# PMI® Exam Prep 2026 vs Filter Calculator

The clearest difference is ads: PMI® Exam Prep 2026 at none against Filter Calculator's shown. Filter Calculator's advantage is update cadence (every 5 months vs every 12 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PMI® Exam Prep 2026 sells 4 in-app purchases, starting at $24.99 per month and Filter Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PMI® Exam Prep 2026 ships an update every 12 months, Filter Calculator every 5 months. The most recent releases landed on November 5, 2026 and November 6, 2026 respectively.
