Solve quick sums against a gentle clock as you wander a winding path through five peaceful, illustrated worlds, with soft music to keep you company. FIVE WORLDS, 75 LEVELS • Lily Pond: warm up with addition. • Mossy Forest: subtraction joins in. • Signpost Village: multiplication, starting with the times tables. • Butterfly Garden: division joins the mix. • Candlelit Festival: the toughest sums of all. Each world builds slowly, so the sums grow with you and never feel out of reach. THREE STARS TO CHASE Finish a level with time to spare to earn up to three stars. Replay any level to beat your time and fill in the gaps. SECRET LEVELS Earn every star in a world to open its secret level: a longer, quicker run along a moonlit path. ENDLESS MODE Pick your sums and your pace, then see how far you can go. Every right answer wins a little time back, and your best run is saved. MADE TO RELAX • A big, clear number pad that is easy to tap. • Pause whenever you need to. • Music, sound effects and haptics you can switch off. • No account, no adverts and no internet needed to play. TRY IT FREE Play all 15 levels of Lily Pond for free. Unlock the full game with a single purchase to open the other four worlds, the secret levels and endless mode. There is no subscription. ## Sum Serenity Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/8f/ab/6a/8fab6adb-ed47-55e2-090e-cc82e76827af/bbfcd19c-347f-4346-be33-89638a332676_Screenshot_7.png/1242x2208.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/a1/30/25/a13025ba-aa3f-be46-7f59-2ab1507b2c28/0cabdf4f-f36c-4d56-8700-9695ecbc1892_Screenshot_8.png/1242x2208.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/44/97/4a/44974a31-1baa-80cf-a4c1-82ad0dd650ef/74c5d894-c083-44b5-94e2-d12751ac7dc0_Screenshot_6.png/1242x2208.png) ## Sum Serenity Rating Breakdown in United Kingdom - 5 stars: 3 (100%) - 4 stars: 0 (0%) - 3 stars: 0 (0%) - 2 stars: 0 (0%) - 1 stars: 0 (0%) ## Sum Serenity Available In - [United Kingdom](https://apptail.io/app/sum-serenity-mental-maths-Mgip/united-kingdom) - [Netherlands](https://apptail.io/app/sum-serenity-mental-maths-Mgip/netherlands) - [Bahrain](https://apptail.io/app/sum-serenity-mental-maths-Mgip/bahrain) - [Canada](https://apptail.io/app/sum-serenity-mental-maths-Mgip/canada) - [Switzerland](https://apptail.io/app/sum-serenity-mental-maths-Mgip/switzerland) - [Chile](https://apptail.io/app/sum-serenity-mental-maths-Mgip/chile) - [Cyprus](https://apptail.io/app/sum-serenity-mental-maths-Mgip/cyprus) - [Czechia](https://apptail.io/app/sum-serenity-mental-maths-Mgip/czechia) - [Dominican Republic](https://apptail.io/app/sum-serenity-mental-maths-Mgip/dominican-republic) - [Egypt](https://apptail.io/app/sum-serenity-mental-maths-Mgip/egypt) - [Spain](https://apptail.io/app/sum-serenity-mental-maths-Mgip/spain) - [Finland](https://apptail.io/app/sum-serenity-mental-maths-Mgip/finland) - [Croatia](https://apptail.io/app/sum-serenity-mental-maths-Mgip/croatia) - [Ireland](https://apptail.io/app/sum-serenity-mental-maths-Mgip/ireland) - [Israel](https://apptail.io/app/sum-serenity-mental-maths-Mgip/israel) - [India](https://apptail.io/app/sum-serenity-mental-maths-Mgip/india) - [Italy](https://apptail.io/app/sum-serenity-mental-maths-Mgip/italy) - [Japan](https://apptail.io/app/sum-serenity-mental-maths-Mgip/japan) - [Lebanon](https://apptail.io/app/sum-serenity-mental-maths-Mgip/lebanon) - [Lithuania](https://apptail.io/app/sum-serenity-mental-maths-Mgip/lithuania) - [Luxembourg](https://apptail.io/app/sum-serenity-mental-maths-Mgip/luxembourg) - [Malaysia](https://apptail.io/app/sum-serenity-mental-maths-Mgip/malaysia) - [Nigeria](https://apptail.io/app/sum-serenity-mental-maths-Mgip/nigeria) - [Norway](https://apptail.io/app/sum-serenity-mental-maths-Mgip/norway) - [Nepal](https://apptail.io/app/sum-serenity-mental-maths-Mgip/nepal) - [Pakistan](https://apptail.io/app/sum-serenity-mental-maths-Mgip/pakistan) - [Poland](https://apptail.io/app/sum-serenity-mental-maths-Mgip/poland) - [Russia](https://apptail.io/app/sum-serenity-mental-maths-Mgip/russia) - [Singapore](https://apptail.io/app/sum-serenity-mental-maths-Mgip/singapore) - [Slovenia](https://apptail.io/app/sum-serenity-mental-maths-Mgip/slovenia) - [Türkiye](https://apptail.io/app/sum-serenity-mental-maths-Mgip/turkey) - [Taiwan](https://apptail.io/app/sum-serenity-mental-maths-Mgip/taiwan) - [Ukraine](https://apptail.io/app/sum-serenity-mental-maths-Mgip/ukraine) - [United States](https://apptail.io/app/sum-serenity-mental-maths-Mgip/united-states) - [United Arab Emirates](https://apptail.io/app/sum-serenity-mental-maths-Mgip/united-arab-emirates) - [Vietnam](https://apptail.io/app/sum-serenity-mental-maths-Mgip/vietnam) - [Belgium](https://apptail.io/app/sum-serenity-mental-maths-Mgip/belgium) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
