# i vs i4Flash

The clearest difference is rating: i at 2.1 against i4Flash's 1.4. i also leads on ratings volume (80 vs 12). i4Flash's advantage is update cadence (every 2 weeks vs every 3 months) and iOS requirement (9.0 vs 11.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

i holds the better App Store score, 2.1 against 1.4. That said, the two scores are not equally well evidenced: i has 80 ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 10% of i's written reviews are positive against 5% of i4Flash's.

i ships an update every 3 months, i4Flash every 2 weeks. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
