The E6B Descent Planner provides a fully functional circular slide rule for use in real time descent planning. Using one finger, and with a single turn of the rotating inner disk, pilots can easily perform calculations to determine top of descent distance, angle of descent, vertical descent rate required, glide ratio, maximum glide distance based on altitude, plus many other calculations that are not commonly associated with a mechanical E6B.

Verdict

The call

The clearest difference is rating: iFly EFB at 4.7 against E6B Descent Planner's 3.5. iFly EFB also leads on update cadence (every 3 weeks vs every 9 months) and ratings volume (353 vs 14). E6B Descent Planner's advantage is in-app purchases (none vs 8) and iOS requirement (8.0 vs 13.0). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iFly EFB holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: iFly EFB has 353 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 90% of iFly EFB's written reviews are positive against 92% of E6B Descent Planner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iFly EFB ships an update every 3 weeks, E6B Descent Planner every 9 months. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
