Background/ Objectives: Consistency is recognition of the fact that it is easier to do things in a familiar context. Consistency makes software applications more comfortable to use the objective of the paper is to evaluate software consistency as an indicator of usability for social software's. Methods/Statistical analysis: A sample of 345 respondents was selected. The data was collected through the use of questionnaires and interview targeting mobile social users in 11 constituencies of former Rift valley province of Kenya. The researcher purposively sampled WhatsApp, Facebook and Twitter as software’s used in this study. Descriptive statistics were used to analyze the data. Findings: This finding indicated that that 30.1% of the respondents agreed that the interface is consistent in the whole application in Facebook, followed by 15.4% in WhatsApp while 4.3% agreed in Twitter. Regarding whether icons and images are consistent in the whole application, it was reported by 36.8% of the respondents to be consistent in WhatsApp while Facebook users confirmed 16.5% while Twitter users were 6.7%. The findings further indicate that the social software becomes more consistent its usability increases, the consistency of shortcut keys with the operations, consistency of color, type and fonts displays influence usability of the social software. The paper has provided insights that consistency is vital, software designers should consider it in the software development process. Improvements: there is need to conduct further studies on other social software to confirm if these results are in line with all social software.
