# TimeTrex vs OneSource Mobile App

The clearest difference is update cadence: TimeTrex at every 3 weeks against OneSource Mobile App's every 4 months. TimeTrex also leads on rating (3.9 vs 3.6) and ratings volume (106 vs 13). OneSource Mobile App's advantage is monetization model (free vs freemium). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
