# Devmaxx vs DataExpert / TechExpert

The clearest difference is rating: DataExpert / TechExpert at 5.0 against Devmaxx's 4.3. DataExpert / TechExpert also leads on monetization model (free with in-app purchases vs subscription). Devmaxx's advantage is ratings volume (541 vs 1) and update cadence (every 2 weeks vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Devmaxx sells 2 in-app purchases, starting at $8.99 per month and DataExpert / TechExpert sells 3 in-app purchases, starting at $59.99 per month. Whichever you choose, the download price is not the number that matters.
