I coded the first version of Keep My Friends after getting one too many "I haven't heard from you in months" messages from my friends. Everyone is busy (including me), but I found it very easy with the app reminding me to keep in touch with important people in my life and maintaining Streaks of unbroken contact in the app.
I ain't confortable with paying for something I haven't been able to use before. Personally, I'd rather use a free trial than a refund guarantee. But it's my opinion though :)
