# Symbols vs Re

The clearest difference is rating: Re at 5.0 against Symbols's 4.5. Symbols's advantage is update cadence (every 6 weeks vs every 13 months) and device support (3 vs 1). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Symbols sells 6 in-app purchases, starting at $3.99 per month and Re sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Re holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 8 and 10 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

Symbols ships an update every 6 weeks, Re every 13 months. Both last shipped on June 1, 2026.
