About Heatflask
heatflask is an app that does one thing: present your recorded activities in a way that is fun and insightful. A note about this LinkedIn company: As of 5/2020, the only "employee" of heatflask is Efrem Rensi, this project's BDFL. Somehow a lot of people are claiming to be heatflask employees. They are not and I have no idea who any of them are.
