HistoryCalc is a calculator built around a history tape—so you can see what you calculated, fix a line, and keep going.
WHAT YOU GET
• Everyday calculator for basic math
• History tape on the same screen—scroll, copy, edit, and add short notes
• Discount mode: enter a price, tap common percent-off buttons, see savings and the final price
• Free to try: keep the latest 10 tape entries (notes included)
• Share or save a clean image of any result (and share as text)
• One-time purchase: unlimited tape, search, and favorites
MADE FOR REAL USE
• Edit a past expression and recalculate—new results are added as new tape lines by default (optional replace)
• Save discount results back to your tape
• No account needed to calculate; sign in only when you buy or restore
PRIVACY
• Calculation history stays on your iPhone
• Sign-in is only for your purchase entitlement—your tape is not cloud-synced
A focused calculator tool: history tape plus fast discount pricing.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Equals now shows the full calculation, not just the answer. For example, 4-1-1 shows 4-1-1=2, and the same expression is saved on your tape. Free tape also shows n / 10 and tells you before the oldest entry is replaced.
