# Frontier X vs Dr Alo

The clearest difference is rating: Dr Alo at 5.0 against Frontier X's 4.6. Dr Alo also leads on monetization model (free vs free with in-app purchases) and review sentiment (100% vs 82%). Frontier X's advantage is ratings volume (317 vs 16). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Frontier X sells 2 in-app purchases, starting at $14.99 per month and Dr Alo sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Dr Alo holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Frontier X has 317 ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 82% of Frontier X's written reviews are positive against 100% of Dr Alo's.

Frontier X ships an update every 3 weeks, Dr Alo fortnightly. The most recent releases landed on September 25, 2026 and August 16, 2026 respectively.
