Verdict

The call

The clearest difference is in-app purchases: ODevice at none against Text to Speech's 1. ODevice also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 15 months). Text to Speech's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price there is nothing between them.
