elsevierViewall">Roberto Barcala-Furelos: study design and idea, analysis and interpretation of data, and critical review.</p><p id="par0225" class="elsevierStylePara elsevierViewall">Martín Otero-Agra: study design and idea, data mining, analysis and interpretation of data, and critical review.</p><p id="par0230" class="elsevierStylePara elsevierViewall">María Fernández-Méndez: study design and idea, data mining, analysis and interpretation of data, and critical review.</p><p id="par0235" class="elsevierStylePara elsevierViewall">Myriam Santos-Folgar: study design and idea, data mining, analysis and interpretation of data, and critical review.</p><p id="par0240" class="elsevierStylePara elsevierViewall">Antonio Rodríguez-Núñez: study design and idea, analysis and interpretation of data, and critical review.</p><p id="par0245" class="elsevierStylePara elsevierViewall">All the authors approved the final version of this manuscript.</p></span><span id="sec0075" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0165">Conflicts of interest</span><p id="par0250" class="elsevierStylePara elsevierViewall">Dr. Roberto Barcala-Furelos has participated in the development of an educational CPR app (CPR coach®) that was not tested or mentioned in this study.
