Verdict

The call

The clearest difference is rating: Todo at 4.4 against Graph's 2.9. Todo also leads on ratings volume (391 vs 15) and review sentiment (46% vs 30%). Graph's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (monthly vs every 2 months). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Graph sells 1 one-off in-app purchase and Todo sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
