# OnefuncPlan vs ToDo Calendar Pro

The clearest difference is review sentiment: OnefuncPlan at 67% against ToDo Calendar Pro's 20%. OnefuncPlan also leads on ads (none vs shown) and update cadence (every 4 days vs every 2 months). ToDo Calendar Pro's advantage is rating (4.2 vs 4.0) and device support (4 vs 2). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. OnefuncPlan sells 13 in-app purchases, starting at $2.99 per month and ToDo Calendar Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ToDo Calendar Pro holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 67% of OnefuncPlan's written reviews are positive against 20% of ToDo Calendar Pro's, so the app with the better star average is not the one people write more warmly about.

OnefuncPlan ships an update every 4 days, ToDo Calendar Pro every 2 months. The most recent releases landed on September 19, 2026 and September 18, 2026 respectively.
