Verdict
The clearest difference is rating: Spark Flex at 4.7 against NFI App's 2.7. Spark Flex also leads on update cadence (fortnightly vs every 31 months) and ratings volume (257 vs 3). NFI App's advantage is review sentiment (33% vs 0%) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Spark Flex holds the better App Store score, 4.7 against 2.7. That said, the two scores are not equally well evidenced: Spark Flex has 257 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of NFI App's written reviews are positive against 0% of Spark Flex's, so the app with the better star average is not the one people write more warmly about.
NFI App ships an update every 31 months, Spark Flex fortnightly. The most recent releases landed on October 10, 2026 and October 18, 2026 respectively.
