Verdict

The call

The clearest difference is update cadence: BoldVoice at every 2 days against Stache Flow's fortnightly. BoldVoice also leads on ratings volume (54K vs 5) and chart position (#113 vs unranked). Stache Flow's advantage is review sentiment (100% vs 74%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. BoldVoice sells 11 in-app purchases, starting at $14.99 per month and Stache Flow sells 3 in-app purchases, starting at $49.00 per month. Whichever you choose, the download price is not the number that matters.
