# Plan vs Weeknummer

The clearest difference is in-app purchases: Plan at none against Weeknummer's 1. Plan also leads on iOS requirement (13.0 vs 15.6). Weeknummer's advantage is update cadence (every 4 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. Weeknummer sells 1 one-off in-app purchase. Plan asks for nothing beyond the download.

Plan ships an update every 2 months, Weeknummer every 4 weeks. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
