Thirty-Two: Black and white and square all over. Thirty-Two is a simple way to create and share drawings. Other than food and shelter there is no other need more powerful than the need to make small grayscale drawings. Old age is a myth, billions of people throughout history have simply died from lack of drawing in grids.* Thirty-Two is the solution!§ Features • Draw anything, as long as it fits in a thirty-two by thirty-two square! • Kick it 1-bit old school and draw with only black and white, or get ultra modern and use a plethora of grays!‡. • Duplicate a drawing, now duplicate a drawing! • Pinch to zoom while drawing, we know your chubby little fingers can't hit the squares you want, we're taking of that. See a little preview of the whole drawing while zoomed in, how cute. • Toolbar for the undo/redo to make them easier to get to. Didn't want to take three taps to undo something, we're considered two taps, but we decided one tap is best! • Super symmetrical mode, tap on the dotted line and pick vertical or horizontal so you can start drawing your favorite psychological inkblot tests. • Select and move pixels, tap and hold the pixels you want to move, tap other pixels to add to the selection, drag around, double tap to put the pixels in their final resting place. •Linear mode to draw straight lines. • Share from the app with your friends using sharing extensions. Any app that can share images will work, Mail, Messages, Facebook, Twitter, and any other third party apps that support sharing extensions. • Share with someone that's close to you, using AirDrop. • Watch your drawings on Apple Watch! • Search for your beauteous drawings in Spotlight. • Dance the hand jive while using Handoff between devices. Ideas for drawings • Unflattering portraits of your friends that you post online without their permission. • Replace the icons on your thirty year old computer. • Make reproductions of your favorite artist's square, black and white masterpieces. • Your hipster bike. • Your hipster glasses. • Your hipster bird you put on stuff. • Your hipster watch. • Your steampunk tophat. • Your hipster shark. • Drawings of pets you wished were yours, so that your sad meaningless life had a ray of hope.° • Illustrate the fourteen stations of the cross. • Illustrate the twelve signs of the zodiak. • A taxi-cab. • An old boot. • A urinal on it's side, with some letters scribbled on it. • And literally a couple more things... *Does not cure old age, athelete's foot or the plague. §There is no solution, because there is no problem. ‡A plethora in this context means six. °Users of Thirty-Two are prone to bouts of existential angst.

Some dates deserve more than a calendar entry. Countdown turns the moments you can't wait for into living, glowing timers with a proper celebration when they finally arrive. BACKGROUNDS THAT GET IT • The background matches your event: type "Ibiza Trip" and the app finds real imagery of the place, tinted by its live time of day. • Or pick any photo from your library. • Hand-tuned themes: Aurora, Sunset, Neon Noir, Midnight Gold and more. COUNT EVERY SECOND • Glowing progress ring with days, hours, minutes, seconds. • The last 10 seconds go full-screen cinematic with a haptic heartbeat. • Confetti storm and celebration screen at zero. • Anticipation stats: sleeps left, weekends left, how far you've come. EVERYWHERE YOU LOOK • Home screen widgets in three styles: Ring, Flip Clock, Minimal. • Live Activity in the Dynamic Island for the final 24 hours. • Ambient nightstand mode. • Notifications at the moment itself, plus halfway, 30-day, 1-week and 1-day milestones. SHARED MOMENTS • Share a countdown via iCloud and count down together. • See the moment across world time zones. • Finished countdowns become keepsakes: add photos, count the days since. QUICK TO ADD • Siri: "Add a countdown" • Import straight from your calendar • Paste any text, "flight to Lisbon Aug 14 6am" becomes a countdown. Free. No ads. No tracking. Your data stays yours.

Verdict
The clearest difference is rating: Teller1 at 5.0 against Thirty's 3.2. Teller1 also leads on update cadence (every 4 days vs every 3 months). Thirty's advantage is ratings volume (10 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
