# RX vs Tech Aide

The clearest difference is in-app purchases: RX at none against Tech Aide's 2. RX also leads on ratings volume (70 vs 3) and iOS requirement (13.0 vs 15.0). Tech Aide's advantage is ads (none vs shown) and update cadence (weekly vs every 6 months). On price, monetization model and device support there is nothing between them.

Both are free to download. Tech Aide sells 2 in-app purchases, starting at $4.99 per month. RX asks for nothing beyond the download.

Tech Aide holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: RX has 70 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 90% of RX's written reviews are positive against 100% of Tech Aide's.

RX ships an update every 6 months, Tech Aide weekly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
