# Stackr vs IQONIC

The clearest difference is rating: IQONIC at 5.0 against Stackr's 4.4. IQONIC also leads on review sentiment (100% vs 68%) and device support (3 vs 1). Stackr's advantage is ads (none vs shown) and ratings volume (225 vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stackr sells 7 in-app purchases, starting at $7.99 per 7 days and IQONIC sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

IQONIC holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Stackr has 225 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 68% of Stackr's written reviews are positive against 100% of IQONIC's.

Stackr ships an update weekly, IQONIC every 5 days. Both last shipped on November 9, 2026.
