Verdict

The call

The clearest difference is rating: Viro at 4.9 against JouleBug's 4.4. Viro also leads on review sentiment (100% vs 70%) and update cadence (weekly vs every 3 months). JouleBug's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, ratings volume, in-app purchases and device support there is nothing between them.
