# Flow vs NightRing

The clearest difference is ads: Flow at none against NightRing's shown. Flow also leads on update cadence (every 2 days vs every 3 weeks). NightRing's advantage is iOS requirement (17.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Flow sells 3 in-app purchases, starting at $2.99 per 7 days and NightRing sells 6 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Flow ships an update every 2 days, NightRing every 3 weeks. The most recent releases landed on October 25, 2026 and October 16, 2026 respectively.
