Is there a platform or a software that allows people to share/compete their PBs?

Hello, makers! I work in marketing for a Japanese sports nutrition supplement company. Currently I'm looking for a platform/software that allows you to share and compete against your own personal best records, with "Like" function. I know there are many similar apps, but my knowledge is limited and I haven't found a platform, software, or anything like a mini program/mini app that meets expectations.
