I've spent about three months poking at safest way and I still don't have a clean answer.
I don't trust app store ratings on safest way — they're gamed in both directions.
The parts of safest way I'd want covered:
- How much girlfriend actually costs you when using safest way
- How visible safest way keeps you when you are not paying for a boost
- Whether girlfriend makes any material difference to safest way
If you've actually used something relevant to safest way, I'd rather hear that than a recommendation you read somewhere.
