I recently did the two-month trial of Strava's premium features and ended up paying to keep them. Not because I want/need the detailed analysis of my running but because of the safety features.
Is it really worth it? Probably not since I can manually start it via the app but for safety, but I like the automation. My watch is also set to auto-detect running. So if I don't hit the start button and just start moving at a running speed for over three minutes it'll also alert my emergency contact with the GPS link and all. So for my peace of mind, I paid for the year with my Google Play credits that I earned from the Google Opinion Rewards app so it didn't actually cost me anything for the year. Maybe by next year they'll lower the cost or make Beacon's automatic option an à la carte cheaper feature.
