# ZattaMemo vs Timeline

The clearest difference is update cadence: Timeline at every 4 days against ZattaMemo's every 3 weeks. Timeline also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ZattaMemo sells 1 one-off in-app purchase and Timeline sells 2 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.

ZattaMemo ships an update every 3 weeks, Timeline every 4 days. Both last shipped on October 31, 2026.
