# Numem vs Spectral

The clearest difference is ads: Spectral at none against Numem's shown. Spectral also leads on update cadence (fortnightly vs every 7 months). Numem's advantage is ratings volume (29 vs 6) and iOS requirement (18.0 vs 26.0). On price, rating, in-app purchases and monetization model there is nothing between them.

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

Spectral holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 29 and 6 respectively.

Numem ships an update every 7 months, Spectral fortnightly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
