B737 Performance Handbook

The B737 Performance Handbook is currently trending mostly sideways to slightly downward across the eight markets where it charts in the Education category's Top Grossing ranking on the App Store. Its strongest market today is Tajikistan at #10, followed closely by Morocco at #12, while the rest of the footprint sits further down the chart, from Rwanda at #27 down to Niger at #58. Movement is largely muted: Rwanda is the only country showing a small uptick (+1), and several markets — Benin, Mauritania, Cape Verde, and Niger — held position unchanged, whereas Tajikistan, Morocco, and Algeria each slipped four to six spots. With an all-time peak of #6 reached on 2026-08-04 and a 30-day average around #17, the app appears to be coasting well off its high but holding onto a stable, niche footprint rather than actively climbing or collapsing.
