OCT Shipping Rates Calculator ranks #1 for rate calculation with 6.7% share — the leader position in a fragmented field where many apps are within striking distance, -4.3pp ahead of CBB Shipping Rates Calculator (11.0%). Zapiet ‑ Rates by Zip Code sits at #3 with 29.5% share, rounding out the top tier. The top 3 apps together control 47.2% of rate calculation installs — a clear leadership tier with a meaningful long tail behind them. Dostavi.bg ‑ BG Shipping is the standout mover this month, climbing 2 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.
Rate Calculation is a fragmented market — the top 3 apps together hold only 47.2% of installs, leaving OCT Shipping Rates Calculator's 6.7% lead modest in absolute terms and Zapiet ‑ Rates by Zip Code at 29.5% still capturing meaningful share. With this many viable apps, pricing model and integration depth differentiate rate calculation options more than rank does.
OCT Shipping Rates Calculator climbed from #2 (May 2026) to #1 (Sep 2026) — a 1-position gain among rate calculation apps over the charted window. Among the top 5 plotted rate calculation apps, 1 improved and 1 declined — rankings reshuffled without a single category-wide direction. OCT Shipping Rates Calculator's share expanded +4.1pp from 2.5% (May 2026) to 6.7% (Sep 2026) — a sustained widening of the gap against other rate calculation apps over this window.
Stable rankings across the top 5 plotted rate calculation apps mean merchants have largely settled on their preferences — challengers below the top 5 face an uphill path to break in.

CBB Shipping Rates Calculator is closest to the milestone — its current count puts it roughly 21% of the way to 1,000.
ShipX ‑ Shipping Rates & Rules is the only app in this set to have crossed 1,000 reviews so far — a useful signal for merchants that one app has already proved sustained adoption while the others remain in the "promising but unproven" tier of the rate calculation category.
