# ELink Invoice vs Sparky

The clearest difference is ads: Sparky at none against ELink Invoice's shown. Sparky also leads on update cadence (weekly vs every 4 weeks) and ratings volume (7 vs 1). ELink Invoice's advantage is rating (5.0 vs 4.7) and iOS requirement (13.0 vs 17.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. ELink Invoice sells 2 one-off in-app purchases and Sparky sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ELink Invoice holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sparky has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 0% and 0% positive.

ELink Invoice ships an update every 4 weeks, Sparky weekly. The most recent releases landed on June 5, 2026 and September 7, 2026 respectively.
