I built a free Android app to calculate whether it's cheaper to charge or refuel your PHEV — looking for beta testers.

Hi everyone, I'm an amateur developer and PHEV owner. I got fed up trying to work out in my head whether it's cheaper to charge at home, charge at work, or just use petrol — so I built an app to do it properly. My app calculates the real daily and annual cost of four strategies: Optimal charging (splits outbound/return across cheapest rates) Start location charging only Destination charging only Petrol only It supports 30+ PHEV models, UK/EU/US units, and gives a clear recommendation based on your electricity rates and commute distance. It's completely free, no ads, no account needed (only Google). I need 12 people to test it for 14 days so Google will let me publish it publicly. If you'd like to help, comment below or DM me and I'll send you the beta link. Cheers 🙏
