Readrrr uses Rapid Serial Visual Presentation to show words one at a time in the same spot, and a natural voice can read each word aloud as it appears. Your eyes don't have to jump across lines, so you don't lose your place and read faster. Seeing and hearing every word at the same time also keeps your mind from drifting. Start at your normal pace and speed up as it gets comfortable. A Readrrr subscription or one-time purchase includes everything below: RSVP READER Every word has one letter marked in red for your eyes to rest on, so you never have to look for where the word starts. You can change the speed at any time. NARRATION Pick a voice and it reads along in sync with every word at any speed. The voice runs on your phone, so it works offline. SHORT READS Non-fiction you can finish in 10 to 20 minutes, on topics like history, health, science and economics. Each one is written to be read in Readrrr and sits in a collection with related reads. New ones come out every week, and you can suggest a topic. READ ANYTHING Import PDFs and EPUBs, send an article from Safari with one tap, paste text, or scan pages from a paper book. APP LOCKING Pick the apps that take up your day. Starting at 4 am they stay locked until you've read your daily word goal. Every day you hit it adds to your streak. If you really need one of them, you can unlock for 10 minutes once a day. HIGHLIGHTS Save any passage while you read. Readrrr sorts your highlights into themes and brings old ones back to you in the app and in a Home Screen widget, so you don't forget what you read. STATS Track your reading speed, words read and streak as they grow. SYNC Your library, reading position and stats stay in sync across your devices. SUBSCRIPTION Readrrr requires a subscription or a one-time purchase. Subscriptions renew automatically unless you cancel at least 24 hours before the current period ends. You can manage them in your App Store account settings. Privacy Policy: https://www.ocule.no/readrrr/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
Tercet

Most to-do apps let the list grow until it stops meaning anything. The pile becomes the reason nothing gets done. Tercet holds exactly three tasks a day. The three that make today count. Everything else waits in your backlog — captured, safe, and quiet. Your three live on your Lock Screen and Home Screen, so every glance at your phone is a glance at what matters. Check them off right from the widget. Finish all three, and Tercet tells you what that is: progress. THE RULES ARE THE PRODUCT - Today holds three tasks. Never more. - A finished task stays finished — no swapping it out for a fresh slot. - Finishing early doesn't unlock three more. The rest of the day is yours. - At midnight, finished tasks retire to your record and unfinished ones return to the backlog. Tomorrow starts clean. WHAT'S INSIDE - Lock Screen widget — your three at a glance, before you even unlock - Home Screen widgets in three sizes, with tap-to-check-off - Quick Add — one tap from your Lock Screen to typing a new task - Small Things — a quiet list for the errands that aren't one of the three - The Record — every finished day, kept forever. Proof it's working. - Streaks — honest ones. Finish all three or the flame resets. - A quote worth reading every time you finish, from the Stoics, builders, and finishers - Share the win — cards sized for Stories: your streak, the quote, the day. Never your task names. - Notes — one plain note per task for the details that don't belong in the title - A quiet celebration when you close out the day PRIVATE BY ARCHITECTURE Everything stays on your iPhone. No account, no cloud, no analytics, no tracking. We couldn't read your tasks if we wanted to. PAY ONCE Tercet is free for 14 days — the whole app, nothing held back. Then it's one payment of $9.99. No subscription, no ads, and your tasks are never held hostage. The idea is old and it works: there are only three things you have to get done every day. That's the signal. Everything else is the noise. Three lines make a verse. Three tasks make a day. Tercet.

Verdict
The clearest difference is update cadence: Tercet at every 3 days against Readrrr's fortnightly. On price, ads, in-app purchases and device support there is nothing between them.
