Soil organic carbon is very important because it constitutes the largest reservoir of carbon in terrestrial ecosystems. Maintaining and increasing soil carbon is an option to reduce the amounts of CO2 in the atmosphere, and thereby, to reduce or mitigate climate change. The SOC is now a topic of great interest hence it is recommended to know the amount of SOC along the profile to select and evaluate those areas that should be preserved. The aims of developing App SOC plus were to eliminate the calculate errors of SOC and to make a tool to estimate SOC in field. The common units of measurement of soil properties were employed: bulk density in mg mL&#8722;1, horizon thickness in centimetres, stoniness and organic carbon in percentage. The App SOC plus was developed in the Android platform. App SOC plus involves a three-step process: introduction of soil properties, calculation of SOC to horizon and soil profile, and conversion of units using the international and English systems. As a result, there will no longer be confusions with conversion units using App SOC plus; with App SOC plus the soil organic carbon can now be calculated or/and estimated because it provides instructions (aids) to estimate the soil properties necessary to calculate the SOC in the soil profile. You can save time in the calculation of SOC. App SOC plus is a tool for diagnosis in the field.]]></p></abstract>
