Verdict

The call

The clearest difference is price: NAS Pro at Free against Text Calculator's $0.99. NAS Pro also leads on rating (4.3 vs 2.0) and update cadence (every 3 weeks vs every 18 months). Text Calculator's advantage is in-app purchases (none vs 10) and iOS requirement (12.0 vs 18.0). On review sentiment, ads and device support there is nothing between them.
