# Spektrum+ vs AbiFlow

The clearest difference is update cadence: AbiFlow at every 3 weeks against Spektrum+'s every 4 months. Spektrum+'s advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Spektrum+ sells 10 in-app purchases, starting at $7.99 per month and AbiFlow sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Spektrum+ ships an update every 4 months, AbiFlow every 3 weeks. The most recent releases landed on November 13, 2026 and November 14, 2026 respectively.
