I'm embarrassed to say that I never used any formal a/b testing tools. I just fully converted to subscriptions, and ran it for a few weeks, and compared it to the previous few weeks (which were one time purchase.)
You don't need A/B testing tools. Most people don't like being tested on. Trust your gut, listen to your users, and just beware of vocal minorities. It seems like you're doing well already.
That’s a shame because it seems like you did the smart and effective solution without wasting your time. A/B testing isn’t needed if the signal is clear enough (¡parachute testing!), and it is hard to get enough samples for a weak signal. Good on you.
