Screenshots and reviews are very, very limited channels of information.
Reviews can be gamed, even when they're not, the ratings provided are typically highly inflated or simply binary (people give very high, or very low ratings, few in the middle). While descriptions can be useful, in practice most are not ("works great", "does everything I wanted" -- doesn't tell me "... for what" or "... and that was ..."). Negative reviews are often more useful (they're generally specific as to faults), but even then, as apps change over time, it's not clear what reviews relate to the current state of your app (Starbucks generally doesn't radically change its coffee composition from week to week).
Screenshots show a static view of an app but not its flow, responsiveness, accuracy, stability, privacy policy, and a whole slew of other issues.
The best way for me to judge software is to use it. Often for a prolonged period of time.
