TagMo needs your help to remain active

TagMo is struggling to fund development. Since being abandoned in 2020, TagMo is privately funded and published by a single developer.
TagMo does not contain ads and does not track usage.
Since restoring TagMo, support has been added for more phones, games, hardware, and various other features. Updates are released regularly.
A build machine has burned out from the workload.
TagMo is the only Android app of its kind. While multiple iOS clones exist, these apps take inspiration, if not some of their code, from TagMo.
TagMo is more than an Android app, it's a resource.
Similar app charge around $5+ per user. If 75% of current TagMo users donate $1, TagMo would remain funded for the foreseeable future.
TagMo could cease to be maintained without funding.
