Verdict

The call

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.
