# Frequency Analyzer vs mod.Reminder

Frequency Analyzer and mod.Reminder are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Frequency Analyzer sells 11 in-app purchases, starting at $2.99 per 7 days and mod.Reminder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Frequency Analyzer ships an update every 8 days, mod.Reminder every 10 days. The most recent releases landed on October 12, 2026 and September 22, 2026 respectively.
