# PMDD Tracker vs AlignerPro

The clearest difference is update cadence: AlignerPro at every 6 days against PMDD Tracker's every 3 months. AlignerPro also leads on rating (5.0 vs 4.8). PMDD Tracker's advantage is ratings volume (187 vs 1) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PMDD Tracker sells 2 in-app purchases, starting at $9.99 per month and AlignerPro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AlignerPro holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: PMDD Tracker has 187 ratings behind it against 1, so its average is the more settled of the two.

PMDD Tracker ships an update every 3 months, AlignerPro every 6 days. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
