# OLEDX vs KeepLit

The clearest difference is update cadence: KeepLit at every 9 days against OLEDX's every 10 months. OLEDX's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. OLEDX sells 1 one-off in-app purchase and KeepLit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OLEDX ships an update every 10 months, KeepLit every 9 days. The most recent releases landed on October 21, 2026 and October 11, 2026 respectively.
