This app acts as a viewer for sequence, structure, and neutralization data for broadly neutralizing anti-HIV antibodies and the HIV-1 strains they recognize. It is meant to be a quick tool for scientists involved in HIV vaccine research. Many broadly neutralizing anti-HIV antibodies have been isolated in the last decade. These antibodies recognize the Env protein on the surface of HIV. Some of these antibodies are being studied as potential therapeutics. More generally, knowledge about how these antibodies develop and recognize HIV is guiding efforts to develop an effective vaccine against HIV. This app can provide a quick reference to relevant data and perhaps serve as a tool to uncover correlations that can be further investigated.

Verdict
The clearest difference is update cadence: LEO UCR at every 6 months against HIV Antibody Database's every 33 months. HIV Antibody Database's advantage is iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
