This paper studies both $$\Lambda $$ CDM and CDM models under the über gravity theory, named ü $$\Lambda $$ CDM and üCDM respectively. We report bounds over their parameter phase-space using several cosmological data, in particular, the recent Pantheon+ sample. Based on the joint analysis, the best fit value of the über characteristic parameter is $$z_\oplus = 0.046^{+0.047}_{-0.032}$$ and $$z_\oplus = 1.382^{+0.020}_{-0.021}$$ at 68% confidence level for ü $$\Lambda $$ CDM and üCDM respectively. Although über gravity can successfully mimics the cosmological constant, we find that the $$\mathbb {H}0(z)$$ diagnostic suggests the $$H_0$$ tension is not alleviated. Finally, both models are statistically compared with $$\Lambda $$ CDM through the Akaike and Bayesian information criteria. Both über gravity models and $$\Lambda $$ CDM are equally preferred for most of the single samples, in particular, ü $$\Lambda $$ CDM is not rejected by the CMB data. However, there is strong evidence against them for the joint analysis.
