Small apps for problems that are oddly specific.

One keeps braces elastics on schedule. The other gets you across New York without boarding the wrong train. Each does a single job and stays out of the way.

For braces elasticsBand Tracker

New band in. One tap. The clock does the rest.

Orthodontic elastics only work if you change them on time, all day, for months. Band Tracker turns that into one button and a countdown you can see without unlocking your phone.

  • One button to log a swap. It stamps the time and restarts your timer, set to whatever interval your orthodontist gave you.
  • A countdown on the lock screen. See time left at a glance, and log the next swap or snooze right from there.
  • Reminders that know about real life. Take the band out for a meal, put the bedtime band in, or pause alerts for a meeting. It keeps nudging until you swap.
  • A record you can show. Every swap is logged with wear time, late swaps, and bands used by day, week, or month. Export it as a spreadsheet.
  • Know when you're running low. Enter how many bands are in the bag and it counts down, including schedules that use more than one band per change.

No account. Nothing leaves your phone.
A reminder tool, not medical advice.

For getting across New YorkDaveigation

Directions from the friend who knows where you'll go wrong.

Map apps show the correct route. They don't tell you three different trains leave from that platform, or which one you'll board by mistake. Daveigation does, and ranks every option by how much of a pain it is, not by speed.

  • Ranked by hassle. Every boarding, transfer, ticket purchase, and walk is counted. Tap a score to see exactly what went into it.
  • Wrong-train traps called out. Each card flags the specific spots where people get turned around, in plain words.
  • Luggage and weather count. A 12-minute walk scores differently with a suitcase in the rain, and the forecast is pulled in for you.
  • Cost shown, never ranked. Every option's price sits side by side so you can decide what the easier trip is worth.
  • A card you can follow offline. The chosen route becomes a step-by-step card saved on the phone, with a companion on Apple Watch.

No AI guessing: the same trip always gives the same card.
New York first. Elsewhere it still ranks routes, with fewer traps.
