Check Wheelchair Range Against Planned Distances
Manual and powered chairs are honest about distance in a way day plans are not. Subtract each day’s planned distance from the usable range your reserve leaves, and see which day the battery spends before you do.
1 · day | planned distance | range per charge

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the range day ladder: your day | planned distance | range per charge stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Terrain, temperature and battery age move real range well below the printed one. After: the range day ladder shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Range arithmetic on the distances and reserves you supply. Not mobility, medical or equipment advice; range, load limits and charging practice come from the device manufacturer and your therapist or mobility provider, and unexpected weakness or pain needs clinical review.

Range arithmetic on the distances and reserves you supply. Not mobility, medical or equipment advice; range, load limits and charging practice come from the device manufacturer and your therapist or mobility provider, and unexpected weakness or pain needs clinical review.
- Method: The margin held for the detour, the closed lift, the extra stop. Twenty percent is prudent; zero percent is how days end in a taxi.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.
- Google’s official pricing page, fetched 2026-09-29, lists free-tier access including AI Studio. Optional formatting only; limits and availability can change. Free-tier content may be used to improve products. Never paste private records there.

Optional AI formatting, not calculation
For this range day ladder, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a range day ladder. Return plain rows only: day | planned distance | range per charge. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: day | planned distance | range per charge. No AI response is executed as code.
