History 100: A 100 day history challenge
$9.99 to unlock Your first pack is on us.

Every day you fill in one history card: what happened, why it mattered and what it teaches now. Days 1 to 5 take you from the first artists and early farming to the invention of writing, the pyramid builders and the Polynesian wayfinders.

Preview the first 7 days
Every day has 3 goals: your daily core (the same every day), Task 2 and Task 3, each with a short why. Open a day to read all three.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Explain why early people painted cave walls
Source topic: cave art. Tens of thousands of years ago, people in places as far apart as Indonesia, France and Australia painted animals and hand outlines on rock walls. Using your source, write two or three sentences on the back of your card: how the art was made and one reason researchers think people made it. Mark which part is evidence and which is a researcher's interpretation. Done when both are written.
Why: Separating what the evidence shows from what experts suggest is the first skill of reading history well.
Task 3
Trace your hand the way early artists did
Lay your hand flat on a sheet of paper and trace around it with a pencil or marker. Add the date. If your source showed a stencil handprint, compare its shape to yours.
Why: Many cave handprints were made by blowing pigment around a hand, so tracing yours links you to one of the oldest human signatures.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Trace how farming led to towns
Source topic: the beginnings of farming. About 10,000 years ago, people in several parts of the world, separately, began planting crops and raising animals: wheat in the Middle East, rice in China, maize in Mexico, potatoes in the Andes. Using your source, write a chain of three steps on the back of your card showing how farming led to villages and then towns. Done when each step points to something in your source.
Why: Seeing the steps from planting crops to building towns explains where much of settled life began.
Task 3
List five foods in your kitchen and where they began
Pick five foods you have at home. Look up where each was first grown or domesticated and write one line for each: food, place and rough time.
Why: Tracing everyday foods back to where they were first grown shows how global your plate already is.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Work out what early writing was used for
Source topic: the invention of writing. Writing was invented separately in a few places, including Mesopotamia, Egypt, China and Mexico. In Mesopotamia it began as marks pressed into clay to keep track of grain and animals. Look closely at one example of early writing in your source and write on the back of your card who likely made it, what it records and what that tells you about the society. Three lines is done.
Why: Reading an object for clues about the people who made it is how historians work with very old evidence.
Task 3
Invent five symbols for things you own
Draw five simple picture symbols, each standing for one thing you own, like a cup or a key. Then write a short sentence using only your symbols and see if it still makes sense.
Why: Making up your own picture symbols shows how hard and how clever it was to invent writing from nothing.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Weigh the evidence about who built the pyramids
Source topic: the workers who built the Great Pyramid. It was built about 4,500 years ago. Archaeologists found the town where its workers lived, with bakeries and signs of medical care, which suggests organized crews rather than the enslaved crowds of old movies. On the back of your card, list two pieces of evidence your source gives and write one sentence on what they suggest about the workers. Done when both are named.
Why: Weighing physical evidence against popular myths helps you tell a well supported story from a familiar one.
Task 3
Sketch one way the stones may have been moved
Sketch one method your source mentions, or a simple ramp and sledge if it mentions none. Label the parts and put a question mark beside any step that is still debated.
Why: Drawing a method and marking what is uncertain shows how historians work with clues rather than certainty.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Explain how Polynesian wayfinders navigated
Source topic: Polynesian wayfinding. Over many centuries, Polynesian navigators settled islands across the Pacific, from Hawaii to New Zealand to Rapa Nui. They found their way by stars, ocean swells, clouds and birds, with no instruments. On the back of your card, explain two of these clues in your own words: what the navigator watched and what it told them. Done when both are explained.
Why: Explaining a skill in your own words shows whether you understood the source or only read it.
Task 3
Find the Pacific triangle on a map
Use a free online map or an atlas. Find Hawaii, New Zealand and Rapa Nui, and note the rough distance between two of them.
Why: Seeing the huge distances between those islands makes the scale of their voyages clear.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Judge the fairness of three of Hammurabi's laws
Source topic: the laws of Hammurabi. About 3,700 years ago, the Babylonian king Hammurabi had nearly 300 laws carved on a tall stone for all to see. Punishments were harsh and depended on whether you were rich, poor or enslaved. Choose three laws in translation from your source. On the back of your card, write for each one who it protected and who it treated harshly. Done when all three are noted.
Why: Asking who a law protects and who it harms is a question you can bring to any law, old or new.
Task 3
Write three laws you would carve in stone
Write three short laws for a group you know, like a household, team or club. For each, write the penalty you think is fair and one line on why.
Why: Choosing your own laws makes you think about fairness the way every lawmaker in history has had to.
Daily core Same every day
Read one short history source
Why: Noting where each fact comes from builds history you can back up, not just stories you have heard.
Task 2
Start your history timeline
Easy day. Draw a long line across a sheet of paper, or start a note, and place the topics from your Day 1 to 6 cards on it in order with their dates or periods. Leave lots of room, since review days will add more. Keep your history cards together in one envelope, box or notes folder named History cards.
Why: A timeline shows how separate stories connect across time.
Task 3
Write your history baseline explanation
Pick one card from Days 1 to 6. Without looking at it, write five sentences on what happened, when, why it mattered and how we know. Then check the card and mark each sentence right, partly right or missing. Save it as a note titled History baseline (Day 7). You will compare with it on Days 25, 50, 75 and 100.
Why: A short explanation saved now gives you something real to compare with at each checkpoint.
The other 93 days unlock when History 100 is yours.

The app launches December 15, 2026. Join the waitlist before then and the Early Adopter badge is yours. The group starts Day 1 on January 1, 2027, and you can start earlier if you like. Sign up after launch and History 100 is ready when you are. Your first pack is on us.
How History 100 works
What you do each day
3 goals a day. Your daily core, Read one short history source, is the same every day. The other two are new each day: Task 2 builds the habit and Task 3 adds a different angle. Each one comes with a short why.
Time and effort
Most days fit around a normal day, all 3 goals together. Some days are lighter, and nothing needs to happen at a set time.
Difficulty and pace
Gentle. Starts small and builds slowly. Good if you're brand new to this. Milestone badges at 10, 25, 50 and all 100 fully completed days mark how far you came.
Easier alternatives and rest days
Most goals have an easier alternative. “Choose an easier alternative” puts it in its place, and it counts the same as the original goal: the same square, streak and rewards. A rest day protects the streak on days life happens.
Pausing or switching
With another challenge going, you can pause this one any time. Resume later and you pick up on the same day you left. Remove it instead and your history stays: ticks, notes and photos. You always keep at least one challenge going. Up to 3 packs can be active at once, your main challenge included. Active and scheduled packs count; paused, finished and not started ones don't. You can own as many packs as you like and start them later.
What you own
Unlock History 100 on its own ($9.99 or a free credit) and it's yours forever, to replay any time. All Access opens every pack while you're subscribed. Credits never expire, so use them when you're ready.
Pack guide
Reading and evidence
Use museum or archive material where possible and compare a scholarly account when sources disagree. Record time, place, people, evidence and uncertainty. Do not present a modern craft activity as an authentic reconstruction. Suggested starting collections: https://www.loc.gov/collections/, https://www.si.edu/ and https://www.worldhistory.org/ (secondary orientation only; check against institutional sources). The app does not currently supply a vetted reading for every day.
History cards and your history timeline
Each day's core makes one history card. The front holds the topic, the source title, who published it, the date or period and one fact the source supports. The back holds what you work out in Task 2. Keep your cards together in one envelope, box or notes folder named History cards. Your history timeline starts on Day 7, and review days add new cards to it. Your History baseline (Day 7) and History checks (Days 25, 50, 75 and 100) are short notes saved alongside.
How to use task details
The task title names the action. Open its details for the method, examples and any relevant precautions; Why explains the purpose. Save the stated output or record the action you actually took. Paper and other suitable tools are valid alternatives. Do not mark a real-world result complete merely because a planning note was written. Writing tasks can be done in Journal, on paper or anywhere you like. Linking them to Journal is optional.
Focus blocks
For any study or practice task: put your phone in another room or face down, write the one thing you will do, and set a timer for 10 to 25 minutes. When your mind wanders, notice it and come back. Stop when the timer rings and note where you got to.
Earn 4 milestone badges
10, 25, 50 and all 100 fully completed days of History 100: your first achievement, then bronze, silver and gold. Days finished late count too.
