ChoreStar is a household organiser for the jobs that need doing and the rewards they earn. You set the tasks, decide what each is worth, and approve work when it's marked finished — so the running total lives in the app instead of in your head. MANAGE THE HOUSEHOLD FROM ONE DASHBOARD - Assign tasks daily, weekly, monthly or one-off, to one person or everyone - Set point values, with optional reminder days - One review queue for everything waiting on you - Approve or decline in a tap; balances update instantly REWARDS YOU DEFINE - Build the reward list and price each one in points - Redemption requests come to you for approval, not spent automatically - Full history of every point earned and spent, filterable and exportable as a spreadsheet NO EXTRA ACCOUNTS TO MANAGE Household members join by scanning a code you generate. No additional email addresses, no passwords for you to reset. SHARE THE LOAD Invite a co-parent to manage the household with you. Both of you can assign, approve and adjust, and everyone stays in sync. ADS THAT STAY OUT OF THE WAY The free version shows one small banner on the dashboard. No pop-ups, no full-screen takeovers, nothing between screens, and no advertising on the household member's own view. Every ad is non-personalized and capped at a "G" content rating. CHORESTAR PREMIUM A one-time purchase, not a subscription. Removes advertising for everyone in the family and lifts the free limits on tasks, rewards and members. Bought once, applies to the whole household, nothing to renew or cancel. PRIVACY No behavioural profiling and nothing sold to advertisers. Delete your account and all of its data from inside the app at any time. Free version: 2 members, 8 tasks, 5 rewards. Terms: https://chorestar.cloudmigrationconsulting.net/terms/

Verdict
The clearest difference is ratings volume: One Calendar at 21K against ChoreStar's 5. ChoreStar's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. One Calendar sells 1 one-off in-app purchase and ChoreStar sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
ChoreStar holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: One Calendar has 21K ratings behind it against 5, so its average is the more settled of the two.
One Calendar ships an update fortnightly, ChoreStar every 10 days. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
